I love positive reinforcement!!! My students keep a sticker chart in their school boxes. At the end of each day, if they have kept all of their cards, they get a sticker on their chart. After they earn 10 stickers they earn a prize. I have a little prize box full of October trinkets. Pencils, stickers, erasers, bubbles, dollar store treasures!!! Here is the October card we are using next. Click here for sticker chart.
