Wouldn't you love to have an easy way to track your students progress? Instead of carrying around sticky notes, or a notebook, you can have your ipad handy and be able to jot down a few notes using a stylus or the apple pencil. I use the goodnotes app and use an apple pencil.
I have tried to use Adobe Acrobat app and it has the same results, just a different layout.
