Thanks for the info on the book levels - I am def. going to start checking out some levels.

DS's teacher to me today: "He reads so incredibly fast, does he actually comprehend what he reads?"
Me: "well, when I ask him about the books, he seems to, but I am not completely sure, I think it depends on the book, he reads everything from Hardy Boys to adult non-fiction."
Teacher: "I think I need to get more books in the classroom"

Thank heavens for teachers who get it.
