OK, I don't really think this is what you had in mind, but this is a game we used to play with the children and still do play occasionally when we're all together and feeling silly and nostalgic.
We used to call it Tree Bush. Print off your work sheets, you can have 2 goes to a sheet. You don't need anything but a pencil and perhaps a book to find an initial letter from.
Pick a letter to begin with and set the timer for 2 minutes, then see who can get the most words. Each word scores 1, but if you have a word no one else has thought of you get 2 points.
I think it will make a nice SB background for childhood photos too.

ps: you have doubtless noticed there is no Bush mentioned in our game. That is because none of us could usually think of any and even when we could, there was too much discussion on where a bush ended and a tree began! So we knocked out the Bush, but that's what we still call it!
