I give these out in my classroom as a reward for good behaviors. After the students put their name on a Treat Ticket, they place it in the Treat Ticket bucket. Once a week (you could do more often if you like), I pull out tickets like a raffle drawing and those students get to pick something from the prize box. It's also a lesson in probability, the more Treat Tickets they have in the bucket, the more likely their name will be chosen.
I also attached a fun song to sing when it's time to pull the name from the bucket. Enjoy!
