How it works: a quick refresher
The rules this worksheet practices, then one problem worked from start to finish.
| Strategy | How it works |
|---|---|
| Start with the small numbers | Add two of the smaller numbers and look for the total in the group. |
| The answer is never the biggest | Every group has a number bigger than the answer, so check each one. |
| Cross off as you go | If a number can't be made from two others, put a small line through it. |
| Check the sentence | 2 + 4 = 6 only counts if 2, 4 and 6 are all in the group. |
Worked example
Find the number made from two others: 2, 4, 6 and 9.
- 1Try the two smallest: 2 + 4 = 6.
- 26 is in the group, so circle it.
- 3Check 9 too: 9 − 2 = 7, 9 − 4 = 5 and 9 − 6 = 3. There is no 7, 5 or 3, so 9 is not made from two others.
- 4Write 2 + 4 = 6.

- 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.
- Can my child count on fingers?
- Yes. Counting on from the bigger number (4, then 5, 6) is a good strategy at this age. With practice the pairs that make each number start to stick.
