A kindergarten teacher brings a basket of apples for a class snack. They have 16 students but
brought only 8 apples. The teacher first places the apples on a table and asks the students to each
take 1. When the teacher observes that there are too few apples, they tell the students to stand in
pirs behind the apples. The teacher then cuts the apples in half and puts the halves side by side on
the table. The teacher asks the students if there are now enough apple pieces for everyone to take
one piece. Finally, the teacher asks the students to observe and discuss why there are now enough
apple pieces for everyone. Which of the following mathematical concepts is the teacher
demonstrating at snack time?
A. symmetry
B. spatial sense
C. additive identity
D. proportional thinking Correct Ans-D. proportional thinking
Third-grade students notice that multiplying the number 2 by 3 by 5 gives the same answer as
multiplying 5 by 2 by 3. This realization by students represents an opportunity for the teacher to
make the point that:
A. using the communitive property of multiplication can make mental computations simpler.
B. identifying and extending number patterns can help in problem solving
C. identifying functional relationships can help problem solving
D. using the associative property of multiplication can make mental computations simpler
Correct Ans-A. using the communitive property of multiplication can make mental
computations simpler.
, There are 20 hamsters, 9 kittens, and 6 puppies at a pet store. How many more kittens are at the
pet store than puppies?
First-grade students are learning to solve word problems involving addition and subtraction. For
the problem shown, the teacher finds that some of the students have subtracted combinations of
20, 9, and 6. Which of the following interventions would help these students determine an
appropriate solution to this problem?
A. asking students to write a number sentence that models the problem using a symbol such as a
star to represent the unknown
B. providing students with opportunities to identify unneeded information in the problem and
explain why it is irrelevant
C. explicitly teaching strategies for effective counting to improve retrieval of arithmetic facts
D. encouraging students to use a number line as a visual aid for understanding the operations of
addition and subtraction Correct Ans-B. providing students with opportunities to identify
unneeded information in the problem and explain why it is irrelevant
Which of the following examples best describes how societal and cultural values can affect the
development and use of science and technology?
A. collaboration among scientists to develop an innovative product
B. use of traditional knowledge of plants to create home remedies
C. promotion of a new software tool to analyze data at an international science conference
D. growth and selling of genetically modified foods in the United States while other countries
Correct Ans-D. growth and selling of genetically modified foods in the United States while
other countries
Giving students time to design their own investigation rather than following an activity out of a
textbook on that topic can be beneficial because it:
