Build It Game
blocks, scraps of wood, twine, sticks, ... any materials with which to build.
Make a pile of materials for each team.
Each team has 2 minutes to inspect their materials, without touching anything. They also need to decide what they are going to build.
Then, each team has 3 minutes to build their structure, without talking.
Be sure to explain all the rules before they start so they can make a plan on how they will accomplish their goal.
After the game, discuss how teams communicated without talking. Did someone just take over or did everyone co-operate? What would they do differently if they tried again?
