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.
