About this chart
Every addition fact from 0 + 0 to 10 + 10, with doubles and make-10 facts colored.
What kids practice
Addition within 20 means putting two groups together when the total is 20 or less. In first grade, kids move from counting every object to faster tricks like counting on, doubles and making ten. Those tricks are what make the bigger facts like 8 + 6 feel easy.
Watch for
- Counting the first number again when counting on, so 8 + 3 becomes 10 instead of 11.
- Counting everything from 1 every time, which is slow and leads to mistakes.
- Forgetting that order does not matter. 2 + 9 is the same as 9 + 2, so start with the bigger number.
It's free to print, as many copies as you need. See the full addition within 20 guide for 1st grade.
