The NaNoWriMo homeschooling group is going well. We get together, eat snacks, I give a short talk, giving ideas they can take or leave, make plot bunnies, write, and laugh a lot!
My suggestion this week was this to write what your primary theme is, then interview your main character regarding it. How does he/she feel about it? Just free write in first person as if you were typing out his/her exact words. This gets you to connect with your character and your main theme.
Plot bunnies! Some of us made these at a NaNo café gathering a while back. Each person writes some little detail or plot device that might help somebody with writer's block get unstuck. And you fold it into an origami rabbit. Toss them all in a basket and each person takes one. They aren't to open it unless they're really stuck. Here's a link to simple origami rabbit instructions.
If you don't have a NaNo group, you use the random writers' block plot cures post I wrote last year. I've actually used it myself a couple of times. Quite useful.
