ELAGrades 9–10Key Ideas and Details

The Standard

Cite strong and thorough textual evidence to support analysis of what the text says explicitly as well as inferences drawn from the text.

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

What This Standard Means

Students need to make a claim about an informational text, then back it with evidence that is both strong and complete. They should explain what the text says directly and also make reasonable inferences based on clues in the wording, structure, and details.

Mastery looks like choosing the best lines, not just any related quote, and explaining how each piece proves the point. Students often get stuck using evidence that is too general, dropping quotes without explanation, or making inferences that go beyond what the text can support.

Ways to Teach It

  • Give pairs three evidence strips from an article and have them rank strongest to weakest for a teacher-provided claim.
  • Ask students to write: What does the author state directly, and what can we infer from that detail?
  • Use an exit ticket with one claim and ask for one quote plus two sentences explaining how it supports the claim.
  • Have students analyze a product review, citing exact lines that support whether the reviewer is fair or biased.
