The social studies program in middle school builds chronological and thematic understanding of both world and United States history, while also developing the Social Studies themes of  geography,  economics,  political systems and culture. Each social studies unit is organized around a historical era and at least one social studies theme. A mix of modern content and the lessons of history provide the background knowledge and historical thinking skills that prepare students for high school instruction and their responsibilities as citizens. In grades 6 and 7 the focus of study is on Ancient World History and cultures from Asia, Africa, Europe and Latin America. In grade 8 students learn about the founding and early development of the United States from the Colonial Era and the Revolution through Reconstruction. At all grade levels, students build an understanding of the modern world by applying concepts of geography, economics, political systems and culture to present-day scenarios.
