Vending machine reward chart. As a reward, you place the quarters on the reward chart. When its filled up the student gets to go to the vending machine to choose a treat. This is a very big motivating reward to be able to purchase from the machine that is normally for teachers only. Another option would be to have a "vending machine" treasure box with candy etc. Print the file and cut on the dotted line, laminate if desired. Cut out the quarters and add velcro to both sets of quarters.
