Epic! lets educators create a free virtual classroom with up to thirty students. They can then access any of the 15,000 eBooks that are available on the app (via PC, laptop, tablet or phone) and teachers can monitor what is being read and by whom.
Families have to pay if they want access to the site at home, though it’s unclear to me how Epic! can tell where students are when they are reading. Perhaps it’s based on the time of day it’s being used?
Regardless, it’s another good resource that students and teachers can use for either independent or classwide reading.
