I like to think of OneNote as a binder with tabs.
You can add any type on content to your notebook, text, pictures, audio, video, music, files, and embedded files. There is really no limit to what you can use to plan your lessons with OneNote.
I have gotten lots of question on how to use OneNote for lesson planning, so I put together a simple tutorial to help get you started.
