I am responsible for decorating one of the bulletin boards on the 3rd floor from December to March. I'm going to make the kids write about their upcoming trip to Grade Nationals and Disneyworld. (obviously, they'll write about it afterwards) The exact assignment is going to be to tell me one awesome story in 2.5-3 pages.
And I'm going to invent a set of symbols to use as grades. Like there will be a symbol of two stick figures holding hands that will mean "awesome characters." Or a pair of glasses means "You should have read over this for editing mistakes before you handed it in." A mouth and an exclamation point means "great dialogue!" A smiley face with laugh coming out of it means "Your story is hilarious!" There will be a key on the bulletin board, and of course a more specific description of what I think in my comments on each paper.
I like the idea of grades that offer feedback but are nonsensical.
"What'd you get on your paper?"
"I got a pair of glasses, a bullseye, and two fish."
