How it works
- Look at the sheet: it mixes sums and differences up to 10 and up to 20.
- Press New sheet for different problems at the same level.
- Print it with the answer key, or let your child solve it on screen.
What the sheet practices
Number facts up to 10, which children should know by heart, and up to 20 without crossing ten, like 12 + 5 and 17 − 4. Missing numbers, like 6 + __ = 9, show how addition and subtraction fit together.
Questions and answers
Can I choose the problems myself?
Yes, the addition and subtraction worksheets let you set the range, regrouping and the number of problems.
Is this the same as Year 1 in the UK?
Not quite: US 1st grade matches Year 2 in England, for children aged 6 to 7.
