A fun project for the kids to do using M&M's. I have done this as an introductory project and have also done it as a wrap up project. It all depends on the students ability and previously learned material. The kids need to bring in two bags of M&M's. One plain and one peanut. I usually make them bring in the snack packs. I have also bought them in bulk and handed them out. Up to you. Fun project.
