Evernote certainly isn’t unknown, but it deserves a shout-out for the ways it can help teachers with the staggering amount of paperwork they accumulate over the course of a school year. Evernote is designed for saving everything, like email attachments and pictures of handwritten notes, and would work well as a hub for lesson plans.
Don’t overlook two other key Evernote apps:
Penultimate as a digital notebook and
Skitch for marking up images, maps, and web page clips.
If you find yourself using Evernote constantly it may be worth the premium subscription, which gets you additional storage and some nice search features for $45 per year.
