These are great for math centers! There are 11 different even and odd fidget spinner game boards included. Includes 1, 2, 3, and 4 digit numbers. Students will spin the fidget spinner and which every problem they land on they need to solve. If they get it right they can make a tally mark on their side with their dry erase marker. You will need to laminate the boards and purchase fidget spinners. Mark one end of it with a sticker or paint. I use paint so it is more permanent.
