FREEBIE! I’ve found that the most effective way to keep things calm (yet still fun!) in my classroom is to constantly mix up my reward system! My expectations always stay the same, but how I reward positive behavior is constantly changing. In order to keep things fresh and fun, we started using this motivating Bravo Behavior Board I made up in our classroom.
Each time a student BLURTS out loud without raising hand they have to take one down. Last person to have all 3 gets rewarded!--I've seen this implemented in a first grade classroom with a lot of success!
