Mixed Addition and Subtraction Worksheets
These mixed worksheets combine addition and subtraction problems on the same page, requiring kids to check the operation sign before solving each one. They're a strong review tool for 1st through 3rd graders who already know both operations separately, and each printable PDF includes an answer key.

How to teach switching flexibly between addition and subtraction
- 1
Circle the operation sign first
Before solving anything, have your child go down the page circling every plus and minus sign so they commit to the correct operation up front.
- 2
Sort problems by type
For extra support, have them separate the page into an addition pile and a subtraction pile mentally before working through it top to bottom.
- 3
Estimate before solving
Ask whether the answer should be bigger or smaller than the starting number, which catches accidental operation-switch mistakes immediately.
- 4
Rotate strategies as needed
Remind them they can use counting on for addition and counting back or borrowing for subtraction within the very same worksheet.
Common mistakes kids make
- Adding when the sign says subtract, or vice versa, out of habit from the last problem — the circle-the-sign step directly fixes this.
- Rushing through the page at one steady rhythm and missing sign changes — encourage a brief pause between each problem.
- Forgetting borrowing steps when a subtraction problem appears among easier addition ones — treat every subtraction problem with the same careful column check.
- Skipping problems that look harder — remind them mixed practice is meant to build flexibility, not just speed.
Tips for parents and teachers
- This format is excellent for spiral review, keeping recently learned skills sharp instead of forgotten.
- Use it as a weekly math warm-up to keep both operations fresh throughout the school year.
- Watch for a pattern of errors on one operation specifically, which tells you where to focus extra practice.
- Time the sheet occasionally to build confidence switching between operations quickly.
