In the behavior world, we call sticker charts "token economies." Token economies are where children can earn tokens for identified "good" behavior, and after earning a pre-determined amount, they can trade those tokens in for something reinforcing (e.g., a piece of candy).
Use these sticker charts to award your children with stickers when they exhibit good behavior. Once they've reached their sticker quota for the day, reward them with something they don't normally get access to!
