Instead of using a Table of Contents at the front of your notebooks, use an Index in the back. This separates lessons/ideas/subjects alphabetically for quicker student reference.
File is a MS Excel document, 6 pages long, fully editable. Includes a tab on the first page that folds over to the next page. File is sized to fit nicely into a composition notebook. Use it blank or fill it out with all topics before giving to students to make it a little easier for them.
