In the Zip File there is also a Color Coded Stop Light Sign. The sign has a Green Keep Working Circle, Yellow Yield Triangle, and Red Stop Sign. You can give students or groups color coded sticks, chips, cards, clips or charts. have them keep the color coded items stacked or in a container on the corner of their desk/table. If student/group is working ok, the green item should be visible. If needs teacher check or assistance and can keep working, the yellow item is visible. If stuck, stopped working and needs immediate teacher help, the red item is visible.
Quick Visual for teacher and other students, so everyone understands red is high priority and only to be used if can not continue.
