Use these Addition and Subtraction Posters as a resource and teaching tool for your classroom that is aligned to CCS. The download includes both an addition and subtraction poster at regular slide size (10 x 7.5 inches). It also includes each poster broken up into four slides. Each slide can then be pieced together to make a poster double the size of the original (20 x 15 inches). Both the addition and subtraction posters include a title, definition, labels for the parts of the number sentences, an example problem, and pictures to help aid in student learning. They both are displayed in fun and bright colors with chevron backgrounds. Thanks for the download from Miss Kelly's Classroom! Enjoy!
