Writing for writing's sake is just awful. WHY do we write?
Look through the Writer's Workshop topic on this site and see if it will fill the need you have. You can always add 'something' if you see a void. I hope to show children that there really IS a reason to write and it can be fun!
Yesterday I made 12 posters to be used with my Writer's Workshop. Some of the topics (crafts) were listed in my curriculum, some from this site. There are SO MANY that can be covered in an enjoyable way, leaving the child with a desire to write more books.
