My practicum teacher has something similar to this and I think its amazing!!! She lets them change their clip throughout the day based on behavior. She doesnt just make them stay on red. She gives her students a chance to improve.. I hope to be justttttt like her one day! She is my teacher hero!
It gives students the opportunity to move up the chart with good behavior instead of merely punishing the negative. I use this in my room except I have mine on a yard stick to make it portable. Really good classroom management tool :)
