This document features "Treasure Chest Coupons!" Students earn stamps on a stamp card, and when their card is full they trade it for a treasure chest prize. I used to spend at least $20 a month filling up my treasure chest with toys, puzzles, and games from the dollar store. I stopped buying junk and instead put these coupons into a special treasure box, and my students LOVE it! Many of the rewards are cheap or free, and involve the entire class!
