Picture subtraction, step by step
Subtraction makes sense to a young child as taking things away.
The question
=
10 − 5
••••••••••
••••• ✗✗✗✗✗
••••• ✗✗✗✗✗
10 − 5 =5
- Start with all 10 and take 5 away — cross them off one at a time, and what is LEFT is the answer, not what you crossed.
- 5 crossed off leaves 5 standing.
- 10 − 5 = 5. Counting back from 10 gets there too, and is quicker once the numbers are too big to draw.
