Brownie points are a wonderful way to promote positive behavior for your whole class. Simply laminate and cut out the display cards and brownies along with the mystery reward cards. For added cuteness use a cookie sheet. Attach magnets to the cookie sheet and the laminated brownies. Display the magnetic cookie sheet on your whiteboard. I also use a small canvas bag, which I hot glued the brownie point mystery reward sign on, to hold the mystery rewards. This hangs right next to the cookie sheet on a suction cup hook. The class can earn brownie points by getting a compliment from other teachers, working well in small groups, or any other thing that shows good behavior! Once the class earns the predetermined number of brownie points, draw from the bag for a class reward. The kids go nuts over this! I hope this turns out to be fun for your class.
