Subtract within 10
Take away from numbers up to 10, then find the missing number.
Three levels
One skill, rising difficulty
Each sheet carries one level. The three are the same skill at rising difficulty, each named for what it practises.
- Level 1: Take away from 5 or less
- Subtract.
- Level 2: Take away from 10 or less
- Subtract.
- Level 3: Missing number
- Write the missing number.
Worked example
How the sheet explains it
The helper printed at the top of each sheet: one solved example and the steps a student follows, before the first question. Every number sentence in it is proven by the same checker as the answer key.
Level 1: Take away from 5 or less
5 − 2 = 3
- Start at 5 and count back 2: 4, 3.
- So 5 − 2 = 3.
Level 2: Take away from 10 or less
9 − 6 = 3
- Add up instead. Count up from 6 to 9: 7, 8, 9.
- That is 3 jumps, so 6 + 3 = 9.
- So 9 − 6 = 3.
Level 3: Missing number
8 − 3 = 5
- Start at 8 and count back to 5: 7, 6, 5.
- You took away 3, so 8 − 3 = 5.
- If the first number is missing, add the other two.
