The Cool Cat's Button Math - Adding and Subtracting 5
Created by Lindsey Powers 2013
For Addition, I recommend printing on colored paper, laminating each slide, and giving students different colored buttons. They can solve one card at a time using their buttons. I would also stick the cards in page protectors so that students can use a white board marker to write their answer in the box.
For subtraction, same as above, but they can also use a white board marker to X out the circles to help them find the difference.
