If a student received all green and blue for the month, there were able to choose between a small prize or free snack from the lunch room.
If a student received all green they were able to pick between a homework pass or 2 points on their spelling quiz.
If a student received all yellow for the month parents were alerted and a before recess they had to write at least 2 sentences on how to better their behavior
If a student was to get all red, parents are alerted as well as recess being taken away.
I find that this example is helpful, especially for younger students because it pushes them to do and be better in the class. No kid wants to be all red, every child wants to be able to go outside and play with their friends. This chart is a boost to help kids maintain their behavior not just in the class but as well as in their own home.
