I have taught 4th for 15 years. I have seen the clip chart work for others, however, often the students felt shamed and it alienated both students and families. I give a lot of choice in the classroom and natural consequences; if you are being respectful , kind, and working without disrupting then you get to have choice. This could mean choice of center rotation, flexible seating option, partner to work with, or simply which task to complete first. Giving the older students some choice really empowers them and gives them some buy-in in the classroom. Another option is Class Dojo. It’s an online behavior reward system that you can run from your smartphone or computer. The kids love it and it can even be set up so other teachers, like art or music can award Dojo points. It will also keep track of your “behavior reports” and email home status updates. Could be useful to check out.
