This 111-page pdf provides a full kit for a classroom activity focused on learning U.S. history within a conflict resolution framework. The activity, focused around the war between the United States and Mexico in the 1840s, sets up a negotiation and mediation between two historical figures from the period. The activity comes from Volume One: The Colonial Period through Reconstruction, the first of two volumes available from the NJ Center for Civic and Law-Related Education for teaching conflict resolution and U.S. history. The two volume set was created with supportive funding from the Ford Foundation. More than 25 leading historians helped to provide a rich historical background as the materials were developed and presented. More than 200 teachers from 15 states participated in the institutes and piloted the materials in their classrooms. More information available at
