Activities:
Activities can contain up to 20 pages
Activities can be scheduled when they are assigned to students
Activities can be shared to the School/District Activity Library
Unlimited number of Activities can be saved to your Library
Skills (Essential Learning Standards) can be uploaded by the district, so each teacher is not creating their own
