The Rule of Law is an important concept in understanding the Constitution; however, it is difficult for many people to define. Documents from the era of the drafting and ratification of the Constitution have been debated throughout history, as scholars and leaders have grappled over the proper relationship between the government and the governed. Moreover, the Rule of Law was established in the U.S. Constitution and enforced in the judicial system of the United States through judicial review. The first day of this lesson uses historical quotations to help students develop understandings of conceptions of the Rule of Law. In the second day of the lesson, through small group work and class-wide collaboration analyzing Supreme Court cases, students will reflect on how their understandings of Rule of Law relate to the Constitution, the judicial system, and their daily lives.
