What This Standard Means

What Students Need to Do

Students read short excerpts from the Constitution, the Louisiana Purchase treaty, the Fourteenth Amendment, a civil rights law, and a trade agreement. They put the documents in order and explain what changed in the federal government's powers or duties.

What Mastery Looks Like

A student can explain that the Louisiana Purchase added land for Congress to govern, not a new constitutional power. They can show how the Fourteenth Amendment and the 1964 Civil Rights Act addressed different kinds of discrimination, using a detail from each.

Common Misconceptions

Students may think the Louisiana Purchase gave Congress its first power to govern territory. They may also assume a trade agreement cancels U.S. laws, or that the Fourteenth Amendment directly banned discrimination by every private business.

How to Assess It

Give students the Constitution's territory clause and a short excerpt from the Louisiana Purchase treaty. Ask: “Did the treaty give Congress a new power or more land to govern? Use one detail from each source.”

Ways to Teach It

  1. Give pairs printed excerpts from the Constitution's territory clause, Louisiana Purchase treaty, Fourteenth Amendment, and Civil Rights Act; build a dated power-and-duty timeline.

  2. Ask: “Did the Louisiana Purchase create a new congressional power or give Congress more land to govern? Use two source details.”

  3. Play a card match: pair the Fourteenth Amendment with state equal protection duties, and the Civil Rights Act with bans on discrimination in public accommodations.

  4. Show a U.S. Customs import form and a USMCA tariff excerpt; ask who sets and enforces the rules for goods crossing the border.
