Les adjectifs

We've been studying adjectives in my Grade 9 Academic French class. I found this great activity over at the Farnsworth Family Blog, that they use at church as part of their youth activities and thought it would be perfect to practice using adjectives to describe each other.
I put my students in friend groups so that they would actually be able to describe each other. Together they had to brainstorm a minimum of five adjectives to describe each person. The person being described was not supposed to contribute any suggestions, they were only allowed to object if they didn't agree with what was chosen for them.
And the rest is self-explanatory. It involved a chair, markers, a whiteboard behind them and all the words written around their head. Oh yes, and the best part was the berets that I made them wear. There were a few, ok, make that a lot of groans and mumblings of "Oh gross, we have to wear that?!", but it was like the cherry on top! We took pictures with our phones and they were all emailed to me. My idea is to put them up in class.
I think the activity could use some tweaking, such as, adding more adjectives, five adjectives seems to be too little. Perhaps next time I'd throw in a couple of sentences? What do you think?
