To help save some pages in your Interactive Notebook, use a booklet table of contents. There are 3 pages for the table of contents. I have provided directions and a diagram for how the table of contents booklet should be assembled.
This booklet should have the back page taped to the interactive notebook page since after the booklet is assembled, it can be a little heavy for glue. By taping it, you are ensuring that it will last until the end of the year.
