I just found a blog that maybe you already know about (I'm kind of new to this blogging thing), with a post of the same title. The blog is called "Teach it With Class" and Randi has posted some great stuff. (See her post at http://teachitwithclass.blogspot.com/2011/07/your-next-read.html) She found the website, http://www.yournextread.com.
I've seen it about a year ago, but I didn't realize it would create a "web" of books that are related to your last book. Somehow I missed that! I love it! As the mother of one somewhat picky little boy, I love the idea that we can find other books he would like a little more easily.
Can you think of other ways to use this in the classroom? Leave a comment!
