How is this different from a regular addition sheet?

The blank moves around: sometimes the whole is missing, sometimes a part. That mix builds subtraction and missing-number thinking, not just adding.

What numbers do first grade bonds use?

Everything stays within 10, matching the first grade fluency standard. Each print mixes fresh bonds so the practice never repeats.

1st grade number bonds

1st grade number bonds worksheets

In first grade, number bonds become a fluency tool: each bond within 10 is missing its whole or one part, and your child fills it in from memory. Knowing 7 is 5 and 2 without counting is what makes bigger addition feel easy later.

The kind of problems you'll get

Fill each empty part or whole.

The whole is 5. One part is 2. Find the other part.
Answer: 5 minus 2 is 3.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

How to teach this

Say each bond as a fact family: "3 and 5 make 8, so 8 take away 3 is 5." If your child still counts on fingers for a bond, that pair needs a few more days. Circle it and repeat it tomorrow rather than pushing through the page.

Watch for: Kids add the two numbers they can see, even when one is the whole. If the big circle is filled in, the job is to find the missing part. Kids think each whole has only one right split. 10 can be 6 and 4, 7 and 3, or 5 and 5, and seeing many splits is the point.
