Center tags with student instructions for 12 different math centers. Very simple to create with common classroom/home items (dice, craft sticks, styrofoam cups, and common math manipulatives. Once materials are gathered and grouped the centers can "run" for several weeks with the supplies. It is easy to add different supplies, same instructions as skills progress. The only manipulative not readily available are the arrow cards, I found those online. Double sided student recording sheets is included.
