How it works: a quick refresher
The rules this worksheet practices, then one problem worked from start to finish.
| Strategy | How it works |
|---|---|
| Start at the first number | For 4 + 3, put your finger on 4. Don't count the 4 itself. |
| Add: jump forward | Each jump moves one to the right: 5, 6, 7. You land on 7. |
| Subtract: jump back | For 12 − 5, jump left five times: 11, 10, 9, 8, 7. |
| Count the jumps, not the marks | The answer is where you land after the last jump. |
Worked example
Use the number line: 9 + 4.
- 1Start at 9.
- 2Jump forward four times, counting each landing: 10, 11, 12, 13.
- 3You land on 13, so 9 + 4 = 13.

Common questions
- Is there an answer key?
- Yes. Every worksheet has a matching answer key with each answer worked on the same grid or layout as the question. The worksheet code printed at the bottom of each page pairs a sheet with its key.
- My child lands one short. Why?
- They are probably counting the starting number as the first jump. Say the start number, then count only as you jump: "9 ... 10, 11, 12, 13".
- When should my child stop using the number line?
- When they can count on in their head from the bigger number. The line is a bridge to that, not something to drop too early.
- How many different versions are there?
- About a million per skill. Each time you press the button the problems are generated fresh, so you can print a different version for every student, a retake, or another night of practice.
- Are the worksheets free?
- Yes. They are free to print and copy for your home or classroom, with no sign-up.
