Mr. Kirk asked his students to compare 0.196 and 0.15. Four of his students correctly answered that 0.196 is greater than 0.15, but they gave different explanations when asked to describe their strategies to the class. Indicate whether each of the following student explanations provides evidence of a mathematically valid strategy for comparing decimal numbers. -0.196 is larger because there is one in the tenths, and then nine hundredths is more than five hundredths. And then I'm done. -0.196 is greater because in the thousandths place six is greater than five, and in the hundredths place nine is greater than one. -0.196 is bigger than 0.15 because if it is three numbers long, it will always be bigger than if it is two numbers long. -0.196 is more than 0.15 because nineteen hundredths is bigger than fifteen hundredths.

Ayana's banana bread recipe uses 3 bananas to make 2 loaves of banana bread. Natalie's banana bread recipe uses 4 bananas to make 3 loaves of banana bread. Whose recipe results in a greater amount of banana in each loaf of banana bread? Mr. Ma asked his class to solve the word problem shown. Three students correctly answered that Ayana's recipe results in a greater amount of banana in each loaf, but they gave different explanations when describing their strategies to the class. Indicate whether each of the following student explanations provides evidence of a mathematically valid strategy for determining whose recipe results in a greater amount of banana in each loaf. -In Ayana's recipe there are 3 bananas for 2 loaves, so there is a whole banana for each loaf and you split the last banana in half. In Natalie's recipe there is one banana for each loaf and the fourth banana is split in 3. So in Ayana's loaf there are 1 and a half bananas, and in Natalie's there are 1 and a third, and a half is more than a third. -In Ayana's recipe the bananas are split between only 2 loaves, while in Natalie's recipe the bananas are split between 3 loaves. If I have to split a cookie, I would rather split it in two because I get more, so Ayana's loaves contain more bananas. -Ayana makes only 2 loaves and Natalie makes 3 loaves. If they made the same number of loaves, like 6, then Ayana would use 9 bananas and Natalie would use 8. So Ayana's loaves have more because 9 is more than 8.

An upper-elementary school teacher has paired the following version of "The Frog Prince" fairy tale and the related poem "The Frog's Tale" for students to read and analyze. The Frog Prince Once upon a time, there lived a beautiful princess with shiny hair. She was the only daughter of a king.Sometimes that meant she was lonely, but the king tried to keep her happy by giving her all that she asked for. After all, he was richer than anyone else in the kingdom. he even gave her a glistening golden ball. she loved to bounce it through the castle's gardens, running after it all the way. One day, she bounced the ball too hard, and it got away from her and dropped into a well. she began to cry. Suddenly, a large, brown, wart-covered frog hopped out of the well and smiled at her. In a croaky voice, he asked, "Why are you crying, princess?" "Oh, I have dropped my golden ball into the well, and I fear I shall never get it back!" she told him. The ugly frog reassured her, "My dear, I can help you get your ball, but if I do, you must be my friend and let me eat things from your plate and stay beside you." "Me? Be your friend?" The princess wrinkled her nose at this idea, but she doubted he would be successful, so she agreed. At once, the frog dove into the well and returned with her golden ball, safe and sound. Although she was grateful to have her ball returned, she was very unhappy about having the frog return to the palace with her. As promised, however, the princess let the frog eat from her plate and sleep on her feather pillow. Soon the princess began to enjoy the frog's company and feel less lonely. She spoke kind words to him as a friend might speak. One night, she said, "Little frog, thank you for being my friend." She closed her eyes and gave the frog a quick kiss on his warty, cold head. Suddenly—poof!—a light flashed, and a handsome prince stood before her. He said, "My dear princess, I have been under the spell of a sorcerer for over a year and forced to live in the body of a frog. Your kiss has broken the spell! Thank you!" The princess fell in love with the prince and lived happily ever after. The Frog's Tale Why would I want to be a princeand wear a heavy crown,when I can wriggle in the mud so cool and thick and brown? (5)Why smooch with all the princesses and give them golden rings,or ride in pumpkin chariotsand buy a lot of things?A frog's life is far richer than (10)all that could ever before here I'm safe and comfortable—and ooze and slime are free.I wouldn't trade the life I have for any princely thing;(15)I'll stay here where my castle is—since in this pond I'm king! Below is one student's summary of the poem. "In the poem, the frog is talking about how he'd rather be a frog in the mud than be a prince and have to wear a crown. He doesn't want to kiss the princess or ride in pumpkin chariots. The frog has more money than the prince does, so he's happier. He is in charge of the pond and the pond is his home, so that's where he wants to stay." Which three of the following describe strengths of the student summary? A.The speaker of the poem is identified. B.The allusion in line 7 is explained. C.The play on words in lines 9-10 is accurately interpreted. D.The figurative language in lines 15-16 is correctly interpreted. E.The organization of the summary is parallel to the structure of the poem.

A teacher has students read the following background text about guajira music and the excerpt from a memoir by Alma Flor Ada. Background Text Cuban music is unique because it reflects both the rich history of its homeland as well as influences from many cultures around the world. Early Cuban music was born through the union of African and Spanish music. As the music evolved, it picked up influences from other cultures, including French, North American, and Jamaican. One type of Cuban music is musica guajira, which translates to "country music" in Cuban Spanish. At the time the first guajira music emerged, rural life was often extremely difficult, and poverty and injustice were present; this came through in the music. Guajira music can be played in a minor key, reflecting these hardships, or in a major key, reflecting joy and hope—but it is always peaceful in style. It is often played on the guitar although it can be played on many types of acoustic instruments. Finally, it has poetic, rhyming lyrics that usually describe the beauty of the Cuban countryside and the splendor of the rural Cuban people. Memoir Excerpt Since the accident, there had been no accordion music at night. Now that the bandages had come off, the nightly silence felt even more oppressive to me. I began to go to the river with Samoné to help him bring in the grass. Before, whenever we had spent time together, he had told me stories about bright rabbits and nasty foxes. Yet now all that I heard from him were heavy sighs. It was as though the purpose in his life had left him, drained out through the hand he could no longer use. Then Samoné began to disappear in the afternoons. No one knew where he went. Nobody said much about it, but I could see worried looks on my mother's face when he began to skip dinner too. Sometimes, when he was gone, I felt as though I heard an echo of his music. Then one night, when I was already in bed, I did hear it. Somewhat tentative, and not as bright as it had been before, but there it was: the beautiful sound of a guajira, a gentle love song from the Cuban countryside. Samoné, practicing tenaciously in solitude, had found a way to create music again. I jumped out of bed, tiptoed into the dining room, and looked out into the courtyard. There he was, poised somewhat awkwardly on his taburete, opening and closing the accordion with his knees while he played the keys with his left hand. Yet the music sounded soft and clear, accompanied by Samoné's familiar hum, while the rays of moonlight, filtering through the branches of the flame trees, shone upon the smile that lit his face. —Alma Flor Ada, from Where the Flame Trees Bloom The teacher has the students respond to the prompt "What is a primary character trait of Samoné? Use text evidence to support your answer." Which of the following student responses should the teacher select as the best model of using text evidence to support an inference? A."Samoné has passion. When he can't play his music, he has 'heavy sighs' because he can't play and his skill is 'drained out through the hand he could no longer use.' Once he figures out a way to play again, he is happy because you see 'the smile that lit his face.'" B."Samoné is determined. Samoné is not happy because he can't do what he loves, so he keeps trying until he on once again finds his happiness in playing his 'accordion music at night.' If a person tries hard to do something hard, he feels better when he accomplishes it." C."Samoné has many difficulties since his hand is hurt. It says that 'the purpose in his life had left him.' He has trouble doing the things he did before. And he cannot play his music as well." D."Samoné is very smart. He asks the narrator to go with him to 'bring in the grass,' since it is hard for him now. Even though his hand no longer works, he is able to figure out how to play his accordion again."

A."Samoné has passion. When he can't play his music, he has 'heavy sighs' because he can't play and his skill is 'drained out through the hand he could no longer use.' Once he figures out a way to play again, he is happy because you see 'the smile that lit his face.'"

The following is an excerpt of a transcript from a class discussion that took place after students read an informational text about deforestation. Teacher: To what extent do the costs of deforestation outweigh the benefits? Erin? Erin: Well, I think, in my mind, people shouldn't cut down the trees in the rain forests. It might help us get things we need, like paper and wood, but the article said how animals are becoming extinct because they have no place to live. And I feel sorry for the animals, so really it's a bad idea. Teacher: Excellent. What do you think, Tim? Tim: We shouldn't cut down the rain forests. Teacher: OK. Doug? Doug: It's harmful for humans because we read that part about how the machines they use to cut down the trees create air pollution. Teacher: Right, the machinery contributes to carbon emissions. Excellent. Cane? Cane: But cars pollute the air, too. It's kind of the same thing. Plus, we need to get wood from somewhere, or else how can we make new buildings? Teacher: James? James: Well, I guess we can plant new trees to get more wood. But even if we plant new trees after we cut down parts of the rain forest, it takes forever for them to grow. So pretty much, the trees won't grow in time for other generations to use them. Kelly: Maybe people who cut down the trees are just thinking about what they need right now. But they aren't thinking about the future. . . like, the long-term effects. Which two of the following elements of discussion are evident in the transcript?

Questions 11-16 refer to the following scenario. A teacher is reading and discussing the following article with students. Amazing Sea Lions *When we scuba dive off the California coast, we often meet playful sea lions. They sneak up behind us, swim circles around us, and perform loops, spins, and somersaults. Then they hang motionless upside down, staring at us as if daring us to try the same tricks. We can only stare back at them in amazement. How do they do that? And without using the scuba tanks, masks, and wet suits that we need to swim underwater? The answer lies in the fact that sea lions' bodies—inside and out—are suited for their diving lifestyle. A combination of features—from their shape to their broad, flat flippers to what is in their blood—allows them to thrive in their underwater world.* No Scuba Tanks Sea lions don't need scuba tanks because, in a way, they carry their own oxygen supply with them. Sea lions have more blood than we do. And their blood contains more hemoglobin, which is a protein that carries oxygen to wherever it is needed in the body. Sea lions also have a large amount of myoglobin, another protein that carries oxygen through muscles. So sea lions can store lots of oxygen in their blood and muscles. They don't have to depend only on the air in their lungs for oxygen during their dives. When they dive, sea lions make good use of this oxygen by conserving their energy. They actually lower their metabolism underwater. Their hearts beat more slowly, and any functions that are not needed for diving, such as digestion, slow down or stop. Another energy-saving feature is the shape of sea lions' bodies, which is streamlined and sleek. Their long, smooth shape helps them glide easily through the water so they use less energy while swimming. No Wet Suits Sea lions stay warm underwater because they have a layer of fat called blubber around their bodies. They don't need the wet suits that scuba divers wear to keep from getting cold. The blubber also smooths and rounds out their bodies, which helps streamline their shape. No Masks or Flashlights Scuba divers have to wear face masks in order to see underwater. They also sometimes use flashlights to help them see clearly. But sea lions can see well underwater, even when it's dark. Their large, sensitive eyes have more photoreceptor cells than human eyes do. These cells capture light so that the images of things a sea lion sees can be sent to its brain. These extra cells allow sea lions' eyes to work well in faint light where it would be too dim for us to see anything. Face masks also keep divers from breathing in water. How do sea lions keep water out of their noses while swimming in the ocean? Their nostrils are closed underwater. This is the normal, relaxed position for them. Unlike humans, sea lions have to think about opening up their nostrils to breathe. Growing Up Diving Sea lion mothers come ashore in large groups to have their pups. The pups are born in early summer, usually between May and July. In a matter of weeks, the pups are exploring the water. Within a few months, they are in the ocean, playing and diving together. Using their strong front flippers, they speed through the water. Their flexible backbones allow them to twist and twirl, performing fantastic underwater acrobatics. Sea lions are incredible creatures. Their bodies allow them to dive with ease and freedom. Human divers will never achieve their grace or skill in the water, but we can enjoy watching them! In the highlighted section, the author uses which of the following writing techniques? Select all that apply. A.Vivid imagery to create a spirited tone B.Questions to make the reader focus on the sea lions' abilities C.Dashes to separate ideas that are unrelated to the article

Questions 11-16 refer to the following scenario. A teacher is reading and discussing the following article with students. Amazing Sea Lions When we scuba dive off the California coast, we often meet playful sea lions. They sneak up behind us, swim circles around us, and perform loops, spins, and somersaults. Then they hang motionless upside down, staring at us as if daring us to try the same tricks. We can only stare back at them in amazement. How do they do that? And without using the scuba tanks, masks, and wet suits that we need to swim underwater? The answer lies in the fact that sea lions' bodies—inside and out—are suited for their diving lifestyle. A combination of features—from their shape to their broad, flat flippers to what is in their blood—allows them to thrive in their underwater world. No Scuba Tanks Sea lions don't need scuba tanks because, in a way, they carry their own oxygen supply with them. Sea lions have more blood than we do.

An upper-elementary school teacher has paired the following version of "The Frog Prince" fairy tale and the related poem "The Frog's Tale" for students to read and analyze. The Frog Prince Once upon a time, there lived a beautiful princess with shiny hair. She was the only daughter of a king.Sometimes that meant she was lonely, but the king tried to keep her happy by giving her all that she asked for. After all, he was richer than anyone else in the kingdom. he even gave her a glistening golden ball. she loved to bounce it through the castle's gardens, running after it all the way. One day, she bounced the ball too hard, and it got away from her and dropped into a well. she began to cry. Suddenly, a large, brown, wart-covered frog hopped out of the well and smiled at her. In a croaky voice, he asked, "Why are you crying, princess?" "Oh, I have dropped my golden ball into the well, and I fear I shall never get it back!" she told him. The ugly frog reassured her, "My dear, I can help you get your ball, but if I do, you must be my friend and let me eat things from your plate and stay beside you." "Me? Be your friend?" The princess wrinkled her nose at this idea, but she doubted he would be successful, so she agreed. At once, the frog dove into the well and returned with her golden ball, safe and sound. Although she was grateful to have her ball returned, she was very unhappy about having the frog return to the palace with her. As promised, however, the princess let the frog eat from her plate and sleep on her feather pillow. Soon the princess began to enjoy the frog's company and feel less lonely. She spoke kind words to him as a friend might speak. One night, she said, "Little frog, thank you for being my friend." She closed her eyes and gave the frog a quick kiss on his warty, cold head. Suddenly—poof!—a light flashed, and a handsome prince stood before her. He said, "My dear princess, I have been under the spell of a sorcerer for over a year and forced to live in the body of a frog. Your kiss has broken the spell! Thank you!" The princess fell in love with the prince and lived happily ever after. The Frog's Tale Why would I want to be a princeand wear a heavy crown,when I can wriggle in the mud so cool and thick and brown? (5)Why smooch with all the princesses and give them golden rings,or ride in pumpkin chariotsand buy a lot of things?A frog's life is far richer than (10)all that could ever before here I'm safe and comfortable—and ooze and slime are free.I wouldn't trade the life I have for any princely thing;(15)I'll stay here where my castle is—since in this pond I'm king!

Mr. Baker's lower elementary class has been discussing story elements such as problem and resolution, main events, and moral. Mr. Baker selects a fable called The Curious Monkey, which follows, to demonstrate some of these elements. However, Mr. Baker soon discovers that the fable poses some challenges for meeting his instructional goals. A long time ago, the first dog to ever live on earth was sleeping peacefully under a large tree in a forest. Lying comfortably on its side, it was content to sleep and sleep. A monkey came upon the sleeping dog and stared at it in wonder. He gathered some of the other animals to show them. "Look at this strange new creature! What is it?" he asked. The giraffe bent her long neck to get a better look. "It is neither giraffe nor okapi." Next, a mouse scurried up and sniffed at the sleeping dog. "It is too big to be a mouse, and it smells different." The other animals each took a turn, but none of them could name the peculiar beast. All the while, in the tree above, the sloth listened silently, smiling. Because he moved so slowly, the sloth was a great observer and therefore knew everything there was to know of the animals in the forest. He finally spoke up. "I think that 'Dog' is the best name for this creature." At the sound of his name, the dog awoke. "What is going on!?" the dog growled angrily. "Who woke me?" The dog barked and bared his sharp teeth, and the animals ran away in fear. The smart, old sloth was safe, knowing the dog could not climb the tree. "You cannot get me," he said, laughing. "But from now on, the animals will flee from you and you will have to chase them." To this day, when dogs are not sleeping, they chase other animals. That evening, all the animals could hear the monkey's new song: "Now you know why you let a sleeping dog lie." One student in the class asks Mr. Baker, "What does 'all the while' mean? I feel like the time keeps changing in the story and it's confusing." Which of the following graphics would best represent how the phrase "All the while" and other sequence phrases signal the order of events in the story? A. (straight line) a long time ago > next > All the while > At the sound of his name > to this day B. (straight line) a long time ago > [all the while (next > at the sound of his name)] > to this day C. (angled line, peak at "at the sound...") a long time ago > next > All the while > At the sound of his name > to this day D. (circle) a long time ago > next > All the while > At the sound of his name > to this day

B. (straight line) a long time ago > [all the while (next > at the sound of his name)] > to this day

Questions 6-8 refer to the following scenario. Mr. Finnegan is reading the following short story excerpt with his class. The excerpt is about a young boy who tries to steal an older woman's purse late at night. The woman, Mrs. Jones, fights back and drags the boy back to her house to clean him up and feed him. The excerpt takes place at the woman's small apartment. The woman was sitting on the day bed. After a while she said, "I were young once and I wanted things I could not get." There was another long pause. The boy's mouth opened. Then he frowned, not knowing he frowned. The woman said, "Um-hum! You thought I was going to say but, didn't you? You thought I was going to say, but I didn't snatch people's pocketbooks. Well, I wasn't going to say that." Pause. Silence. "I have done things, too, which I would not tell you, son—neither tell God, if He didn't already know.Everybody's got something in common. So you set down while I fix us something to eat. You might run that comb through your hair so you will look presentable." In another corner of the room behind a screen was a gas plate and an icebox. Mrs. Jones got up and went behind the screen. The woman did not watch the boy to see if he was going to run now, nor did she watch her purse, which she left behind her on the day bed. But the boy took care to sit on the far side of the room where he thought she could easily see him out of the corner of her eye if she wanted to.He did not trust the woman not to trust him. And he did not want to be mistrusted now. Mr. Finnegan recognizes that his students might be unfamiliar with the terms "gas plate" and "icebox." Which of the following sentences from the excerpt best provides a general context that could be helpful in understanding the meaning of the terms? A."'I have done things, too, which I would not tell you, son—neither tell God, if He didn't already know.'" B."'So you set down while I fix us something to eat.'" C."Mrs. Jones got up and went behind the screen." D."But the boy took care to sit on the far side of the room where he thought she could easily see him out of the corner of her eye if she wanted to."

B."'So you set down while I fix us something to eat.'"

A teacher has students read the following background text about guajira music and the excerpt from a memoir by Alma Flor Ada. Background Text Cuban music is unique because it reflects both the rich history of its homeland as well as influences from many cultures around the world. Early Cuban music was born through the union of African and Spanish music. As the music evolved, it picked up influences from other cultures, including French, North American, and Jamaican. One type of Cuban music is musica guajira, which translates to "country music" in Cuban Spanish. At the time the first guajira music emerged, rural life was often extremely difficult, and poverty and injustice were present; this came through in the music. Guajira music can be played in a minor key, reflecting these hardships, or in a major key, reflecting joy and hope—but it is always peaceful in style. It is often played on the guitar although it can be played on many types of acoustic instruments. Finally, it has poetic, rhyming lyrics that usually describe the beauty of the Cuban countryside and the splendor of the rural Cuban people. Memoir Excerpt Since the accident, there had been no accordion music at night. Now that the bandages had come off, the nightly silence felt even more oppressive to me. I began to go to the river with Samoné to help him bring in the grass. Before, whenever we had spent time together, he had told me stories about bright rabbits and nasty foxes. Yet now all that I heard from him were heavy sighs. It was as though the purpose in his life had left him, drained out through the hand he could no longer use. Then Samoné began to disappear in the afternoons. No one knew where he went. Nobody said much about it, but I could see worried looks on my mother's face when he began to skip dinner too. Sometimes, when he was gone, I felt as though I heard an echo of his music. Then one night, when I was already in bed, I did hear it. Somewhat tentative, and not as bright as it had been before, but there it was: the beautiful sound of a guajira, a gentle love song from the Cuban countryside. Samoné, practicing tenaciously in solitude, had found a way to create music again. I jumped out of bed, tiptoed into the dining room, and looked out into the courtyard. There he was, poised somewhat awkwardly on his taburete, opening and closing the accordion with his knees while he played the keys with his left hand. Yet the music sounded soft and clear, accompanied by Samoné's familiar hum, while the rays of moonlight, filtering through the branches of the flame trees, shone upon the smile that lit his face. —Alma Flor Ada, from Where the Flame Trees Bloom Which of the highlighted lines in the background text helps clarify the change in tone expressed in the line in the memoir excerpt, "Somewhat tentative, and not as bright as it had been before, but there it was: the beautiful sound of a guajira, a gentle love song from the Cuban countryside"?

A teacher has students read the following background text about guajira music and the excerpt from a memoir by Alma Flor Ada. Background Text Cuban music is unique because it reflects both the rich history of its homeland as well as influences from many cultures around the world. Early Cuban music was born through the union of African and Spanish music. As the music evolved, it picked up influences from other cultures, including French, North American, and Jamaican. One type of Cuban music is musica guajira, which translates to "country music" in Cuban Spanish. At the time the first guajira music emerged, rural life was often extremely difficult, and poverty and injustice were present; this came through in the music. Guajira music can be played in a minor key, reflecting these hardships, or in a major key, reflecting joy and hope—but it is always peaceful in style. It is often played on the guitar although it can be played on many types of acoustic instruments. Finally, it has poetic, rhyming lyrics that usually describe the beauty of the Cuban countryside and the splendor of the rural Cuban people. Memoir Excerpt Since the accident, there had been no accordion music at night. Now that the bandages had come off, the nightly silence felt even more oppressive to me. I began to go to the river with Samoné to help him bring in the grass. Before, whenever we had spent time together, he had told me stories about bright rabbits and nasty foxes. Yet now all that I heard from him were heavy sighs. It was as though the purpose in his life had left him, drained out through the hand he could no longer use. Then Samoné began to disappear in the afternoons. No one knew where he went. Nobody said much about it, but I could see worried looks on my mother's face when he began to skip dinner too. Sometimes, when he was gone, I felt as though I heard an echo of his music. Then one night, when I was already in bed, I did hear it. Somewhat tentative, and not as bright as it had been before, but there it was: the beautiful sound of a guajira, a gentle love song from the Cuban countryside. Samoné, practicing tenaciously in solitude, had found a way to create music again. I jumped out of bed, tiptoed into the dining room, and looked out into the courtyard. There he was, poised somewhat awkwardly on his taburete, opening and closing the accordion with his knees while he played the keys with his left hand. Yet the music sounded soft and clear, accompanied by Samoné's familiar hum, while the rays of moonlight, filtering through the branches of the flame trees, shone upon the smile that lit his face. —Alma Flor Ada, from Where the Flame Trees Bloom Before having students read either the background text or the memoir excerpt, the teacher wants to assign a prompt that helps engage students with some of the big ideas of the memoir excerpt by connecting with their personal experiences. Which of the following writing prompts best meets the goal? A.Describe your favorite kind of music. Why is it your favorite? B.What is your special talent or favorite hobby?

The Frog Prince Once upon a time, there lived a beautiful princess with shiny hair. She was the only daughter of a king.Sometimes that meant she was lonely, but the king tried to keep her happy by giving her all that she asked for. After all, he was richer than anyone else in the kingdom. he even gave her a glistening golden ball. she loved to bounce it through the castle's gardens, running after it all the way. One day, she bounced the ball too hard, and it got away from her and dropped into a well. she began to cry. Suddenly, a large, brown, wart-covered frog hopped out of the well and smiled at her. In a croaky voice, he asked, "Why are you crying, princess?" "Oh, I have dropped my golden ball into the well, and I fear I shall never get it back!" she told him. The ugly frog reassured her, "My dear, I can help you get your ball, but if I do, you must be my friend and let me eat things from your plate and stay beside you." "Me? Be your friend?" The princess wrinkled her nose at this idea, but she doubted he would be successful, so she agreed. At once, the frog dove into the well and returned with her golden ball, safe and sound. Although she was grateful to have her ball returned, she was very unhappy about having the frog return to the palace with her. As promised, however, the princess let the frog eat from her plate and sleep on her feather pillow. Soon the princess began to enjoy the frog's company and feel less lonely. She spoke kind words to him as a friend might speak. One night, she said, "Little frog, thank you for being my friend." She closed her eyes and gave the frog a quick kiss on his warty, cold head. Suddenly—poof!—a light flashed, and a handsome prince stood before her. He said, "My dear princess, I have been under the spell of a sorcerer for over a year and forced to live in the body of a frog. Your kiss has broken the spell! Thank you!" The princess fell in love with the prince and lived happily ever after.

Questions 1-3 refer to the following scenario. A teacher is planning a lesson in which students will read and discuss the following passage. Because people are becoming better educated about how they can make a difference through a few simple steps, individuals and communities are making positive changes to the environment. Many groups are working to repair damage to ecosystems. Some of the ways they are doing this are by planting new trees, creating new wetlands, and building parks over closed landfills. This process is called habitat restoration. People are also polluting less. For example, cars now have special devices on their tailpipes. These devices reduce the harmful gases that escape into the air. Although they are still contributors to pollution, factories now release fewer chemicals, and they are not allowed to dump wastes into rivers and streams. Because they understand that adding chemicals to fields and lawns degrades the health of many habitats, many people now use natural ways to get rid of weeds and insects. Also, after gaining an understanding of how reusing products reduces our overall imprint on the environment, people are recycling paper, glass, metal, and plastic more often. And now that more people are recycling, less energy is being used to make new products, less coal is burned, and finally less pollution is added to the environment. The passage primarily follows which of the following text structures? A.Sequential B.Descriptive C.Cause and effect D.Compare and contrast

C.Cause and effect

Questions 11-16 refer to the following scenario. A teacher is reading and discussing the following article with students. Amazing Sea Lions When we scuba dive off the California coast, we often meet playful sea lions. They sneak up behind us, swim circles around us, and perform loops, spins, and somersaults. Then they hang motionless upside down, staring at us as if daring us to try the same tricks. We can only stare back at them in amazement. How do they do that? And without using the scuba tanks, masks, and wet suits that we need to swim underwater? The answer lies in the fact that sea lions' bodies—inside and out—are suited for their diving lifestyle. A combination of features—from their shape to their broad, flat flippers to what is in their blood—allows them to thrive in their underwater world. No Scuba Tanks Sea lions don't need scuba tanks because, in a way, they carry their own oxygen supply with them. Sea lions have more blood than we do. And their blood contains more hemoglobin, which is a protein that carries oxygen to wherever it is needed in the body. Sea lions also have a large amount of myoglobin, another protein that carries oxygen through muscles. So sea lions can store lots of oxygen in their blood and muscles. They don't have to depend only on the air in their lungs for oxygen during their dives. When they dive, sea lions make good use of this oxygen by conserving their energy. They actually lower their metabolism underwater. Their hearts beat more slowly, and any functions that are not needed for diving, such as digestion, slow down or stop. Another energy-saving feature is the shape of sea lions' bodies, which is streamlined and sleek. Their long, smooth shape helps them glide easily through the water so they use less energy while swimming. No Wet Suits Sea lions stay warm underwater because they have a layer of fat called blubber around their bodies. They don't need the wet suits that scuba divers wear to keep from getting cold. The blubber also smooths and rounds out their bodies, which helps streamline their shape. No Masks or Flashlights Scuba divers have to wear face masks in order to see underwater. They also sometimes use flashlights to help them see clearly. But sea lions can see well underwater, even when it's dark. Their large, sensitive eyes have more photoreceptor cells than human eyes do. These cells capture light so that the images of things a sea lion sees can be sent to its brain. These extra cells allow sea lions' eyes to work well in faint light where it would be too dim for us to see anything. Face masks also keep divers from breathing in water. How do sea lions keep water out of their noses while swimming in the ocean? Their nostrils are closed underwater. This is the normal, relaxed position for them. Unlike humans, sea lions have to think about opening up their nostrils to breathe. Growing Up Diving Sea lion mothers come ashore in large groups to have their pups. The pups are born in early summer, usually between May and July. In a matter of weeks, the pups are exploring the water. Within a few months, they are in the ocean, playing and diving together. Using their strong front flippers, they speed through the water. Their flexible backbones allow them to twist and twirl, performing fantastic underwater acrobatics. Sea lions are incredible creatures. Their bodies allow them to dive with ease and freedom. Human divers will never achieve their grace or skill in the water, but we can enjoy watching them! A student writes the following summary of the section called "No Scuba Tanks." (1) Sea lions have more blood than we do. (2) Their blood contains a lot of oxygen. (3) They can store a lot of blood and oxygen in their muscles so they can breathe underwater. (4) The shape of their bodies helps them move easily through the water. Which of the following sentences from the student summary reflects a misunderstanding about sea lions that can be clarified through careful reading of the passage?

Questions 11-16 refer to the following scenario. A teacher is reading and discussing the following article with students. Amazing Sea Lions When we scuba dive off the California coast, we often meet playful sea lions. They sneak up behind us, swim circles around us, and perform loops, spins, and somersaults. Then they hang motionless upside down, staring at us as if daring us to try the same tricks. We can only stare back at them in amazement. How do they do that? And without using the scuba tanks, masks, and wet suits that we need to swim underwater? The answer lies in the fact that sea lions' bodies—inside and out—are suited for their diving lifestyle. A combination of features—from their shape to their broad, flat flippers to what is in their blood—allows them to thrive in their underwater world. No Scuba Tanks Sea lions don't need scuba tanks because, in a way, they carry their own oxygen supply with them. Sea lions have more blood than we do. And their blood contains more hemoglobin, which is a protein that carries oxygen to wherever it is needed in the body. Sea lions also have a large amount of myoglobin, another protein that carries oxygen through muscles. So sea lions can store lots of oxygen in their blood and muscles. They don't have to depend only on the air in their lungs for oxygen during their dives. When they dive, sea lions make good use of this oxygen by conserving their energy. They actually lower their metabolism underwater. Their hearts beat more slowly, and any functions that are not needed for diving, such as digestion, slow down or stop. Another energy-saving feature is the shape of sea lions' bodies, which is streamlined and sleek. Their long, smooth shape helps them glide easily through the water so they use less energy while swimming. No Wet Suits Sea lions stay warm underwater because they have a layer of fat called blubber around their bodies. They don't need the wet suits that scuba divers wear to keep from getting cold. The blubber also smooths and rounds out their bodies, which helps streamline their shape. No Masks or Flashlights Scuba divers have to wear face masks in order to see underwater. They also sometimes use flashlights to help them see clearly. But sea lions can see well underwater, even when it's dark. Their large, sensitive eyes have more photoreceptor cells than human eyes do. These cells capture light so that the images of things a sea lion sees can be sent to its brain.

Sea lions are incredible creatures. Their bodies allow them to dive with ease and freedom. Human divers will never achieve their grace or skill in the water, but we can enjoy watching them! During a conversation about the "No Masks or Flashlights" section, the teacher asks students, "Why can sea lions see in the dark better than humans can?" Which of the following student responses demonstrate an accurate reading of the text? Select all that apply. A.They have built-in face masks like the ones that scuba divers wear. B.Their eyes can make more photo cells when they're in the light. C.They have more cells that send pictures to the brain.

The following is an excerpt of a transcript from a class discussion that took place after students read an informational text about deforestation. Teacher: To what extent do the costs of deforestation outweigh the benefits? Erin? Erin: Well, I think, in my mind, people shouldn't cut down the trees in the rain forests. It might help us get things we need, like paper and wood, but the article said how animals are becoming extinct because they have no place to live. And I feel sorry for the animals, so really it's a bad idea. Teacher: Excellent. What do you think, Tim? Tim: We shouldn't cut down the rain forests. Teacher: OK. Doug? Doug: It's harmful for humans because we read that part about how the machines they use to cut down the trees create air pollution. Teacher: Right, the machinery contributes to carbon emissions. Excellent. Cane? Cane: But cars pollute the air, too. It's kind of the same thing. Plus, we need to get wood from somewhere, or else how can we make new buildings? Teacher: James? James: Well, I guess we can plant new trees to get more wood. But even if we plant new trees after we cut down parts of the rain forest, it takes forever for them to grow. So pretty much, the trees won't grow in time for other generations to use them. Kelly: Maybe people who cut down the trees are just thinking about what they need right now. But they aren't thinking about the future. . . like, the long-term effects. Which three students make a connection to a peer's idea? A.Erin B.Tim C.Doug D.Cane E.James F.Kelly

D.Cane E.James F.Kelly

An upper-elementary school teacher has paired the following version of "The Frog Prince" fairy tale and the related poem "The Frog's Tale" for students to read and analyze. The Frog Prince Once upon a time, there lived a beautiful princess with shiny hair. She was the only daughter of a king.Sometimes that meant she was lonely, but the king tried to keep her happy by giving her all that she asked for. After all, he was richer than anyone else in the kingdom. he even gave her a glistening golden ball. she loved to bounce it through the castle's gardens, running after it all the way. One day, she bounced the ball too hard, and it got away from her and dropped into a well. she began to cry. Suddenly, a large, brown, wart-covered frog hopped out of the well and smiled at her. In a croaky voice, he asked, "Why are you crying, princess?" "Oh, I have dropped my golden ball into the well, and I fear I shall never get it back!" she told him. The ugly frog reassured her, "My dear, I can help you get your ball, but if I do, you must be my friend and let me eat things from your plate and stay beside you." "Me? Be your friend?" The princess wrinkled her nose at this idea, but she doubted he would be successful, so she agreed. At once, the frog dove into the well and returned with her golden ball, safe and sound. Although she was grateful to have her ball returned, she was very unhappy about having the frog return to the palace with her.

Mr. Baker's lower elementary class has been discussing story elements such as problem and resolution, main events, and moral. Mr. Baker selects a fable called The Curious Monkey, which follows, to demonstrate some of these elements. However, Mr. Baker soon discovers that the fable poses some challenges for meeting his instructional goals. A long time ago, the first dog to ever live on earth was sleeping peacefully under a large tree in a forest. Lying comfortably on its side, it was content to sleep and sleep. A monkey came upon the sleeping dog and stared at it in wonder. He gathered some of the other animals to show them. "Look at this strange new creature! What is it?" he asked. The giraffe bent her long neck to get a better look. "It is neither giraffe nor okapi." Next, a mouse scurried up and sniffed at the sleeping dog. "It is too big to be a mouse, and it smells different." The other animals each took a turn, but none of them could name the peculiar beast. All the while, in the tree above, the sloth listened silently, smiling. Because he moved so slowly, the sloth was a great observer and therefore knew everything there was to know of the animals in the forest. He finally spoke up. "I think that 'Dog' is the best name for this creature." At the sound of his name, the dog awoke. "What is going on!?" the dog growled angrily. "Who woke me?" The dog barked and bared his sharp teeth, and the animals ran away in fear. The smart, old sloth was safe, knowing the dog could not climb the tree. "You cannot get me," he said, laughing. "But from now on, the animals will flee from you and you will have to chase them." To this day, when dogs are not sleeping, they chase other animals. That evening, all the animals could hear the monkey's new song: "Now you know why you let a sleeping dog lie." During a discussion about the moral of the fable, one student says, "Morals need to be things like 'keep trying' and 'be kind to others.' 'Let a sleeping dog lie' isn't a moral." Which of the following aspects of the story is most likely causing the student's confusion? A.The moral is stated only at the end of the story. B.The moral is not stated by the wisest character. C.The moral is demonstrated through the personification of animals. D.The moral is written in figurative language.

D.The moral is written in figurative language.

Which of the following word problems can be represented by the equation 4×n+8=16? A.A set of 5 baskets holds a total of 16 apples. The first basket has 8 apples and the other baskets each hold an equal number of apples. How many apples are in each of the other baskets? B.There are 12 baskets, 8 of which are empty. There are 16 apples, with an equal number of apples in each of the other 4 baskets. How many apples are in each of the 4 baskets? C.There are 16 baskets, 8 of which are empty. Each of the other baskets contains 4 apples. How many apples are there in all? D.There are 8 baskets with 4 apples in each basket and 16 apples that are not in a basket. How many apples are there in all?

Option (A) is correct. If there are 5 baskets and one basket holds 8 apples, the rest of the apples are split evenly among the other 4 baskets. Therefore, to find the number of apples in each of the 4 baskets, the equation 4×n+8=16 can be set up, where n is the number of apples in each of the 4 baskets. The problem in option (B) can be represented by the equation 4×n+8×0=16, the problem in option (C) can be represented by the equation 4×(16−8)=n, and the problem in option (D) can be represented by the equation 8×4+16=n

A.The bulletin board has a width of 48 inches. B.The bulletin board has a length of 96 inches. C.The area of the bulletin board is twice the area of the message board. D.The perimeter of the bulletin board is four times the perimeter of the message board.

Option (A) is correct. Since the message board has a length of 30 inches and a perimeter of 108 inches, the width of the message board can be found by solving the equation2(30)+2w=1082(30)+2w=108 for w. To solve the equation for w, subtract 60 from both sides of the equation and then divide both sides of the equation by 2 to find that w=24w=24. This means that the length and width of the bulletin board are 60 inches and 48 inches, respectively, and it can be concluded that the area of the message board is 720 square inches, the perimeter of the bulletin board is 216 inches, and the area of the bulletin board is 2,880 square inches. Thus, the only true statement is that the bulletin board has a width of 48 inches.

Ms. Garrett has been working on verbal counting with her students. She wants them to be more aware of patterns in the way number names are typically constructed. Which of the following number names LEAST reflects the typical pattern in the way number names are constructed in the base ten system? A.Eleven B.Sixteen C.Twenty-five D.Ninety

Option (A) is correct. The number name "eleven" does not follow any pattern of number-name construction with reference to the tens and ones. Option (C) is not correct because "twenty-five" follows the most typical structure of how number names are constructed for whole numbers, since the number of tens in the number is referred to first, followed by the number of ones. Although the numbers in options (B) and (D) do not follow the most typical structure like "twenty-five" does, where the tens are called out specifically, the numbers in these options do follow a structure of the number of ones being named, followed by "teen," which refers to the ten in the number. Therefore, these numbers follow a pattern, unlike "eleven."

Mr. Walters asked his students to order 89, 708, 37, and 93 from least to greatest, and to be ready to explain the process they used to order the numbers. One student, Brianna, ordered the numbers correctly, and when Mr. Walters asked her to explain her process, she said, "The numbers 89, 37, and 93 are less than 100, so they are all less than 708, since that is greater than 100. Also, 37 is the least because it comes before 50 and the other two numbers are close to 100. Then 89 is less than 90, but 93 is greater than 90." Which of the following best describes the strategy on which Brianna's explanation is based? A.A counting strategy B.A benchmarking strategy C.An estimation strategy D.A place-value strategy

Option (B) is correct. Brianna first indicates that 708 is the greatest number because it is greater than 100, while 37, 89, and 93 are all less than 100. Next, Brianna indicates that 37 is the least number because it is less than 50, while 89 and 93 are greater than 50. Finally, Brianna recognizes that 89 is less than 93 because 89 is less than 90, while 93 is greater than 90. Thus, over the course of her explanation, Brianna used 100, then 50, and then 90 as points of reference for comparisons, which is exactly what benchmark numbers are—points of reference for comparison. Brianna did not count between any of the numbers, estimate the numbers, or use the place values in any of the numbers to make her comparisons, so the other options do not describe the strategy on which Brianna's explanation is based.

Ms. Roderick asked her lunch helper in her kindergarten class to get one paper plate for each student in the class. Which of the following counting tasks assesses the same mathematical counting work as this task? A.Having students line up according to the number of the day of the month in which they were born B.Showing students 10 pencils and asking them to get enough erasers for all the pencils C.Showing students a row of 12 buttons and asking them to make a pile of 8 buttons D.Asking students to count the number of triangles printed on the classroom rug

Option (B) is correct. Getting one paper plate for each student in the class assesses whether students can determine when the number of objects in one set is equal to the number of objects in another set, and the task described in option (B) involves a similar determination. The task in option (A) assesses whether students can compare and order numbers. The task in option (C) assesses whether students can count a subset of objects from a larger set. The task in option (D) assesses whether students can count the number of objects in a set.

Ms. Simeone is working with her first-grade students on writing two-digit numerals. She wants to use an activity to assess whether her students are attending to the left-to-right directionality of the number system. Which of the following activities is best aligned with Ms. Simeone's purpose? A.Asking students to read the numbers 20 through 29 B.Asking students to represent the numbers 35 and 53 using base-ten blocks C.Asking students how many tens and how many ones are in the number 33 D.Showing students 23 cubes and 32 cubes and asking them which quantity is greater

Option (B) is correct. Having the students represent 35 and 53 using base-ten blocks will help Ms. Simeone assess whether students know which place is the tens place and which place is the ones place or whether students have reversed the ones place and the tens place, thinking the ones place is on the left and the tens place is on the right. Representing the numbers provides more information about students' understanding of place value than just reading numbers.

In word problems that have a multiplicative comparison problem structure, two different sets are compared, and one of the sets consists of multiple copies of the other set. Which of the following best illustrates a word problem that has a multiplicative comparison problem structure? A.There are 4 shelves in Joaquin's bookcase, and there are 28 books on each shelf. How many books are in Joaquin's bookcase? B.Marcus drives 3 times as many miles to get to work as Hannah does. Hannah drives 16 miles to get to work. How many miles does Marcus drive to get to work? C.A football field is 360 feet long and 160 feet wide. A soccer field is 300 feet long and 150 feet wide. The area of the football field is how many square feet greater than the area of the soccer field? D.An ice cream parlor sells 29 different flavors of ice cream and 4 different types of cones. How many different combinations consisting of an ice cream flavor and a type of cone are available at the ice cream parlor?

Option (B) is correct. In the problem in option (B), the two values being compared are the number of miles that Marcus drives to get to work and the number of miles that Hannah drives to get to work, and the number of miles that Marcus drives is 3 times the number of miles that Hannah drives. The problem in option (A) has an equal-groups problem structure, the problem in option (C) has a product-of-measures problem structure (since the product is a different type of unit from the factors in the problem), and the problem in option (D) has a combinations problem structure.

The scenario in a word problem states that an office supply store sells pens in packages of 12 and pencils in packages of 20. Which of the following questions about the scenario involves finding a common multiple of 12 and 20 ? A.In one package each of pens and pencils, what is the ratio of pens to pencils? B.How many packages of pens and how many packages of pencils are needed to have the same number of pens as pencils? C.If the store sells 4 packages each of pens and pencils, what is the total number of pens and pencils sold in the packages altogether? D.How many gift sets can be made from one package each of pens and pencils if there are the same number of pens in each set, the same number of pencils in each set, and all the pens and pencils are used?

Option (B) is correct. The least common multiple of 12 and 20 is 60, and 5 packages of pens and 3 packages of pencils are needed to have 60 of each writing utensil. The question in option (A) uses factors, not multiples, since 12 pens/20 pencils=3/5. The question in option (C) is best answered by calculating 4×12+4×20=48+80=128, which does not involve finding either a common factor or a common multiple of 12 and 20. The question in option (D) is best answered by finding that the greatest common factor of 12 and 20 is 4, which means that 4 gift sets can be made, each containing 3 pens and 5 pencils.

1/3=3/9=6/18 1/4=4/16=3/12 Ms. White's students are working on generating equivalent fractions like the ones shown. She asks her students to write a set of instructions for how to generate equivalent fractions. One student writes, "You have to multiply the bottom and the top of the fraction by a number." Which of the following revisions most improves the student statement in terms of validity and generalizability? A.You have to multiply both denominator and numerator by the same number. B.You have to multiply both denominator and numerator by the same nonzero number. C.You have to multiply both denominator and numerator by the same whole number. D.You have to multiply both denominator and numerator by the same positive whole number

Option (B) is correct. To generate an equivalent fraction, it is not necessary to multiply the numerator and denominator of the original fraction by a whole number, but it is necessary to multiply the numerator and the denominator by the same number and for that number to be a number other than zero. The revision in option (B) is the only sentence that restates the student conjecture, makes it valid, and generalizes it by including all fractions.

Ms. Rodriguez is working with her kindergarten students to develop the skill of counting on. Which of the following tasks is best aligned with the goal of having students count on? A.The teacher gives each student a number book with a different number on each page. The students must count out and glue the same number of pictures to match the given number on each page. B.The teacher gives each student a 10-piece puzzle, disassembled with a single number written on each piece. The students must put the puzzle together with the numbers in order. C.The teacher gives each student a shuffled deck of 10 cards, each with a single number from 1 to 10. When the students draw a number card, they must count to 20, starting from the number on the card they drew. D.The teacher gives each student 8 blocks and a number cube, with the sides of the number cube numbered from 3 to 8. When the students roll the number cube, they must count out the same number of blocks as the number rolled and create a tower with that number of blocks.

Option (C) is correct. A student would begin with the number drawn and count on from that number until 20 is reached. For example, if the student draws a card with 15 on it, the student would count on from 15, saying, "15, 16, 17, 18, 19, 20." The other tasks described do not require students to count on.

One of Mr. Spilker's students, Vanessa, incorrectly answered the addition problem 457+138 as represented in the work shown. + 457 138 ------- 585 Mr. Spilker wants to give Vanessa another problem to check whether she misunderstands the standard addition algorithm or whether she simply made a careless error. Which of the following problems will be most useful for Mr. Spilker's purpose? A.784+214 B.555+134 C.394+182 D.871+225

Option (C) is correct. In the work shown, after adding the ones and recording the 5 in the ones place, Vanessa did not record that the additional 10 ones were 1 ten, nor did she add the regrouped ten in the tens place. The problem in option (C) will be most useful for Mr. Spilker's purpose because it requires regrouping from the tens place to the hundreds place. The problems in options (A) and (B) do not require any regrouping, and Vanessa may just record 10 hundreds without thinking about regrouping when answering the problem in option (D).

Ms. Duchamp asked her students to write explanations of how they found the answer to the problem 24×15. One student, Sergio, wrote, "I did 24 times 10 and got 240, then I did 24 times 5 and that's the same as 12 times 10 or 120, and then I put together 240 and 120 and got 360." Ms. Duchamp noticed that four other students found the same answer to the problem but explained their strategies differently. Which of the following student explanations uses reasoning that is most mathematically similar to Sergio's reasoning? A.Since 24 is the same as 12 times 2 and 15 is the same as 5 times 3, I did 12 times 5 and got 60, then I did 2 times 3 and got 6, and 60 times 6 is 360. B.To get 24 times 5, I did 20 times 5 and 4 times 5, which is 120 altogether, and then I needed 3 of that, and 120 times 3 is 360. C.15 times 20 is the same as 30 times 10, and that gave me 300, and then I did 15 times 4 to get 60, and 300 plus 60 is 360. D.24 divided by 2 is 12, and 15 times 2 is 30, so 24 times 15 is the same as 12 times 30, and so my answer is 360.

Option (C) is correct. Sergio first uses the distributive property to think of 24×15 as 24×(10+5), or 24×10+24×5. After Sergio multiplies 24 and 10 to get 240, he multiplies 24 and 5 using a doubling and halving strategy. Since 24=12×2, 24×5=(12×2)×5=12×(2×5)=12×10, so the product of 24 and 5 is equal to the product of 12 and 10, which is 120. The explanation in option (C) also uses the distributive property but in a different way. This student thinks of 24×15 as (20+4)×15, or 20×15+4×15. After the student multiplies 20 and 15, the student uses the doubling and halving strategy to find the product of 4 and 15. Therefore, this explanation uses reasoning that is most mathematically similar to Sergio's reasoning. The explanations in options (A) and (B) do not use the doubling and halving strategy, and the explanation in option (D) does not use the distributive property.

Ms. Carter shows one of her students, Brandon, a set of cubes. She tells Brandon that there are 13 cubes in the set and asks him to take 1 cube away from the set. Ms. Carter then asks Brandon, "How many cubes do you think are in the set now?" Brandon quickly answers, "Twelve." Brandon has demonstrated evidence of understanding which of the following mathematical ideas or skills? A.Using numerals to describe quantities B.Counting with one-to-one correspondence C.Recognizing a small quantity without counting D.Knowing that each previous number name refers to a quantity which is one less

Option (D) is correct. In the scenario, Ms. Carter shows Brandon a set of cubes, explicitly tells him how many cubes are in the set, and asks him to take one cube away from the set. This process allows Ms. Carter to ensure that Brandon knows that there is now one less cube in the set. When Ms. Carter asks how many cubes are in the set after one cube is removed, Brandon readily states, without counting the cubes, that there are 12 cubes. This provides evidence that Brandon knows that 12 is the number name that precedes 13 and that 12 refers to a quantity that is one less than 13; it can also be assumed that Brandon has the same understanding for other whole numbers. Brandon did not use written numerals in the scenario, so option (A) is not correct. Also, Brandon is told how many cubes are in the set, so there is no evidence that he can count with one-to-one correspondence or recognize a small quantity without counting, so options (B) and (C) are not correct.

A student incorrectly answered the problem 305.74×100. The student's answer is represented in the work shown. 305.74×100=305.7400 Which of the following student work samples shows incorrect work that is most similar to the preceding work? A. 246.7×100=2,467 B. 13.05×100=13,500 C. 46.13×10=460.130 D. 94.03×10=94.030

Option (D) is correct. In the work shown, when the student multiplied 305.74 by 100, the student rewrote 305.74 and added two zeros at the end. The work sample that is most similar to this is the sample in option (D), since this sample shows that when the student multiplied 94.03 by 10, the student rewrote 94.03 and added one zero at the end.

Ms. Fisher's students are working on identifying like terms in algebraic expressions. When Ms. Fisher asks them how they know when terms are like terms, one student, Coleman, says, "Like terms have to have the same variable in them." Ms. Fisher wants to use a pair of terms to show Coleman that his description of like terms is incomplete and needs to be refined. Which of the following pairs of terms is best for Ms. Fisher to use for this purpose? A.9d and 5 B.8xy and xy C.5a^4 and 2a^4 D.4h^2 and 7h^3

Option (D) is correct. The best pair of terms for Ms. Fisher's purpose should contain the same variable but should not be like terms. The only option that shows such a pair is option (D), in which the variables are the same but the terms are not like terms because they have different exponents.

A grocery store sells both green grapes and red grapes for a regular price of $2.89 per pound. Nelson buys 1.5 pounds of green grapes and 2.25 pounds of red grapes at the store on a day when the regular price is reduced by $0.75 per pound. Which of the following expressions represents the amount, in dollars, that Nelson will pay for the grapes? A.1.5+2.25×2.89−0.75 B.(1.5+2.25)×2.89−0.75 C.1.5+2.25×(2.89−0.75) D.(1.5+2.25)×(2.89−0.75)

Option (D) is correct. To find the amount, in dollars, that Nelson will pay for the grapes, the total weight of the grapes, in pounds, needs to be multiplied by the reduced price of the grapes, in dollars. The total weight of the grapes, in pounds, is 1.5+2.251.5+2.25, and the reduced price of the grapes, in dollars, is 2.89−0.752.89−0.75, so the amount, in dollars, that Nelson will pay for the grapes is (1.5+2.25)×(2.89−0.75)(1.5+2.25)×(2.89−0.75). The parentheses must be included in the expression as shown so that the total weight of the grapes will be multiplied by the reduced price of the grapes.

Ms. Vargas asked her students to write an expression equivalent to 4(x−y). After substituting some values for x and y, a student named Andrew rewrote the expression as 4x−y. Andrew's expression is not equivalent to 4(x−y), but he thought his work was correct based on the substitutions he tried. For which of the following integer values of x and y would Andrew's expression appear to be correct? Select two choices. A.x=0 and y=0 B.x=0 and y≠0 C.x≠0x and y=0 D.x≠0 and x=y E.x≠0 and x=−y

Options (A) and (C) are correct. Since 4(x−y)=4x−4y the expression 4(x−y) is equivalent to 4x−y only when 4y=y, and 4y=y only when y=0. The only options where y=0 are options (A) and (C).

Mr. Varela asked his students to define a square in terms of other two-dimensional geometric figures. Which two of the following student definitions precisely define a square? A.A square is a rectangle that has 4 sides of equal length. B.A square is a parallelogram that has 4 angles of equal measure. C.A square is a parallelogram that has 4 sides of equal length. D.A square is a rhombus that is also a rectangle. E.A square is a rectangle that is not a rhombus.

Options (A) and (D) are correct. A square is a quadrilateral with 4 sides of equal length and 4 angles of equal measure, whereas a rectangle is a quadrilateral with 4 angles of equal measure, a rhombus is a quadrilateral with 4 sides of equal length, and a parallelogram is a quadrilateral where opposite sides are parallel. Therefore, a rectangle that has 4 sides of equal length is a square, and a rhombus that is also a rectangle is a square, so options (A) and (D) are both precise definitions of a square. Option (B) describes a rectangle that is not necessarily a square, option (C) describes a rhombus that is not necessarily a square, and option (E) describes a rectangle that is not a square.

Which three of the following word problems can be represented by a division equation that has an unknown quotient? A.Ms. Bronson works the same number of hours each day. After 8 days of work, she had worked 32 hours. How many hours does Ms. Bronson work each day? B.Mr. Kanagaki put tape around 6 windows before painting a room. He used 7 feet of tape for each window. How many feet of tape did he use? C.Micah used the same number of sheets of paper in each of 5 notebooks. He used 45 sheets of paper in all. How many sheets of paper did Micah use in each notebook? D.Each shelf in a school supply store has 8 packs of markers on it. Each pack has 12 markers in it. How many markers are on each shelf in the store? E.Trina gave each of 7 friends an equal number of beads to use to make a bracelet. She gave the friends a total of 63 beads. How many beads did she give to each friend?

Options (A), (C), and (E) are correct. The word problem in option (A) can be represented by the equation 32÷8=□32÷8=□, the word problem in option (C) can be represented by the equation 45÷5=□45÷5=□, and the word problem in option (E) can be represented by the equation 63÷7=□63÷7=□. The word problem in option (B) can be represented by the equation7×6=□7×6=□ or the equation □÷6=7□÷6=7, and the word problem in option (D) can be represented by the equation 12×8=□12×8=□ or the equation □÷8=12□÷8=12; however, neither of these word problems can be represented by a division equation that has an unknown quotient.

Mr. French's students are working on finding numbers less than 100 that are multiples of given one-digit numbers. When Mr. French asks them how they know when a number is a multiple of 6, one student, Crystal, says, "Even numbers are multiples of 6!" Mr. French wants to use two numbers to show Crystal that her description of multiples of 6 is incomplete and needs to be refined. Which of the following numbers are best for Mr. French to use for this purpose? Select two numbers. A.15 B.16 C.20 D.24 E.27 F.30

Options (B) and (C) are correct. The best numbers for Mr. French's purpose are even numbers that are not multiples of 6, and 16 and 20 are both even numbers, but they are not multiples of 6. Options (A) and (E) are incorrect because 15 and 27 are not even numbers, and options (D) and (F) are incorrect because 24 and 30 are both multiples of 6.

Mr. Benner places a row of 5 cubes on a student's desk and asks the student, Chanel, how many cubes are on the desk. As Chanel points at the cubes one by one from left to right, she counts, saying, "One, two, three, four, five." Then she says, "There are five cubes!" Mr. Benner then asks Chanel to pick up the third cube in the row. As Chanel points at three cubes one by one from left to right, she counts, saying, "One, two, three." She stops, then picks up the three cubes, and gives them to Mr. Benner. Chanel has demonstrated evidence of understanding which two of the following mathematical ideas or skills? A.Using numerals to describe quantities B.Recognizing a small quantity by sight C.Counting out a particular quantity from a larger set D.Understanding that the last word count indicates the amount of objects in the set E.Understanding that ordinal numbers refer to the position of an object in an ordered set

Options (C) and (D) are correct. Chanel first counts the cubes one by one and then she states that there are 5 cubes. Her work demonstrates that she understands that when counting a set of objects, the last word count indicates the cardinality of the set (that is, the number of objects in the set), so option (D) is correct. When she is asked to pick the third cube in the row, she is able to count and stop at three, thus demonstrating that she can count out a quantity from a larger set, so option (C) is correct. However, since she does not pick up the third cube counted, but instead picks up the three cubes she counted, she shows that she does not yet understand that the ordinal number "third" refers to the position of third counted cube, which means that option (E) is incorrect. Also, Chanel does not demonstrate the ability to recognize a small quantity by sight since she counts one by one, so option (B) is incorrect. Finally, she is not asked to record the numeral that describes the number of cubes on her desk, so there is no evidence that Chanel can use numerals to describe quantities, which means that option (A) is incorrect.

An upper-elementary school teacher has paired the following version of "The Frog Prince" fairy tale and the related poem "The Frog's Tale" for students to read and analyze. The Frog Prince Once upon a time, there lived a beautiful princess with shiny hair. She was the only daughter of a king.Sometimes that meant she was lonely, but the king tried to keep her happy by giving her all that she asked for. After all, he was richer than anyone else in the kingdom. he even gave her a glistening golden ball. she loved to bounce it through the castle's gardens, running after it all the way. One day, she bounced the ball too hard, and it got away from her and dropped into a well. she began to cry. Suddenly, a large, brown, wart-covered frog hopped out of the well and smiled at her. In a croaky voice, he asked, "Why are you crying, princess?" "Oh, I have dropped my golden ball into the well, and I fear I shall never get it back!" she told him. The ugly frog reassured her, "My dear, I can help you get your ball, but if I do, you must be my friend and let me eat things from your plate and stay beside you." "Me? Be your friend?" The princess wrinkled her nose at this idea, but she doubted he would be successful, so she agreed. At once, the frog dove into the well and returned with her golden ball, safe and sound. Although she was grateful to have her ball returned, she was very unhappy about having the frog return to the palace with her. As promised, however, the princess let the frog eat from her plate and sleep on her feather pillow. Soon the princess began to enjoy the frog's company and feel less lonely. She spoke kind words to him as a friend might speak. One night, she said, "Little frog, thank you for being my friend." She closed her eyes and gave the frog a quick kiss on his warty, cold head. Suddenly—poof!—a light flashed, and a handsome prince stood before her. He said, "My dear princess, I have been under the spell of a sorcerer for over a year and forced to live in the body of a frog. Your kiss has broken the spell! Thank you!" The princess fell in love with the prince and lived happily ever after. The Frog's Tale Why would I want to be a princeand wear a heavy crown,when I can wriggle in the mud so cool and thick and brown? (5)Why smooch with all the princesses and give them golden rings,or ride in pumpkin chariotsand buy a lot of things?A frog's life is far richer than (10)all that could ever before here I'm safe and comfortable—and ooze and slime are free.I wouldn't trade the life I have for any princely thing;(15)I'll stay here where my castle is—since in this pond I'm king! Part A The teacher wants the class to focus on how the princess changes in the fairy tale. Which of the following student statements most accurately describes her change? A."The princess was stuck-up at the beginning, but she became open-minded by the end." B."The princess was clumsy at the beginning, but she became careful by the end." C."The princess was shy at the beginning, but she became confident by the end." D."The princess was cautious at the beginning, but she became adventurous by the end." Part B Of the six highlighted sections of "Frog Prince," which two, when viewed together, best illustrate the change in the princess? A."She was the only daughter of a king." B."One day, she bounced the ball too hard, and it got away from her and dropped into a well." C."'Oh, I have dropped my golden ball into the well, and I fear I shall never get it back!' she told him." D."'Me? Be your friend?'" E."She spoke kind words to him as a friend might speak."

Part A A."The princess was stuck-up at the beginning, but she became open-minded by the end." Part B D."'Me? Be your friend?'" E."She spoke kind words to him as a friend might speak."

Questions 6-8 refer to the following scenario. Mr. Finnegan is reading the following short story excerpt with his class. The excerpt is about a young boy who tries to steal an older woman's purse late at night. The woman, Mrs. Jones, fights back and drags the boy back to her house to clean him up and feed him. The excerpt takes place at the woman's small apartment. The woman was sitting on the day bed. After a while she said, "I were young once and I wanted things I could not get." There was another long pause. The boy's mouth opened. Then he frowned, not knowing he frowned. The woman said, "Um-hum! You thought I was going to say but, didn't you? You thought I was going to say, but I didn't snatch people's pocketbooks. Well, I wasn't going to say that." Pause. Silence. "I have done things, too, which I would not tell you, son—neither tell God, if He didn't already know. Everybody's got something in common. So you set down while I fix us something to eat. You might run that comb through your hair so you will look presentable." In another corner of the room behind a screen was a gas plate and an icebox. Mrs. Jones got up and went behind the screen. The woman did not watch the boy to see if he was going to run now, nor did she watch her purse, which she left behind her on the day bed. But the boy took care to sit on the far side of the room where he thought she could easily see him out of the corner of her eye if she wanted to. He did not trust the woman not to trust him. And he did not want to be mistrusted now. Part A Which of the following pairs of adjectives best describes Mrs. Jones? A.Cynical, careless B.Empathetic, maternal C.Kind, vain D.Wistful, gullible Part B Which two of the following pieces of evidence best support the correct answer to Part A? A."The woman said, 'Um-hum! You thought I was going to say but, didn't you?'" B."'Everybody's got something in common.'" C."'You might run that comb through your hair so you will look presentable.'" D."Mrs. Jones got up and went behind the screen." E."The woman did not watch the boy to see if he was going to run now, nor did she watch her purse, which she left behind her on the day bed."

Part A B.Empathetic, maternal Part B B."'Everybody's got something in common.'" C."'You might run that comb through your hair so you will look presentable.'"

A chef at a restaurant uses 1/5 liter of lemon juice and 3/10 liter of teriyaki sauce to make a marinade for 2 kilograms of salmon. How many liters of marinade does the chef use per kilogram of salmon? Give your answer as a fraction.

The correct answer is 1/4. The chef uses 1/5+3/10=2/10+3/10=5/10=1/2 liter of marinade for 2 kilograms of salmon. This means that the chef uses 1/2 // 2=1/4 liter of marinade per kilogram of salmon.

Joshua walks the length of each of three trails on a hike. The first trail is 3.6 kilometers long. The second trail is 3.7 kilometers long. The third trail is 600 meters shorter than the sum of the lengths of the first two trails. Joshua walks at an average speed of 3 kilometers per hour over the course of the entire hike. How many minutes does it take Joshua to complete his hike?

The correct answer is 280 minutes. Since 600 meters is equivalent to 0.6 kilometers, the third trail is 3.6+3.7−0.6=6.7 kilometers long. Therefore, Joshua walked a total distance of 3.6+3.7+6.7=14 kilometers on his hike. Since Joshua walks at an average speed of 3 kilometers per hour and there are 60 minutes in an hour, the proportion 3 kilometers/60 minutes=14 kilometers/x minutes can be used to find how many minutes it takes Joshua to complete his hike. Based on the proportion, 3x=(14)(60), and since (14)(60)=840, x=840/3=280, which means that it takes Joshua 280 minutes to complete his hike.

Questions 11-16 refer to the following scenario. A teacher is reading and discussing the following article with students. Amazing Sea Lions When we scuba dive off the California coast, we often meet playful sea lions. They sneak up behind us, swim circles around us, and perform loops, spins, and somersaults. Then they hang motionless upside down, staring at us as if daring us to try the same tricks. We can only stare back at them in amazement. How do they do that? And without using the scuba tanks, masks, and wet suits that we need to swim underwater? The answer lies in the fact that sea lions' bodies—inside and out—are suited for their diving lifestyle. A combination of features—from their shape to their broad, flat flippers to what is in their blood—allows them to thrive in their underwater world. No Scuba Tanks Sea lions don't need scuba tanks because, in a way, they carry their own oxygen supply with them. Sea lions have more blood than we do. And their blood contains more hemoglobin, which is a protein that carries oxygen to wherever it is needed in the body. Sea lions also have a large amount of myoglobin, another protein that carries oxygen through muscles. So sea lions can store lots of oxygen in their blood and muscles. They don't have to depend only on the air in their lungs for oxygen during their dives. When they dive, sea lions make good use of this oxygen by conserving their energy. They actually lower their metabolism underwater. Their hearts beat more slowly, and any functions that are not needed for diving, such as digestion, slow down or stop. Another energy-saving feature is the shape of sea lions' bodies, which is streamlined and sleek. Their long, smooth shape helps them glide easily through the water so they use less energy while swimming. No Wet Suits Sea lions stay warm underwater because they have a layer of fat called blubber around their bodies. They don't need the wet suits that scuba divers wear to keep from getting cold. The blubber also smooths and rounds out their bodies, which helps streamline their shape. No Masks or Flashlights Scuba divers have to wear face masks in order to see underwater. They also sometimes use flashlights to help them see clearly. But sea lions can see well underwater, even when it's dark. Their large, sensitive eyes have more photoreceptor cells than human eyes do. These cells capture light so that the images of things a sea lion sees can be sent to its brain. These extra cells allow sea lions' eyes to work well in faint light where it would be too dim for us to see anything. Face masks also keep divers from breathing in water. How do sea lions keep water out of their noses while swimming in the ocean? Their nostrils are closed underwater. This is the normal, relaxed position for them. Unlike humans, sea lions have to think about opening up their nostrils to breathe. Growing Up Diving Sea lion mothers come ashore in large groups to have their pups. The pups are born in early summer, usually between May and July. In a matter of weeks, the pups are exploring the water. Within a few months, they are in the ocean, playing and diving together. Using their strong front flippers, they speed through the water. Their flexible backbones allow them to twist and twirl, performing fantastic underwater acrobatics. Sea lions are incredible creatures. Their bodies allow them to dive with ease and freedom. Human divers will never achieve their grace or skill in the water, but we can enjoy watching them! The teacher gathers the following graphics to supplement instruction with the article. Graphic 1: The Anatomy of the Sea Lion Graphic 2: Growth of pup to Sea Lion Graphic 3: Oxygen Flow in the Seas Lion Of the three graphics, the teacher would like to select one graphic to support students' understanding of the main ideas in the article and one graphic to support their understanding of a complex process described in the article. Next to each goal, type the number of the graphic that would best fit the goal. To support understanding of the main ideas, use: 1, 2, or 3 To support understanding of a complex process use: 1, 2, or 3

To support understanding of the main ideas, use: 1 To support understanding of a complex process use: 3

Questions 1-3 refer to the following scenario. A teacher is planning a lesson in which students will read and discuss the following passage. Because people are becoming better educated about how they can make a difference through a few simple steps, individuals and communities are making positive changes to the environment. Many groups are working to repair damage to ecosystems. Some of the ways they are doing this are by planting new trees, creating new wetlands, and building parks over closed landfills. This process is called habitat restoration. People are also polluting less. For example, cars now have special devices on their tailpipes. These devices reduce the harmful gases that escape into the air. Although they are still contributors to pollution, factories now release fewer chemicals, and they are not allowed to dump wastes into rivers and streams. Because they understand that adding chemicals to fields and lawns degrades the health of many habitats, many people now use natural ways to get rid of weeds and insects. Also, after gaining an understanding of how reusing products reduces our overall imprint on the environment, people are recycling paper, glass, metal, and plastic more often. And now that more people are recycling, less energy is being used to make new products, less coal is burned, and finally less pollution is added to the environment. The first paragraph provides which of the following context clues to help students understand the meaning of "habitat restoration"? Select all that apply. A. A definition B. A contrast C. Examples

a. a defintion c. examples
