In each classroom there's a jar to which marbles are added for good behavior. If a teacher other than their own catches them on their good behavior and compliments them, they get to add two marbles. If the principal spots them, it's three marbles. Once a jar is filled, there is a whole-class celebration. The program gets rave reviews.
Professional jealousy is kept at bay.
At some schools, professional jealousy has soured relationships among colleagues, replacing cooperation with competition. There's no possessiveness of materials. The team means you, too. Also, once a month, the cafeteria staff teaches nutrition to student representatives from each class. The reps taste-test new products, too, and review current menu selections.
