I teach fifth grade, and I give out tickets when students exceed expectations, answer a really difficult question, do well on a test, etc. Anyway tickets eventually lead to a school store (about once a month). I teach about 64 kids in 5th grade math. It is getting rather expensive. I do have some coupons- Extra credit points, hw pass, lunch with the teacher, sit next to a friend. Any other suggestions? I am running low on ideas. They are 10/11 years old so it can't be too babyish. At the same time, they are still kids. Help!
