What This Standard Means

What Students Need to Do

Students break an argument into its assumptions, claims, and supporting evidence. They check each part against other reliable sources and decide whether those sources strengthen or weaken the argument.

What Mastery Looks Like

Students can separate an author's assumptions, main claims, and supporting details. They compare those parts with credible sources, then explain whether the argument holds up and why.

Common Misconceptions

Students may treat every statement as a claim or assume cited evidence is automatically reliable. They may also call sources contradictory when the sources address different questions or time periods.

How to Assess It

Give students a short historical argument and a second source. Ask them to name one claim and explain in two sentences how the second source supports or weakens it.

Lesson moves

Ways to Teach It

  1. Give pairs a claim, evidence cards, and two source excerpts, then have them sort each card as support, contradiction, or unrelated.

  2. Ask students to write: Which assumption does the author expect readers to accept, and what source could test that assumption?

  3. Run a corroboration relay where teams match claims to source excerpts, then earn points by explaining each match accurately.

  4. Compare two news reports about the same public policy and identify where their evidence agrees, conflicts, or leaves questions unanswered.
