How to use this worksheet
- Write the name and date at the top. The header shows "set no. 101", the same number as on the answer page.
- Work from 1 to 20; the numbering runs across, so 1 and 2 share the first row. Each sum goes on the line after the equals sign.
- Fingers or small objects are fine on the first try; a week later, try the same page without them.
- Check the work with page two, where every problem is repeated with its answer in bold.
What this worksheet teaches
Both numbers in every problem are between 1 and 9, and no sum is larger than 10, so the page stays inside the first ten. Children practice counting on from the larger number (for 2 + 8, start at 8 and say "9, 10") and slowly move from counting to simply remembering. Turnaround pairs such as 6 + 4 and 4 + 6 show that changing the order does not change the sum.
Number bonds to 10
Six of the twenty problems make exactly ten: 8 + 2, 9 + 1, 6 + 4, 2 + 8, 7 + 3 and 4 + 6. These pairs are called number bonds to 10. Knowing them by heart pays off soon: the "make a ten" strategy for bigger sums (8 + 5 = 8 + 2 + 3) is built on them.
