Why do you use OneNote to teach?
I like having a write on board option that saves what I have written automatically.
Each lesson is stored within the same notebook and I can easily remind students of previous examples/lesson activities.
The students have read only access to all the board work/worksheets/website links that have been used in a lesson.
I've already created a link to a page in the OneNote, can I change the title/name of that page?
Yes, Links to the page are not dependent on the Page name.
I often add the date to the Page Name during a lesson.
(Alt+Shift+D is the keyboard shortcut to add the current date)
