I have a teacher friend who has been having some struggles with student behaviors. You know, calling out, inappropriate language, wandering the room, typical middle school behavior. However, instead of letting the students control the room, she took action and created this ingenious management plan.
Every student has a white piece of paper that has the classroom expectations on it. She said she likes that the students have those reminders right in front of them. If I student breaks one of those expectations she simply, and without a word, moves their paper clip down a notch. "Strike one". She does this until they get to "strike three" and upon that strike the student relocates themselves to the refocus area in the room.
The green card is actually double sided with a green side and a red side. Green side up means the student does not need assistance in the activity. We've noticed that our students just like to yell "Miss" really loudly when they need something and this way the expectation is that they are to flip their card to red to signal help is needed.
Finally, the good kids. Each classes is given a container and at the end of the class period if a student has no strikes they get a piece of macaroni to put into the container. Once the container is filled the students in that class well get a reward. Always remember your all-stars!
