This is a great classroom website for guided reading. You can download many different levels of guided reading books with running records and activities to go along with each book.
I have used this site while working the summer ESY program. it is great to build literacy through leveled reading books, worksheets and comprehension activities.
Tumble Book Library is an online collection of animated, talking picture books which teach young children the joys of reading in a format they'll love.
This is one of my favorite websites. During snack time, I put on one of these stories for the students to watch. The book is usually read by a celebrity and the pictures are shown to the students.
