Use these worksheets to review subtracting numbers up to 20 using number bonds. Students decompose the big number into the "ten plus" fact, then take from ten and add the parts left together. 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 an addition pack and anchor chart pack available. If you would like all three products, I have a bundled listing as well!
