Addition Within 20 Worksheets for Kindergarten

Working on it together

Sit with your child for the first few problems, counting the pictures or hopping along the number line. Say each number out loud, such as eight plus seven, before writing the answer. Once your child feels steady, step back and let them work through the rest of the page alone. Check the answer key together at the end.

Adjusting the numbers

If numbers within 20 feel too hard, switch to within 10 and add pictures to count for support. If your child is ready for more, remove the pictures and the ten frame. Let them use the number line alone, or try mixing addition and subtraction on one page. Either change keeps practice matched to what your child needs right now.

Where to go from here

Once addition within 20 feels steady, move to subtraction within the same range using the same picture supports. You can also mix addition and subtraction problems on one page, or try fact families. Fact families show your child how 8 plus 7 and 15 minus 7 are connected. Keep problems close to numbers your child already knows.
