Tips for Parents & Teachers

1

Frame subtraction as "taking away" or "how many are left?" at first — it is the most intuitive interpretation for young children.

2

Connect subtraction to addition: if your child knows 3 + 4 = 7, help them see that 7 - 4 = 3.

3

Use a number line for counting back — it gives subtraction a visual, physical action.

4

Word problems are harder because children must figure out the operation. Practice asking "is this an adding or taking-away situation?"
