Curriculet allows teachers to assign reading material that contains layers of video, multiple choice questions, and annotations which pop up while students are reading (materials normally contained in worksheets). This allows students to answer questions while they read! Many books are free for teachers to use with materials already embedded. But the really powerful part of this site is that teachers can create their own materials to layer on the books! This is a fantastic site for literacy teachers! WOW! Some novels are free, and some can be rented.
