I award stickers to my students for good behavior. They have a chance to earn two stickers a day, one for morning behavior and one for afternoon. Once they accumulate ten stickers, they are rewarded with a fireball or lollipop. When they reach twenty, they win a prize from the Prize Box which is filled with Pokemon items, candy, markers, school supplies, etc. My students are excited when they earn enough to win a prize. This system works very well.
