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 example treasures are provided: future generations understanding the Red Cross and human contentment. Participants first work individually then in small groups to order the 7 items before a whole group discussion. The goal is to explore any difficulties that arose in reaching agreement and how people's views were incorporated.
