My students LOVE ClassDojo! I give WEEKLY coupons based on points earned over a week and a daily motivator of a Tushy-Cushy for the two top points earners. Every week is a fresh start and every day new students get to sit of Tushy-Cushies.
Some of my prize box items are theirs to keep, other items are on loan for the day, such as: fidget spinner, fidget cube, stuffed animals, marker set, special recess equipment, etc. There are a lot of ways to make the prizes cost-effective.
