Question

Boots walk $9$ blocks from a park to a store, and then home. The total distance walked is $16$ blocks. Identify the image that represents the number of blocks from the store to his home.

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Solution: Option A

Say: Let’s read the question and observe the image.

Ask:
Is this an addition or subtraction problem? Why?
Ans: It is a subtraction problem, because we have the total number of blocks walked, i.e., 16, and the blocks between park and store, i.e., 9. To find out the blocks between the store and home, we have to subtract the above two blocks.

How will you represent the number frame for this problem?
Ans: We have to add 16 counters in two number frames, cross out 9 counters, and count the remaining.

Which option shows the correct number frame, and why?
Ans: Option A, because it has 16 counters, out of which, 9 are crossed out.

How many blocks is it from the store to home?
Ans: 7

What will be the subtraction equation for the problem?
Ans: 16 – 9 = 7

Hence, option A is the correct answer.

WB: If required, use the whiteboard to draw the correct number frame and write the equation.


Error Analysis Question:
Q. All the options other than the correct option, represents a total of 16 blocks. Only the number of blocks crossed out is incorrect. Is that true? Why?
A: No, all the options except option D represents a total of 16 objects. Option D represents 15 objects.

Q. What will be the subtraction equation for this option?
A: The subtraction equation for option D is 15 - 9 = 6.
