I am at my wit's end! This group just cannot stop talking! I also have 4-5 who cannot stay in their seats! In the middle of instruction (during a mini-lesson or just new directions), they pop up out of their seats and come up to ask me/tell me things that are completely unrelated to what I am talking about. I mean constant interruptions during my teaching! I have tried: positive reinforcement (this worked at the very beginning-- but stopped really quickly), we have modeled and practiced, I have moved desks (there isn't any better arrangement), I've tried power teaching techniques (class! yes!-- but I can't get all the little sweeties on board), and today I was a total drill sargeant (hate it!). Please help!! What else can I do??
