Teaching tips and what to try next

This sheet mixes addition and subtraction, so children must notice the sign before deciding whether to carry or borrow. Have them circle each minus sign first. For focused practice, use Two-Digit Addition With Regrouping and Two-Digit Subtraction With Regrouping.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

This second grade worksheet mixes 10 two-digit addition problems and 10 two-digit subtraction problems, all written in columns under a simple row of leaves, acorns and stars. Every addition problem needs regrouping in the ones place and has a sum under 100. Every subtraction problem needs regrouping too, because the top ones digit is always smaller than the bottom ones digit.

Mixing the two operations on one page is the point. Children have to read each sign before they start, which is a habit that prevents a lot of careless mistakes. Each of the 10 versions has new problems.

How to use it: before your child begins, have them highlight or circle every minus sign. For addition, remind them that 10 ones make a new ten, so they write the extra ten above the tens column. For subtraction, they trade one ten for 10 ones before subtracting the ones. Base-ten blocks or bundles of 10 craft sticks help when a problem feels tricky. A quick check: add the answer to the bottom number of a subtraction problem and you should get the top number.

The answer key shows every answer in red. For more practice, see our 2-Digit Addition With Regrouping and 2-Digit Subtraction With Regrouping worksheets.
