What This Standard Means

What Students Need to Do

Students explain how the Court used equal protection and due process in cases about segregation, marriage, speech, and abortion. They trace changes across the rulings. They use opinion excerpts to judge the Court’s reasoning.

What Mastery Looks Like

Students can explain why Brown rejected Plessy’s separate-but-equal rule for public schools. They can explain why Gitlow applied speech protections to states but upheld the conviction, and compare the marriage rulings in Loving and Obergefell. They can explain Roe’s due process reasoning and why Dobbs overturned it.

Common Misconceptions

Some students think due process only covers courtroom procedures, so they miss its role in speech and abortion rulings. Others assume Gitlow won because speech protections applied to states. Some think Dobbs banned abortion nationwide, rather than ending Roe’s federal constitutional protection.

How to Assess It

Give students brief excerpts from Plessy and Brown. Ask: “Why did Brown reject separate but equal in public schools? Use one phrase from each excerpt to compare the Court’s reasoning.”

Ways to Teach It

  1. Give pairs seven case cards with a holding and short opinion excerpt; have them arrange the cards by year and label each constitutional claim.

  2. Ask: “What changed between Plessy and Brown?” Have students cite one sentence from each ruling in a written answer.

  3. Play a case-match relay: teams pair seven case names with holdings, then defend one match using a clause from an excerpt.

  4. Print a county marriage license application and an Obergefell excerpt; ask students why the county cannot refuse a same-sex couple.
