This is a fun simulation that I have used for both middle and high school students. If you are teaching the economic system of feudalism or the Middle Ages, this is a fun and engaging way to start your unit. It can take as little as 10-15 minutes, but with discussion I would plan for about 30-45 minutes. Tags...
