Have you ever seen and read the awesome website put out by the Office of Letters and Light?
They are the folks who dreamed up and put on NaNoWriMo (National Novel Writing Month). www.http://www.nanowrimo.org/.
Each November, they challenge and support adult writers, with lots of humor and panache, in completing a novel in a month.
Their Young Writers Program aids teachers, homeschooling parents and youth librarians in using NaNoWriMo's free curriculum and lesson plans in their classrooms.
