About this worksheet
Use it after addition to 10 and subtraction within 10 have each been practised on their own. For grade 1, raise the limit to 20.
Standards
- Common Core K.OA.A.2 — solve addition and subtraction word problems, and add and subtract within 10
- Common Core 1.OA.C.6 (within 20, the next step)
Questions
Are the operations in a pattern?
They alternate: odd-numbered problems add, even-numbered subtract. The numbers are shuffled, so each problem still has to be read.
