1st grade math review worksheets

This 1st grade math review mixes single-digit addition and subtraction on one printable worksheet. Instead of practising one operation in a long block, children have to notice the symbol, decide whether to add or subtract, and then solve. That small decision makes mixed review useful for checking understanding after each skill has been taught separately.

The starting sheet contains 15 questions and a separate answer key. Change the problem count for a shorter warm-up or a longer independent practice page. Every sheet number creates a repeatable set of questions, while the A–D option produces several versions at the same difficulty for groups, make-up work or repeated practice.

When to use this Grade 1 review

Use the page after students can count on for addition and count back for subtraction. It works as a weekly check, a short homework sheet, a return-from-break refresher or a quick way to find out which operation needs more practice. The preset is guidance rather than a fixed curriculum sequence, so adjust it to match the work your child or class has already covered.

Teaching tips

• Ask the student to circle the plus or minus sign before solving so the operation is chosen deliberately.
• Keep counters, a number line or ten frames nearby when the goal is understanding rather than speed.
• Invite the student to explain one addition and one subtraction answer aloud using a simple story.
• If mixed practice causes many errors, return to a single-operation sheet and combine the skills again later.
• Use the answer key to discuss patterns in mistakes instead of marking only right or wrong.

How to print this worksheet

1. Check the settings above. They are already set for first grade mixed addition and subtraction.
2. Pick 10, 15, 20 or 30 problems, a title, and the name or date lines you want.
3. Choose US Letter or A4 to match the paper in your printer.
4. Press Download PDF for a file you can save and reuse, or Print to send it straight to your printer.
5. Keep the answer key page for yourself. The sheet number in the footer lets you make the exact same sheet again later.

How to adjust the difficulty

Keep one-digit numbers for fact fluency. When those facts are secure, choose two digits and avoid regrouping for a gentle introduction to place-value computation. If a student is not ready for mixed operations, open the dedicated addition or subtraction page from the related worksheets below.
