This page can be used for almost any math concept and age level, although upper elementary and up would get the most out of it. I use it in my 5th grade class to have a team take a concept and become the "teachers" for the day. They need to be experts and hold a review with the rest of the class on their topic. There is a list of questions for them to consider, some of which are as basic as, "Who is going to present the introduction?", and "What materials and/or manipulatives will you be using with this review?".
