ELAGrades 9–10Comprehension and Collaboration

The Standard

Come to discussions prepared, having read and researched material under study; explicitly draw on that preparation by referring to evidence from texts and other research on the topic or issue to stimulate a thoughtful, well-reasoned exchange of ideas.

Common Core State Standards for English Language Arts

What This Standard Means

Students need to show up ready to talk because they have read, annotated, and gathered useful evidence. They should bring specific lines, facts, or examples into the conversation, not just opinions. They also need to use that evidence to build on ideas, ask better questions, and keep the discussion focused.

Mastery looks like a student saying, “On page 4, the author claims...” or “The article’s data supports that because...” and then connecting it to a classmate’s point. Students often get stuck by under-preparing, giving vague comments, or dropping quotes without explaining why they matter.

Ways to Teach It

  • Hands-on: Give students three sticky notes to label claim, evidence, and question before a small-group discussion on tomorrow’s reading.
  • Prompt: Write one discussion comment that uses a quote, then add two sentences explaining how it connects to the topic.
  • Quick assessment: During discussion, tally each student’s text-based comment, question, and response to a classmate on a simple roster.
  • Real-world connection: Have students prepare for a mock school board meeting by bringing two facts from an article about phone policies.
