Before we discuss classroom rules I tell the kids we are going to play a game. Each group has a travel size tube of toothpaste. First I tell them to squeeze all the toothpaste onto a paper plate. Then I tell them the game is to try to get all of the toothpaste back into the tube without using any tools expect a toothpick (including not using their hands!). Well, it doesn't work. I then tell them that the toothpaste is like words we speak. Once we say an unkind word we can't put it back in our mouth. Then we talk about repecting one another and our classroom rules. I heard about this idea from Dr. Dobson.
