Addition to 20 Practice Worksheet for First Grade
By Rochelle P.
A worksheet of about 50 addition problems within 20, opening with a ten-frame model that shows how a full ten plus extra ones makes a sum like 10 + 3 = 13. It builds fluency with sums to 20 and gives first graders a steady run of practice that moves from guided visual modeling to independent computation.
Customize for your classroom
Teacher Guide & Tips
- Use this as independent or partner practice after a whole-class lesson on making ten, roughly 15 to 20 minutes per session.
- Discussion question: How does seeing a full ten-frame help you find the total faster than counting every dot one by one?
- Scaffold for struggling readers: Have students draw their own ten-frame beside each problem and circle the first ten before adding the rest.
- Extension for advanced students: Ask them to explain a strategy like 9 + 6 by making a ten first, and to write a related problem for a partner to solve.
- Estimated time: about 20 minutes for the full set of problems, or split the page across two short sessions.
