Setup for Detail Game
Pick an object from home that's somewhat unusual to draw students' attention and to get them observing and describing creatively. (The best object I ever used was a green plaster mold of someone's very crooked teeth, but I was lucky enough to have a roommate with a large stock of odd objects like this). Pass the object around, and going from person to person, have each say one thing that describes the object. At first you'll get boring things like the object's color and its size, so stress the idea of the five senses: What does it feel like when you touch it? Does it have a smell? Taste? Sound? As you get to the middle of the class, ask someone to place the object in a setting. What's it doing there? Or imagine who the object might belong to, and build a story from there.
In a class of reluctant writers, those green teeth produced a great story about a poor woman who was battered by her nasty husband and decided to burn down the house and run away to a swamp to hide. Let them have fun with it and they'll probably surprise themselves with what they come up with, especially as they often begin to try to top one another with the weirdness of their contribution.
