About these worksheets
These worksheets introduce students to the foundational concepts of addition. Activities include matching pictures to addition sentences, identifying number pairs that make 10, breaking apart two-digit numbers into tens and ones, and counting up and down within 20. Designed primarily for kindergarten and first grade, these resources help young learners connect visual representations to number sentences and build early number sense before moving on to traditional addition problems.

About these worksheets
When students are ready to add more than two numbers at once, these worksheets provide the practice they need. Activities range from adding three single-digit numbers with sums under 20 to adding three and four two-digit numbers with regrouping. Word problem versions are also included, where students pull key numbers from a story and add multiple three-digit addends. These worksheets align with first through third grade Common Core standards.
