These are great for math centers! There are 6 different money fidget spinner game boards included. 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. You will also need bags with fake money.
