These are my addition mats! I have the kiddos turn these to the side and count out counters for each number in the seperate boxes. When they are ready to start adding they move them over to the box after the equal sign. This lets my kiddos count them and move them so they don't end up counting a counter twice or forget which one they were trying to count. Once we get into addition I let them choose they can use them or not use them, but most of my students wanted to use them even when they didn't have to have them.
