Grade 1 Subtraction Worksheets — Within 10
Free & unlimitedNo loginAnswer key includedCCSS 1.OA.6
Subtraction within 10 is the mirror of addition within 10 — and the place where “think addition” becomes a strategy: to solve 9 − 6, a fluent student asks “6 plus what makes 9?”. Every problem on these sheets keeps results at zero or above, so there are no confusing negative answers.
The generator balances the drill across the whole within-10 space, including the subtract-zero and subtract-all facts students often see too rarely.

Frequently asked questions
- Why does my first grader find subtraction harder than addition?
- Counting backwards is genuinely harder than counting on. Teach “think addition” (6 + ? = 9) and fact families so subtraction reuses what they already know.
- Do these worksheets ever produce negative answers?
- No. The generator only builds problems where the first number is greater than or equal to the second.
