This resource is by far one of the most helpful to teach reading in the Cyber School environment. I have used the leveled readers in both whole group lessons, and small group intervention lessons. The site is also full of other lesson plans, games, and activities to use with students. Along with pulling materials to use in my lessons, students go on independently and interact with the readers. They can read them, or listen along, and then they answer comprehension questions. It is a great tool for helping students improve comprehension and allowing teachers to collect and view resulting data. I have not encountered any obstacles with this site or its resources.
