History is what happened. But, what is recorded as history is not always what happened. Changing Frontiers attempts to look at United States History honestly and fairly. In this full-color text, students learn about pre-Columbus Americans, European discoverers, explorers, and colonists. They follow American history through the formation, growth, and struggle of the nation. Sidebars and extra info nuggets, along with “perspective boxes,” sharpen students’ understanding of history. Study and discussion questions conclude each section.
