The only thing coming to mind would be to bring in a bag of objects. Ask the students to "pop" up with one word to describe the object (color, size, shape, etc). Set up rules such as; no repeats, stand only once per object, and so on. Then divide them into groups and give them additional objects and have them list ways to describe each object.
Or you can try a telecopic text, if you have a projector or SMARTboard, show this to your students. (tap on the grey boxes)
