This is an excellent tool for classroom management. Set up a poster with an envelope for each child. Have your students cut out and color the cards- one circle green, one yellow and one red. Every week, each student begins on the girl card. If they don't follow a class rule they are moved back a card, to green, then yellow, then red with an appropriate consequence for each one. Modify and adapt to your specific use. This is a great visual reminder to your students to remember exactly where they stand.
