Common Core Writing Prompts and Strategies: A Supplement to Civil Rights Historical Investigations is a resource that further aligns our Civil Rights Historical Investigations units with the Common Core State Standards through an argumentative writing assessment. The three Civil Rights Historical Investigation units require students to do history-to gather evidence from primary documents, use that evidence to make claims about the past, and then apply what they learn to their own lives today. This supplement includes specific writing prompts and teaching strategies that ask students to use this evidence to craft a formal argumentative essay about the civil rights movement. In addition, the resource features effective writing strategies for the social studies classroom.
