I created a printable, on 8.5 x 11 paper, table of contents for Interactive Student Notebooks, marble Notebooks. Students would cut off the extra paper. It fits beautifully into marble notebooks.
One is 200 page/100 sheet notebook
One is 140 page/70 sheet notebook
I am providing .docx for both and .pdf for both
I have my kids number the pages, but I don't make them number the table of contents.
