Developed for use in middle and high school classrooms, Mission US engages students in the study of transformational moments in American history. Each mission consists of an interactive game and a set of curriculum materials that are aligned to national standards and feature document-based activities. The game immerses players in rich, historical settings and then empowers them to make choices that illuminate how ordinary people experienced the past. The Educator's Guide provides a wealth of resources and activities for both teachers and students, including primary source documents that show the broader social, political, and economic context of events and perspectives featured in the game. Since some of the topics Mission US explores are difficult, it is recommended that teachers/parents preview the game content to make sure it is appropriate for their students/children.
