My 10 year-old DS's descriptive writing is developing beautifully, but he hasn't yet grasped how to structure his stories effectively. They tend to be very long, and a little random.
As he normally reads chapter-books, which don't serve as good examples for the stories he writes in class, I was thinking it might help if I bought him some books of short stories instead. Any recommendations? He likes fantasy books best (e.g. Lord of the Rings, Harry Potter, Artemis Fowl, Fighting Fantasy).
