Actively Learn
Subscription accounts are available for teachers of grades 6-12.
Actively Learn is a reading platform for the web where students can highlight, annotate, and discuss text as they read. Teachers can assign texts to students solo and in groups so that whole classes can read, annotate, and interact around texts at their levels. The site contains thousands of free ELA, science, and history texts, from "The Picture of Dorian Gray" to George Washington's Farewell Address to recent news reports on climate change. Don't see what you want? Teachers can upload any text of their choosing, from online articles to their own media. If you or your school spring for a paid subscription plan, you can also access copyrighted materials through the platform, like full books.
