At my school, we have a positive behavior system called Bear Bucks. When a kid does something good, they get a buck. There are a few parties during the year where they can go if they've earned enough money. But I needed something to serve as an incentive between parties. This, my Bear Buck store!
I got a shoe organizer from Walmart and put it on the back door to my closet. It's filled with little trinkets and various things the kids can "buy". Hopefully it will help them start working towards earning those bucks!
