Select all you think are the roles of the constructivist teacher:
1. Asking questions that would require students to explain and justify: why, what does that tell you? or why not? 2. Focusing on children's thinking rather than on their writing correct answers. 3. Encouraging children to discuss among themselves rather than concentrate on getting right answers and correcting wrong answers.
Mark all that are basic facts.
14-8=6 6*0=0 3+9=12
Many beginning teachers believe that children will automatically memorize basic facts if they just get enough practice. One very effective strategy to help children learn basic facts is the three-step approach. The first step is [ ] . The second step is [ ] . The third step is[].
Answer 1: Understanding the meaning of the operations Answer 2:Using thinking strategies to retrieve facts. Answer 3:Using consolidating activities for drill and practice.
What do we call our system? This ]is the number of objects use in the grouping process. Our system is a [ ] system. Wherever we have 10 or more objects, they may be regrouped to make one group of the next larger place value. there is n one numeral for ten, rather, the number 10 is expressed as 1 ten and 0 ones, or 10. There are ten digits in the [ ] system: 0 through 9.
Base ten system
Kindergarten Students choose, combine, and apply effective strategies for answering quantitative questions, including quickly recognizing the [ ] of small sets of objects, counting and producing sets of given sizes, counting the number of objects in combined sets, or counting the number of objects that remain in a set after some are taken away. Fourth grade KCC 4: Understand the relationship between numbers and quantities; connect counting to [ ].

Compare- difference unknown
True or False:The estimation is not necessarily a legitimate mathematical tool
False
This strategy involves beginning with one addend and counting on the number of the second addend. For example, to solve the problem 6+3, ah child could start with 6 and count forward three times, saying seven, eight, nine.
Counting on
Mark all reasons that children should explore different algorithms.
Different algorithms provide variety in the math class. Different algorithms may help children develop more flexible mathematical thinking and number sense.

T/F According to CCSSM, to add and subtract within 20, you may use several strategies. One strategy is decomposing a number leading to a ten. Its example is "8+6 = 8+2+4 =10+4 = 14."

[ ] is simply saying the numbers in order, usually starting with one, e.g. 1,2,3,4,5 etc. It does not mean counting objects, or counting actions, although it is connected to these skills. It just means saying the numbers in order not connected to anything.
Rote counting
What do we call an instructional approach consistent with vygotsky's ideas for guiding children's learning in mathematics, an approach where the teacher gradually releases the learning responsibility to the children?

Read a description about what a teacher is teaching her students. Have your students stand in a circle. Decide what number you're starting with and what number you're going to skip by.

There are factors contributing to children's difficulties in problem-solving. Which factor does the statement explain? -Statement- Children's out-of-school experiences are varied; therefore, children develop various problem-solving strategies.
Sociocultural factors
Select statements that are not ideal as the teacher's role in problem-solving instruction.
Teach children how to prevent them from making mistakes.Expect specific responses from students.
If students think that there is no relationship between the value of each place,
Then have students describe value of adjacent place values
If students think that numbers with the same digits have the same value (For example, 23 and 32 or 15 and 150)
Then have students model the values with manipulatives then discuss why they have the same numbers in different place values
T/F: When solving division problems such as 56 divided by 5, the phrase "5 goes into 56" should not be used because it has no mathematical meaning.
True
You might ask a child who has displayed five fingers whether she or he could show the same number in another way, such as by drawing a picture of five objects or picking up a group of five blocks. This is called [ ].`

How many pieces of ribbon were there in total? puzzles- Can you join all 9 dots using 4 straight lines without lifting your pencil? application problems- How much does the school board pay for the electricity in the school each year?
T/F: To solve addition and subtraction problems using the base ten blocks, children exchange or trade a rod for ten units rather than "take apart" a rod.
True
T/F:There was an addition problem: Ray has 6 goldfish. But he wants 13. How many more does he need to buy? Corey solved this problem. He said, "Six plus six is twelve, and one plus is seven is thirteen." We can say that he was using derived facts.
True
Estimation strategy- Clustering strategy
When a set of numbers are close in value
Vygotsky describes children's learning as "cultural" where they interact with others, objects, and events in the classroom environment. He adds to this notion that children's ability to solve a problem is affected by a window of opportunity that he labeled as the [ ] or ZPD. The lower limit (A in the diagram below) begins the children's prior knowledge, concepts, and skills and the upper limit (B in the diagram below) is determined by the tasks that can be successfully completed only with step-by-step instruction.
Zone of Proximal Development
divisor

adjusting to easier numbers
The [ ] strategy involves increasing one addend while decreasing the other by the same amount.
compensation
To examine whether a child has this ability, have the child count two sets of the same objects, such as Unifix cubes. One set of, say, 32 cubes is left spread out on the table, while the other set is placed in small transparent plastic glasses in groups of 10. The child is then asked to compare the sets. Children who realizes that both sets have the same number, regardless of their arrangement, are said to be able to have this ability.
conservation of number
One of the most useful strategies for computing a multiplication exercise mentally is to employ the [ ]. For example, 5××76 can be computed as (5××70) + (5××6).
distributive property
If students think that number that look different must have different values (for example, 23 and 1 ten and 13 ones),
have student model two such numbers with manipulatives then discuss why they have the same value but look different.

T/F: A problem like "a gardener has 60 feet of fence to keep animals out of the garden. What is the largest area of garden that this fence will enclose?" may be effective to develop Constructing a Table or Chart.
true
T/F: To help students make better sense of representing numbers, many researchers and teachers have recommended teaching children by beginning from concrete models, pictorial and graphic representation of numbers, and symbolic representation of numbers.
true
T/F: US students exhibit this misconception much more often than students in other countries. It has to do with thinking of the = sign as an operator (the operational view ). Kind of like thinking that = means "to do" the operation. For example, a student with this operational view of the equal sign tends to solve the problem, 7 + 6 = _13_ + 2 True
true
T/F: When children first decode numbers, they are not likely to use the multiplicative term times; rather, they talk about groups. For example, the 2 in 28 is explained as two groups of ten or two tens.
