I am an elementary school teacher. For this to work for me I need to be able put more information into each class period description.
I am looking for a good digital lesson planning site and iPad app that I can use to get off paper entirely. I would room to describe lesson plans, attach files, and more calendar like features to mark special events (days off, assemblies). I am not sure if you guys plan to go in that direction, if you ever do I would be happy to come give it a try.

have you tried their Schools BETA?
Also look into Teachers.io. Great system for managing teacher things, and it can send homework that you put in lesson plans to students through their student app called myHomework
