When I first started teaching, I had the worst class ever. I tried one thing after another until I was able to find something that worked in controlling their behavior. I finally went with a color chart to have a visual reminder in keeping their behavior in check. I have 5 colors (although after Spring Break, I go down to 4 colors to "prepare students for next year"). I flip the students each time they are not following the classroom rules. I also believe in flipping students back the good way if they show improvement in their behavior. This chart has worked well for me for 7 years.
