Sara is regarded by her fourth-grade classmates as the best reader because she reads aloud very quickly. Why might you need to provide corrective feedback to Sara?

Fluency is as much about expression as it is about speed. Answer Explanation : Fluency includes the melody of speech, the rises and falls that convey shades of meaning to the words being spoken, and reading with expression. When a student reads too quickly, it is not apparent that the student actually understands what she is reading. Choice C is not necessarily correct, and Sara's automaticity (ability to identify words effortlessly) is not an issue as she is reading quickly.

Read the following passage:Sneezing and coughing, Grace felt warm and her head hurt. School would be no fun today, she thought.Which of the following choices is a fact-based inference?

Grace is sick. Answer Explanation : The reader can infer from these statements that Grace is sick. Although choices B, C, and D could be correct, the passage doesn't provide any factual basis for them. However, it is directly stated that Grace is sneezing and coughing, her head hurts, and she feels warm all over—all facts supporting that she is sick.

Histogram Answer Explanation : Histograms act as a type of sorting "bin." You have one variable, and you sort data by this variable by placing them into bins. Then you count how many pieces of data are in each bin. In a histogram, the bins are always a range of numerical values that have no overlap. The other answer choices are not suitable for particulars within a category.

What is one of the first things that young students need to learn in order to read any text?

How print moves across and down the page Answer Explanation : By the time students arrive in kindergarten, they should already be familiar with how English print moves from left to right and top to bottom on a page. Familiarity with print is critical for students in order for the rest of reading instruction to make sense.

Calculate 12,690 ÷ 23.5.

540 Answer Explanation : 12,690 ÷ 23.5 = 540. When dividing decimals by hand, move the decimal in the divisor (23.5) to the right until it is a whole number. In this case, that is one place. Move the decimal the same number of places in the dividend, so that the division problem is now 126,900 ÷ 235. Then divide as you normally would.

Jonah Miller takes home $3,000 a month from his teaching job. According to the following budget how much does he pay each month in rent? Rent is 25%

$750 Answer Explanation : First look at the budget to find out what fraction of his earnings goes to his rent. Using mental math, rather than pencil and paper, cut $3,000 in half to get 50% which gives you $1,500. Then cut that in half again to get 25% of the budget; half of $1,500 is $750.

Solve the following system of linear equations. 4 x + y = 24 2x - 3y = -2

(5,4) Answer Explanation : There is more than one way for solving this system by substitution. One way is to first solve for y (from 4x + y = 24) to find that y = 24 ? 4x. Substitute 24 ? 4 x for y in 2x ? 3y =-2 to get 2x ? 3(24 ? 4x)=-2. From there: 2x ? 3(24 ? 4 x) =-2 2x ? 72 + 12 x = -2 14 x ? 72 =-2 14 x = 70 x = 5 Then substitute 5 for x in either equation to find that y = 4. The ordered pair where the two lines intersect is therefore (5, 4).

In conducting a poll on the popularity of a Democratic City Council member, which sample set would produce the most accurate results?

1,000 registered voters chosen at random Answer Explanation : Choices A and B, only Democrats or only Republicans, would be biased samples. A sample set of only 10 people is too small to give valid results. Choosing 1,000 registered voters at random and calling them would give the best results as it provides a large enough random sample to yield valid results.

What is 25% of 250,000?

62,500 Answer Explanation : To find the percent of a number, change the percent into a decimal (0.25) and multiply it by the other number: 250,000(0.25) = 62,500. Or to find 25% of a number, just divide that number by 4.

What is the mode for the given data set? 12, 91, 103, 51, 7, 12, 77, 82, 112, 91, 63, 107, 12, 34

12 Answer Explanation : The mode is the number that occurs most often in a data set. There can be more than one mode if multiple pieces of data occur in the set the maximum number of times. There is no mode if all the data appear in the set the same number of times.

Consider the number sequence below. 1, 8, 3, 10, 5, 12, 7, 14, 9, ... What will the twelfth number in this sequence be?

Write the number 219 in scientific notation.

2.19 x 10^2 Answer Explanation : To convert the number 219 into scientific notation, first move the decimal to write it as a number between 1 and 10. In this case, 219 becomes 2.19. In order to get back to a value of 219, 2.19 would have to be multiplied by 100. In scientific notation, the second number is always written as a power of 10. 100 is equivalent to 102. Finally, combine the two parts to write 219 as 2.19 x 102 in scientific notation.

A rainbow Answer Explanation : Rainbows are created when sunlight rays pass through water. The arc of colors is caused by the refraction, or bending of light. Students learn about rainbows at an early age. By second or third grade, students will likely be able to explain what causes a rainbow.

Read the following poem: I met a traveler from an antique land Who said: Two vast and trunkless legs of stone Stand in the desert .

Allusion Answer Explanation : In using the name of a Pharoah, the author is alluding to the power and majesty of the Egyptian culture, as well as eventual downfall and relegation of that empire to ancient history. While the sonnet does employ other answer choices, the use of Ozymandias is a classic example of using allusion to evoke images of power, empire, and the transitory nature of both.

x-bar chart

Answer Explanation : When two dice are rolled, the sums that occur most often are the ones closest to the middle because there are more combinations to make those sums. For example, there are 6 different ways to make a sum of 7 on two dice, which means that 7 is theoretically the most likely sum to roll. On the other end of the spectrum, there is only one way to get a sum of 2 and one way to get a sum of 12.

Read the following sentence: Washington, D.C. is the capital of America, but Austin is the capital of Texas. Which of the following best describes the type of sentence above?

Involving the librarian may be helpful, but only after the teacher has assessed the student's interests.

If the dimensions of a rectangle are doubled, what happens to its area?

It increases by a factor of 4 Answer Explanation : The area of a rectangle is length times width, and when the sides are doubled, it is ( 2l ) times ( 2w ). After multiplying those values together, the answer is 4 lw. Any time all the dimensions are doubled in a shape, the area quadruples.

What is the process of non-reproductive cell division called?

Mitosis Answer Explanation : Mitosis is the process of nuclear division in living cells by which chromosomes are exactly replicated and the copies distributed to identical daughter nuclei. In mitosis, a parent cell divides into two identical daughter cells with a full set of chromosomes. Meiosis only occurs with sperm cells and egg cells, so that there are half the chromosomes in them. This allows sperm and egg cells to join for reproduction and have a full complement of chromosomes.

"Twentieth-century America," "in a small hotel room," and "the dead of night" are all examples of which literary element?

Which of the following formulas can help your students know how much fat to eat each day, given that each fat gram carries 9 calories and about 30% of a child's daily calories should be from fat?

Multiply total daily calories by 30%, (e.g., 1800 x 0.30 = 540 fat calories/day). Divide fat calories by 9 to get fat grams, (e.g., 540 / 9 = 60 fat grams/day). Answer Explanation : Students would need to calculate how many fat calories per day to consume, and then convert fat calories into fat grams since that is what is labeled on food packaging. Choice D makes the error of beginning with fat calories per week and then forgetting to divide by 7 to get to the amount per day.

A second grade science experiment involves the dyeing of flowers based on the hypothesis that flowers will change colors when food dye is mixed with the water that is feeding them. One student suggests trying all three different colors separately instead of one. Is adding more colors a way to make this experiment any more valid?

No, the experiment is about whether it is possible to change colors. Answer Explanation : Adding colors would not make the experiment more scientifically valid. The experiment is merely to discover whether it is a possibility to change a flower's color with dye. Adding or changing the color would not affect the outcome of the experiment. However, since the hypothesis is about flowers in general, it would be useful to attempt the color experiment on several kinds of flowers.

What is the difference between a vascular and non-vascular plant?

Non-vascular plants do not contain vessels and vascular plants do contain vessels. Answer Explanation : Vascular and non-vascular are the two major divisions of plants. The plants in both groups contain chlorophyll, the molecule that absorbs sunlight. The difference between the two categories of plants is that the vascular varieties contain vessels which allow them to produce flowers. Non-vascular plants, by definition, do not contain vessels.

In scientific experimental design, which of the following predicts that the independent variable will not have an effect on the dependent variable, as a means of eliminating bias?

Null hypothesis Answer Explanation : The NULL hypothesis predicts that the independent variable, which is manipulated during the experiment, will not have an effect on the dependent variable, which is what is being measured. The NULL hypothesis is presumed to hold true until experimental results disprove it. At that time, an alternative hypothesis would probably be proposed and tested.

Which of the following reservoirs of carbon contains the largest pool of carbon near the surface of the Earth?

The mantle is a layer of the Earth, and Atlantis is the name of the mythic underwater city.

Which of the following is least likely to be useful in gaining knowledge on a specific scientific topic?

Performing the same experiment multiple times with a different hypothesis Answer Explanation : If the same experiment is performed multiple times, without any change in any of the variables, the same results are likely to occur. Once those results have been recognized, different or varied experiments need to be conducted to learn more. Knowledge can also be gained by reading about prior results, communicating with others, and proving a hypothesis to be true.

This illustration best exemplifies what key scientific concept in data gathering and observation. Target with a small area contacted

Precision Answer Explanation : Precision refers to how close multiple measurements of the same question are to each other. In other words, precision gets at how repeatable an experiment is, since with no changes in variables, the same results should occur. Accuracy is how close to the actual value, represented by the center of the target, an experiment or question obtains.

When items are chosen from a population in such a way that every item in that population has an equal opportunity to be in the sample, this is what kind of sampling?

Random Answer Explanation : A random sample means that all items in the population have the same chance to be a part of the sample. All of the other choices create groups within sample populations, so they do not allow for equal opportunity of all population members.

In reading several magazine articles for a mention of President Clinton, which method would be most effective?

Scanning Answer Explanation : Scanning means looking quickly over a text to locate specific words or groups of words. Skimming is reading quickly to locate general ideas, themes, or main ideas. Both choices C and D would be counter-effective in terms of finding the location quickly.

The Thompson family buys a car for $10,000. They make a down payment of $400 and will pay the rest of the cost of the car in equal monthly payments over the period of 4 years. Assuming that the interest rate on their loan is 8%, what is the first step in determining their monthly payment?

Subtract $400 from $10,000. Answer Explanation : Breaking down complex problems like this one is crucial to arriving at the correct calculations. Before determining monthly payments or the effect of the interest rate, first subtract the family's down payment ($400) from the total cost of the car ($10,000). Only then can you begin making the calculations that determine the family's monthly payment.

Which of the following pieces of background information would be most relevant to reading a non-fiction book about planetary movement in space?

Why is the temperature usually cooler in the mountains?

The atmosphere and the air are thinner in the mountains. Answer Explanation : When the atmosphere is thinner, there are fewer molecules to absorb heat. The air is still made up of the same types of molecules, but they are less densely packed due to decreased atmospheric pressure at higher elevations.

Eric's grandfather passed away, leaving him a collection of bottle caps from the 1970s and a sport utility vehicle. As a memorial to his late grandfather, Eric wants to glue a "racing stripe" of bottle caps all the way around the perimeter of the truck. The bottle caps are about one inch in diameter. The truck is about 7 feet wide and 18 feet long. What, if anything else, is needed to determine whether Eric has enough bottle caps?

The number of bottle caps in the collection Answer Explanation : The number of bottle caps needed would be about 600. In order to determine whether Eric has enough bottle caps, you would need to know how many he has. If the number of caps in the collection exceeds 600, then Eric can tackle this project.

Three Laws of Motion Answer Explanation : Newton was a mathematician, physicist, and one of the foremost intellectuals of modern times. He is responsible for many great discoveries and scientific advances including the invention of the telescope, calculus, and laws of motion and gravity. The First Law of Motion deals with the concept of inertia; the Second Law of Motion explains acceleration; the Third Law of Motion states that every action has an equal and opposite reaction.

After reading a non-fiction text selection to the class, why is it important to summarize the events and ideas contained in the book?

To provide students with a clear explanation of the book's overall themes Answer Explanation : Students benefit from a summary description after a read-aloud. Summarizing not only weaves together what was just read, but it also gives the teacher an opportunity to touch on key points found earlier in the book that may have been forgotten. Additionally, it is an ideal time for students to ask follow-up questions to extend learning.

A performance assessment indicates that a first grade student struggles to recognize grade-level sight words. Which of the following activities is likely to be most beneficial to this student?

Working together using letter manipulatives to build sight words Answer Explanation : Using manipulatives can be helpful in a variety of content areas. In this instance, the movement of letter blocks to build sight words is an effective learning tool for the student given the assessment results. Reading books that deal with high-frequency words would be an appropriate extension activity.

Though the reader may understand that the word "them" refers to the inhabitants of the homeless shelter, those inhabitants are never mentioned.

An object with so much mass that nothing can escape its gravitational field is called a

black hole. Answer Explanation : The misnomer "black hole" is commonly used to refer to these celestial phenomena whose mass is so great that it exceeds the escape velocity of even light. Due to this mass, the object is invisible, or "black." Choices A, B, and C are also deep-space objects, usually observed with the help of radio telescopes (telescopes that "see" relatively long wavelengths).

Water moves between the oceans and lands through the processes of

condensation and evaporation. Answer Explanation : The transformation of a liquid into gaseous form is called evaporation. Conversely, condensation occurs when gas turns into a liquid. The continual cycle between these two processes is the force behind the Earth's water movement

A pair of consonant letters that work together to represent a single consonant sound is called a

consonant digraph. Answer Explanation : Digraphs are pairs of letters that operate together to form a single sound; there are both vowel digraphs and consonant digraphs. Consonant blends such as /ch,/ /th,/ and /sh/ are consonant digraphs that represent a single sound.

Systematic phonics instruction is

explicit in its approach. Answer Explanation : Systematic phonics instruction is clear and organized in its approach to teaching students phonemes. Choice A is incorrect—a digraph does represent a phoneme, but this is not the basis for systematic phonics instruction. Choice B is incorrect because studies have shown that implicit phonics instruction is actually inferior to explicit phonics instruction. Choice D is also incorrect; systematic phonics instruction promotes good spelling in kindergarten and first grade.

In one of the Amelia Bedelia books, Amelia takes out paper and draws a picture of drapes when she is told to "draw the drapes." The word "draw" in this sense is a...

homonym. Answer Explanation : Homonyms have the same sound, but different meanings. A subcategory of homonyms is homographs, which indicates that the two words are spelled the same but have different meanings. Synonyms have the same meaning, antonyms have opposite meaning, and palindromes are spelled the same forwards and backwards.

Leon's parents used to joke that it took five giant storks to deliver him to his parents, and that he weighed fifty pounds a week later. This is an example of...

hyperbole Answer Explanation : Hyperbole is a figure of speech using much exaggeration, though not for deception. It is highly unlikely that it took five storks to deliver Leon to his parents, since we know that is not how children arrive in the world, and just as unlikely that he weighed fifty pounds a week later. Personification is giving person-like qualities to non-people, either objects or animals.

When demonstrating the use of a solvent in the classroom, the teacher should make sure to store it in?

in a metal cabinet. Answer Explanation : Because solvents pose a fire hazard, they should be stored in a fire-resistant container, such as a metal cabinet. Choice B would not protect students or the classroom from a potential fire. Choices A and D are better options, but would not contain a fire if the solvent evaporated and created the possibility of a fire.

Studies find that fluency instruction based on "repeated reading"

is a better method than silent reading. Answer Explanation : Research indicates that repeated reading improves students' fluency and automaticity. Reading and re-reading texts with the proper feedback also improves word recognition. Choice D is incorrect as round-robin reading usually only allows a particular student to read a small block of text, often only one time during the exercise.

A triangle with two equal sides can best be described as

isosceles Answer Explanation : An isosceles triangle is a triangle with two equal sides. A triangle with all equal sides is an equilateral triangle and a scalene triangle has no sides that are equal. A parallelogram has four sides, so it is not a triangle.

Radio telescopes search for

large wavelengths. Answer Explanation : Radio waves exist toward the large end of the electromagnetic spectrum. In contrast to optical telescopes, which search for light waves (relatively tiny in comparison), radio telescopes can detect quasar, pulsars, and other celestial phenomena in deep space.

Building fluency through classroom practice should include

lengthy, guided oral readings. Answer Explanation : Extensive oral reading is most helpful to students in developing fluency, especially if the teacher is providing corrective feedback. This method also allows the teacher to model fluency (expression, observation of punctuation, speed). Choice A will not offer enough text to each student to promote fluency; choices B and D feature silent readings, which may reinforce fluency but do little to build it.

During a tsunami, people in a boat several miles off shore in deep water may

not notice the event. Answer Explanation : Typically caused by catastrophic undersea events (landslides, earthquake, volcanic activity), tsunamis are characterized by fast-traveling waves, which may not be noticeable offshore. However, when the waves pile up on one another closer to the coastline, they gain height and power. Tsunamis push water miles inland and are one of most destructive of natural disasters.

In a study of exposed strata, you find a thick layer of limestone resting on the bedrock. Which of the following inferences could you logically make, based on that finding' The area had been?

the site of a shallow sea many, many years ago. Answer Explanation : Limestone is sedimentary rock formed from the shells, bones, and waste deposits of sea life. Often, indentations of shells are readily evident in limestone, even without digging.

In a unit on spelling conventions, a teacher chooses to work on the word get before the word gem. This is because

the "g" in get is a more common usage. Answer Explanation : The phoneme /g/ is a more common sound when presented with the grapheme "g;" the /j/ phoneme that begins gem occurs with less frequency. Choice A, while true, would have no bearing on learning about spelling conventions. The same is true of choice C. Choice D is incorrect as get has three phonemes, just like gem.

The literary term "register" refers to

the appropriateness of style for a given work. Answer Explanation : Register refers to the specific language that writers and speakers use for specific situations. For example, a technical medical manual would shy away from slang, and a casual conversation in the elevator would have an informal tone.

The alphabetic principle is best described as

the association of sounds with letters. Answer Explanation : In its most basic form, the alphabetic principle is the idea that there is a systematic correspondence between letters and the sounds of language. Choice A is incorrect (it describes a phoneme), and choice C is incorrect—morphology is the study of word structure.

A quadrilateral with exactly one pair of opposite parallel sides is a

trapezoid Answer Explanation : A trapezoid has exactly one pair of opposite parallel sides. The parallel sides are not the same length. The other two sides cannot be parallel, since they have to connect the sides of unequal length. The other answer choices all have two pairs of parallel sides. Rectangles and rhombuses are types of parallelograms.

In contrast to compound microscopes, stereo microscopes have...

two eyepieces. Answer Explanation : Stereo microscopes use two eyepieces to produce a three-dimensional visualization of the image being studied. Stereo microscopes do not feature any audio component, and actually have a superior depth of field when compared to the more traditional compound microscope.

Which of the following statements is true about the word hungry? It contains

two syllables and six phonemes. Answer Explanation : A phoneme is the atom of the sound world, the smallest unit of sound that can be distinguished from other sounds. There can be multiple phonemes in a single syllable, such as the /h/, /u/, and /n/ in the first syllable of hungry. Sometimes, however, two or more letters may form a single sound, such as the digraph sh, which constitutes only one phoneme, /sh/.

Sounds that consist of a blend of two separate vowel sounds such as /oi/ in oil or /oy/ in toy are

vowel diphthongs. Answer Explanation : A vowel diphthong is a complex sound that slides from one vowel to a second vowel sound in the same syllable. Vowel digraphs are a blend of two separate vowel sounds. Consonant-influenced vowels occur when any vowel letter is followed by a consonant and changes the sound of the preceding vowel.

Hannah is y years old. Write an expression for her age 8 years ago.

y-8 Answer Explanation : The present age of Hannah is y years. To find out how old she was 8 years ago, you must subtract 8 years from her present age, which is y ? 8

What is the equation of the following line? crosses at y=4 and x=4

y= -x+4 Answer Explanation : The line crosses the y-axis at positive 4, so the y-intercept is 4. The slope is -1; slope is the amount of "rise" (vertical change) divided by the "run" (horizontal change). In the form ofy = mx + b where m is the slope and b is the y-intercept, the equation for this line isy = -x + 4.

Which of the following lines is parallel to y=1/2 x +3?

y=1/2 x + 6 Answer Explanation : Parallel lines always have the same slope because they remain the same distance apart forever. Choice A (answer) is the only choice with the same slope as the line in the question.

Based on the triangles below, you can assume the following: AB = DE, AC = DF, and ∠A ≅∠D. Which of the statements below must also be true?

△ACB = △FDE Answer Explanation : The two triangles pictured are congruent. According to the Side-Angle-Side theorem, two triangles are congruent if a pair of corresponding sides and the included angle
