Im a parent and Im not sure Im understanding this question the practice test question says How would you take apart 14 to solve 28 14 The choices are 7 and 710 class=


Answer :

There are several ways of taking apart the number 14:

1 and 13

2 and 12

3 and 11

4 and 10

5 and 9

6 and 8

7 and 7

Nevertheless, as we can see by the note below that exercise,

"Have your child take apart 16 to make a ten to find 87 - 16",

we can conclude that the exercise is asking how to take apart 14 to make a ten. By doing so, the subtraction operation (28 - 14) gets simpler since you could subtract 4, and then subtract the ten:

14 = 10 + 4 (1 ten and 4 units)

So, when we do 28 - 14, we can do that in two steps:

• 28 - 4 = ,24

,

• 24, - 10 = 14

Therefore, based on the note below exercise 6, the expected answer is

10 and 4
