Use these worksheets to review adding numbers to 20 using number bonds. Students decompose the small number to make ten and then use their "ten plus..." fact to solve. For example, for 9+4, students would be guided through steps to say "9 + 1 = 10, 10 + 3 = 13". This product aligns with the Common Core Math Standards and also fits in to Module 2 of the Engage NY 1st grade math curriculum. Worksheets can be used a daily practice and as homework.
There is also a subtraction pack and anchor chart pack available. If you would like all three products, I have a bundled listing as well!
