I always know they need to use the bathroom when they raise 1 finger, which helps cut back on accidents! They know they have to raise 2 fingers to get out of their seat, so they don’t roam around my room. If they need help, they raise 3 fingers, so I know to come over. When they have a question they raise 4 fingers. It is really helpful knowing what students need, and it keeps them from shouting out. I would recommend all teachers use hand signals in their classroom!
How do you manage student needs in your classroom?
