Create a bulletin board with 6 different wheels: character, time, weather, setting, feelings, and animals. Included is a sheet with the labels to add to the bottom of the wheel.
Students spin a wheel to get an idea to write about. They can spin as many as they wish to add to the ideas.
I've also put these on portable construction paper sheets that they can take to their desks. You can use a pencil with a paper clip for the spinner.
