Raz-Kids Reading Program

Raz-Kids (http://www.raz-kids.com/) is a great site for developing reading skills (fluency, decoding and comprehension) for elementary level students. They have an extensive set of short stories that are leveled (based on grade, DRA, Reading Recovery and Fountas/Pinnell). You can allow students to pick the books they want to read from the library or what I like best is set up individual libraries for each student based on their reading level. Students can read or listen to the stories and there is a short comprehension assessment after each one. You can generate a set of reports that track student progress. New books are added on a regular basis. I use it as part of my Reading Workshop, primarily for my struggling readers, but it can also be used for centers or whenever a student has access to a computer and time to read. This site is associated with another excellent resource, Reading A-Z (http://www.readinga-z.com/theme/index.html).
The only negative is that there is a cost associated with the site. It’s dependent on the number of computers that are licensed. They do have a set of books that can be tried free of charge. I’m curious if anyone knows of a similar site that may be free of charge?
