If you are curious about what I'm tempting my middle schoolers with, you too can check out my suggestions on their blog. It covers everything from Elephant and Piggie books to books that acknowledge teen sex.
My reading classroom changes from day to day, man. One day I can't get anyone to settle down and read, and the next day they don't want to stop. One kid who hasn't read all year suddenly falls into a book, and another kid who's been happily reading suddenly stalls out. It's delicate and fascinating and frustrating to try to create the just right circumstances and help kids find the just right book. It's also kind of awesome.
