Think of a couple of objects
Put students into groups and give each group a object word. (example: picture frame)
The groups must then think of as many uses as they can for the object. (example: Use it like a horseshoe and try to throw it on a peg as a game, Use it as a necklace, etc.)
Alternatively, you can give all the groups the same object word and have students race to see who can come up with the most uses for it.
