Insanely EASY Classroom management strategy. I teach 3 Block classes, and each class is assigned a color, at the beginning of the year. So, I use their color to make the chain. I reward the class randomly, but regularly. They don’t know what they may get a chain for on a given day, but I give at least two opportunities. I do this over a two week period and the class with the longest chain gets a reward, like outside lunch. It definitely is motivating and it works!!
