Use these 13 pages in a binder with sleeve protectors to give your students access to reference materials. I keep one in each desk in a binder or a folder with prongs. It is amazing how many of my students pull it out on a daily basis. The sleeve protectors also allow them to use a dry erase marker on any page.

I also add pictures of anchor charts to these reference binders as needed.
