A Quick Game: The Eight-Door Challenge
Number eight doors, boxes or cups. Spin to choose the one that hides a small prize, and keep the result secret. Players guess, and you say "higher" or "lower". If they halve the range each time, three guesses always find it. It is a nice way to teach kids how a binary search works.
