I created this math mat for my students as another tool to help teach double digit addition and subtraction. My students are able to notice patterns while moving about on the 120 chart and see relationships between numbers as it breaks down how to move around. It also helps build their mental math abilities. All you have to do is print as many mats as you need and slip into a plastic sheet protector and it's ready to go. I hope you will find this useful in your classroom!
