Math question 1

Intro

Jenny and Jill are best friends and they both have 12 blocks each. Jenny’s blocks are green and Jill’s blocks are yellow.

Sample Problem

Solution

Q: How many blocks do they have in total?
A: They BOTH have 12 blocks, so if one of them has 12 blocks, the other has 12 blocks also. 12 x 2 = 24 or 12 + 12 = 24
A: 24

Q2: How many blocks will they have left (in total) if one of them gives away half of their blocks?
A: Together Jenny and Jill have 24 blocks. They each have 12 blocks. Half of 12 is 6. So if only Jenny gives half of her blocks away, she’ll have 6 left. (12/2=6). Jenny will have 6 blocks left, so add Jenny’s remaining blocks with all of Jill’s blocks.
A: Jenny and Jill will have 18 blocks left. (12 + 6 = 18)
