Common Core State Standards for English Language Arts · Language Standards

What This Standard Means

Students need to use standard English grammar and usage in their own writing and speech. They should make choices that fit the task, audience, and purpose, then revise when sentences are unclear or incorrect.

Mastery looks like clean, controlled sentences in essays, discussions, presentations, and short responses. Students can explain why a sentence works, not just guess by ear. Common trouble spots include subject-verb agreement, pronoun clarity, verb tense shifts, fragments, run-ons, and informal speech habits showing up in formal writing.

Ways to Teach It

  • Give students five flawed sentences from a class draft and have pairs cut, move, and revise word strips into correct versions.
  • Ask students to explain which sentence sounds more formal and why, using two versions of the same idea.
  • Use a three-minute exit ticket where students correct one run-on, one pronoun error, and one tense shift.
  • Show a job email or college message and have students mark grammar choices that make the writer sound clear and credible.
