What's on this sheet

Addition within 10 is usually introduced in kindergarten and mastered in first grade. At this stage children are still connecting numbers to quantities, so a page should feel friendly rather than intimidating: a handful of problems, plenty of writing space, and a reason to finish. Every sheet here uses a themed adventure layout with a mascot cheering your child on.

Why this sheet works

The problems are drawn from every possible sum within 10 and arranged so no fact repeats on a page. If your child needs more practice, one click regenerates a brand-new sheet from the same skill — you will never print the same page twice unless you want to.

How this one works

One question from this sheet, worked through a step at a time.

2 + 8

2+8
2+8=10
  1. 2 + 8. The answer stays under ten, so this is one to count on rather than split into tens.
  2. Start from the bigger one — you may pick, because 2 + 8 and 8 + 2 land in the same place — and count on 2: 9, 10. So 2 + 8 = 10.
