What This Standard Means
What Students Need to Do
- Students choose facts, examples, and quotations that directly back each claim. They explain the link between evidence and claim, check source trustworthiness, and represent the topic accurately.
What Mastery Looks Like
- A strong student selects specific evidence from dependable sources and avoids facts that are merely related. The student explains how each piece proves the point and uses source details accurately.
Common Misconceptions
- Students often insert a quotation without explaining it, or choose evidence that matches the topic but not the claim. They may trust every website or distort a source by removing context.
How to Assess It
- Give students a claim and three short source excerpts. Ask them to choose the strongest excerpt and write three sentences explaining its fit and the source's trustworthiness.

Ways to Teach It
Give pairs printed claim and evidence cards, then have them match, reject weak evidence, and annotate why each accepted card works.
Write: Should schools limit homework? Use one provided article and explain how two details support your position.
Play Evidence Court: teams earn points by defending one source excerpt and challenging another for relevance, accuracy, or trustworthiness.
Compare two online reviews of the same product, then decide which recommendation is better supported and explain why.
