This would be a very fun activity the first week of school! Teacher says a statement (ex. Switch sides if you like hot dogs more than pizza.) and the students either stay or move. The kids could also talk about why they did/didn't move. Fun!!!
writing prompts or questions on jenga blocks. could do something exciting when they all fall down (but not too exciting to make kids knock it down on purpose! ha ha)... maybe a free write for that day or something
