Chris Biffle's words, "Don't scold, rehearse," run through my head everytime I see my perfect little classroom beginning to deteriorate. They are very simple words, but they have helped to reshape my mood throughout the day. The first rehearsal always comes as students enter the classroom. Instead of my quietly reminding particular students to enter quietly, I call out Rule 4 (or whatever rule strikes me at the moment). Then we start running through the rules in some random order. By the time everyone is seated, the rules have been chorally repeated and gestured, and some randomly selected individuals have stated/gestured the rules, the class is silent and attentive. Throughout the day, rehearsing rules or moving on with any of the Big 7 keeps the class moving along. I like it.
