Help students deconstruct, explain, and summarize primary sources
Did you know that September 17 is Constitution Day and Citizenship Day? A day established as a reminder of the moment in 1787 when the U.S. Constitution was signed. At the heart of that vision is the preamble—a short but powerful statement of the nation’s goals.
Teaching students to analyze and unpack the preamble is more than an exercise in reading history; it’s about connecting with the promises of justice, liberty, and common good that still shape the nation today. And because interpreting the preamble is a common expectation on standardized assessments, it is both a civic and academic priority. More importantly, when students learn to decipher this primary source, they gain the ability to question, reflect, and recognize their own role in carrying forward the ideals of citizenship.
