This simulation allows students to experience what it was like to live in the medieval world. For three or four weeks, the classroom becomes a manor, a castle, a monastery, a town, or an army en route to Jerusalem to recapture the Holy Land from the Muslim hordes. The phases of the unit include: (1) feudalism; (2) manorialism; (3) knighthood; (4) monastery; (5) crusades; (6) guilds; and (7) tapestry. Each stage of play involves completion of tasks related to the topic. The culminating activity has students creating a "broad canvas" of their studies. Suggestions are included for modifying the unit for shorter periods of time. (EH)
