This book presents simulation activities for significant events in U.S. history from 1787-1868. Intended for student involvement, the simulations require student research and practice in order to carry out the designated roles. The simulation and role play serve to involve the students actively in their learning, using both the affective and cognitive domains. The simulations presented focus on the: (1) Constitution Convention; (2) Missouri Compromise; (3) Treaty of Gudadalupe Hidalgo; (4) Compromise of 1850; (5) Kansas-Nebraska Act; (6) Southern Secession from the Union; and (7) Impeachment and Trial of Andrew Johnson. Each event featured provides an introduction, offers objectives, describes the teaching strategy, introduces the simulation, and presents the student materials. (EH)
