Using a long piece of printer paper or a longer piece of construction paper is best for this foldable. I normally have to show them once how to fold it. It is helpful to have a ruler and possibly compasses for those students that like clean straight lines and nicely constructed circles. For the foldable, I like to break it up over two days since it is a considerable amount of writing. In the past I have allowed students to look through their notes or textbook to find pictures to draw for the center illustrating the properties. Students usually prefer just to copy instead of finding examples for themselves.
