This product contains everything you need to build your own anchor charts for addition and subtraction for numbers up to 20! This set of four posters will address addition and subtraction by using pictures and crossing out to solve, as well as using number bonds and the "take from 10" strategy. 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 are also worksheet packs and homework helper letters available. If you would like all four products, I have a bundled listing as well!
