Classroom Traffic Light
A big, glowing red, yellow and green light for the classroom board. Use it for voice levels (silent, whisper, talking is OK), work time (stop, finish up, keep working), or a quick “how’s it going?” check.
Tap a light or press 1, 2 or 3 on the keyboard to switch, and write your own labels for anything else.
