The Standard

Provide reasons that support the opinion.

Common Core State Standards for English Language Arts

What This Standard Means

Students need to back up an opinion with clear reasons. They should not stop at “I like it” or “It is best.” They need to say why, using reasons that make sense and match the opinion.

Mastery looks like an opinion followed by two or more connected reasons. Strong reasons are specific and believable. Students often get stuck giving examples that do not support the opinion, repeating the same reason, or using feelings instead of evidence.

Ways to Teach It

  • Hands-on: Give students opinion cards and reason strips, then have them sort which reasons actually support each opinion.
  • Prompt: Write your opinion about the best recess game, then list three different reasons that would convince a classmate.
  • Quick assessment: Show one opinion and four possible reasons, then have students circle the two strongest matches.
  • Real-world connection: Read a short book review online or in print, then identify the opinion and the reasons the reviewer gives.
