Teaching tips and what to try next

Mixing addition and subtraction on one page makes children read each sign instead of doing every problem the same way. Have them circle the minus signs before they start. For focused practice of each operation, use Addition Within 10 and Subtraction Within 10.

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 first grade worksheet mixes 10 addition facts and 10 subtraction facts within 10 under a simple border of leaves, apples, acorns and stars. Every addition fact has two addends of 1 or more and a sum of 10 or less. Every subtraction fact starts at 10 or less and leaves at least 1.

Facts within 10 are the building blocks for everything that comes later, so fluency here pays off for years. Each of the 10 versions has a new set of facts, and together the versions use all 45 addition facts and all 45 subtraction facts.

How to use it: read the sign on each problem out loud before solving it, since the two kinds are mixed. Encourage your child to use facts they know. If they know 6 + 3 = 9, then they also know 9 - 3 = 6 and 9 - 6 = 3. Ten dried beans, ten buttons or a paper ten-frame make good counters for the facts that are still slow. A few minutes a day is plenty, and short daily practice works better than one long session.

The answer key shows every answer in red. For more practice, see our Addition Within 10 and Subtraction Within 10 worksheets, or our Fact Families worksheet.
