The Standard

Evaluate various explanations for actions or events and determine which explanation best accords with textual evidence, acknowledging where the text leaves matters uncertain.

Common Core State Standards for English Language Arts · Reading Standards for Literacy in History/Social Studies 6—12

What This Standard Means

Students need to compare different explanations for a historical action or event, then judge which one is best supported by the text. They must cite evidence, weigh the strength of competing claims, and notice when the source does not give enough information to be certain.

Mastery looks like a student saying, “This explanation fits best because the author gives these details,” while also naming what is missing or unclear. Students often get stuck treating all explanations as equal, relying on outside opinion, or forcing certainty when the text is limited.

Ways to Teach It

  • Give students three short accounts of the same event and have them sort evidence under competing explanation cards.
  • Ask students to write: Which explanation best fits the source, and what detail makes you doubt full certainty?
  • Use an exit ticket with two explanations and one source excerpt, asking students to choose, cite, and name one uncertainty.
  • Connect to news analysis by comparing two explanations for a current policy decision using only details from one article.
