Addition within 20 Resources

If your students have mastered adding numbers under 10, move them on up with these resources for adding numbers within 20. These worksheets provide students with plenty of practice adding. There are also several lesson plans to give you ideas for teaching students how to add numbers within 20. If students struggle, you may want to review our addition within 10 lesson plans.

Accessible Addition Within 20 Resources

The need to calculate simple equations often comes up in day-to-day life—exchanging money, following recipes and determining elapsed time are a few common examples. The addition within 20 resources housed in the Learning Library caters to kids who start to dip into two-digit math.

The printable worksheets provide assorted assignments that sharpen this skill. Kids can practice finding the sum with traditional vertical and horizontal equations. There are also many addition-within-20 word problem printouts. Some of the worksheets are illustrative, like with spaceships or rainbow fish, to deliver visual and creative math lessons.

Hands-on activities help students refine what they have learned in the classroom. A creative game called Pocket Math includes the whole family. Everyone has to wear as many pockets as possible and young learners practice counting them all up. Bowling for Addition turns a DIY bowling game into a counting opportunity. The water bottle pins are marked with a value that students add up once the pins are knocked down.

Kids continue to build their counting capabilities with the online games, guided lessons, printable workbooks, interactive stories and other addition within 20 resources in the library.
