What This Standard Means

What Students Need to Do

Students identify what an informational text directly states and make reasonable inferences from it. They choose strong, relevant details and explain how each one supports their analysis.

What Mastery Looks Like

Students can answer a question with an accurate claim, then cite several precise details from the text. They clearly explain how the evidence supports both direct analysis and reasonable inferences.

Common Misconceptions

Students often choose the longest quotation instead of the most relevant evidence. They may treat an inference as a guess or include evidence without explaining how it supports their analysis.

How to Assess It

Give students a short editorial and ask: “What can you infer about the writer’s purpose? Cite two details and explain how each supports your inference.”

Ways to Teach It

  1. Cut an article into paragraph strips, then have pairs arrange two strong evidence strips beneath a claim and justify their choices.

  2. Ask students to write: “Which two details best reveal the author’s viewpoint, and what does each detail show?”

  3. Play Evidence Match by having teams pair claim cards with quotation cards, earning points only when they explain the connection accurately.

  4. Compare claims from a product advertisement with facts from a consumer review, then identify which evidence supports or challenges each claim.
