This document contains a picture of my Core-Fringe Communication boards. I used simple materials that anyone can find such as a plain manila file folder and 2 sheet protectors stapled to the folder. In my more durable form, I used a heavy duty file folder, cut it in half, then used my binding machine to connect the two.
If you are using the manila folder and are stapling the page protectors, be sure not to staple the opening closed. You will need to change out Core Vocabulary boards and Fringe Vocabulary Boards to meet each student's needs and to easily change activities.
