1 Finger held up = "I wish to speak"
2 Fingers held up = "I wish to leave my seat"
3 Fingers held up = "I need your help"
Pictures should accompany these directions so everyone is on the same page as to how the fingers should be held up. The teacher should explain the concept, practice the procedure, and then consistently implement the procedure in the classroom. If you have any ideas, please feel free to share!
