Math Folder

All of my students have this taped to the front (p.1), back (p.2) and insides (p.3 cut in two parts and put on the front of each pocket) of their math folders.  It provides an easy access resource that is always with the student during class or at home for homework.  We refer to these constantly during class.  I have larger posters of most of these that I hang around the room, too.  I use clear packing tape over the whole page--that way it also turns into a wipe-off surface that can be used with dry erase markers.
