Well, I was reading the other post and I started thinking about whether or not you let your students have water bottles and/or snacks in class. I have been teaching for five years now. I have always let my students have a water bottle (no larger than 20 oz and it must have a lid to deal with the spilling issues) and a snack (healthy, not too messy & actually snack sized). I used to have an actual snack time, but I got so tired of kids asking if it was time yet, that I started letting them eat snack any time I was not giving actual instruction. My kids know I have final veto over the snack. I can only think of a handful of times in the past that either has been a problem. So, what do you do?
