I'd like to do a treasure hunt at DS's party. There will be about 25 children in a small hall with garden. I don't want it to be frenzied free-for-all so I was thinking ofeither splitting them into small teams and getting each team to find a specific number of object (e.g coloured stars) to bring back and exchange for a prize, or to do proper clues and keep them in one big group and share out the "treasure".
I'd be interested to hear you treasure hunt experiences.
