The Standard

Delineate and evaluate the argument and specific claims in a text, assessing whether the reasoning is valid and the evidence is relevant and sufficient; identify false statements and fallacious reasoning.

Common Core State Standards for English Language Arts · Reading Standards for Informational Text

What This Standard Means

Students need to trace an author’s argument from main claim to smaller claims, reasons, and evidence. They should judge whether each reason actually supports the claim and whether the evidence is enough, on topic, and trustworthy.

Mastery looks like an annotated article with claims labeled, evidence checked, and weak reasoning named. Students often confuse a topic with a claim. They may accept statistics without checking source or sample. They also miss common fallacies, like slippery slope, straw man, false choice, or attacks on a person instead of the idea.

Ways to Teach It

  • Give pairs a printed editorial and have them color-code main claim, subclaims, reasons, evidence, and possible fallacies.
  • Ask students to write: Which claim in this article is strongest, and what exact evidence makes it convincing?
  • Use a five-minute exit ticket with one short paragraph, asking students to label the claim and judge one piece of evidence.
  • Show a political ad or product review, then have students list claims, evidence, missing information, and any misleading reasoning.
