I have used Interactive Notebooks in my class for the last 10 years. Each year I put a new spin on them and I am so excited to pass these out tomorrow!!! YAY! This year I purchased the larger composition books (8.5 x 11) from Staples. I also add the duct tape to help the binding stay intact. The covers are printed on card stock and contact paper is put over the covers. Click here if you are interested in having them for your math class!
