Yesterday at our English Club gathering, we played a game where someone wrote 16 random letters in a square on the blackboard. The club members were devided up into 4-person groups. Each group brainstormed words that could be made out of the 16 letters, and then we went around to each group in turn to get another word. If a group was stumped, they were out of the game. This took quite a long time, and turned out 86 words, ranging in length from a to homepage. It was a great activity. I was really surprised at how many words people could come up with.
