One of my favorite "book" bloggers discusses a class project she does around the Wizard of Oz. She uses the original Baum version of the story as well as the classic movie we all grew up with. She compares the Oz story with her personal favorite Alice in Wonderland.
She and her students discuss both of these books, their related projects, AND bunches of other "stuff" on her classroom blog AND the students' own blog, blog, blog,...more blogs.
She also has a nice list of other class blogs...3rd-6th grades.
