This document describes an exercise called "The Treasure, the Pirate and the Key" meant to promote discussion and consensus building. Participants are told a treasure has been locked in a chest and they each receive a paper key with different sized teeth. Their task is to design a key that will unlock the treasure by agreeing on the 7 most important things. Two examples of treasures are given: future generations understanding the Red Cross and human contentment. Clues around the room provide possible answers. Small groups then try to reach consensus on ordering the 7 things. Discussion follows on the process and outcomes, with the goal of learning about differences and communication.
