Inquiry-Based Lessons in U.S. History: Decoding the Past (grades 5-8) provides primary source lessons that focus on teaching U.S. history through inquiry to middle school students. Students will be faced with a question to answer or problem to solve and will examine primary sources for evidence to create hypothetical solutions. The chapters focus on key chronological periods (e.g., the Age of Exploration to the Civil Rights era) and follow the scope and sequence of major social studies textbooks, with activities linked to the U.S. History Content Standards and the Common Core State Standards for Literacy in History/Social Studies. The three lesson plans in each chapter begin with an essential question that sets the focus for the primary sources and teaching strategies that follow. The lesson plans include differing types of primary sources such as photographs, speeches, political cartoons, historic maps, paintings, letters, and diary entries.
