I purchase Gingerbread Man cookies for my kids and pass one out to each child. I tell them they can't eat it until I say. Once all the children have a cookie, I tell them to take only one bite. Once all of the kids have eaten one bite of their cookie, I show the children the graph. I explain to them that we are going to graph which body parts we all ate. We go around the room and each child tells us the part they ate. I color in a copy of the graph on the Smartboard, while the children color in a box on their own copy of the graph. I then use the graph and ask questions of the children. At the end, we all get to eat the rest of our cookie!
BTW...I white-out the different parts of the Gingerbread Men that the graph indicates were eaten before making student copies.
