The Standard

Demonstrate command of the conventions of standard English capitalization, punctuation, and spelling when writing.

Common Core State Standards for English Language Arts · Language Standards

What This Standard Means

Students need to edit their own writing for correct capitalization, punctuation, and spelling, especially in polished academic and professional work. They should make choices that fit formal English, not just rely on spellcheck or a teacher to catch errors.

Mastery looks like clean final drafts with punctuation that guides meaning, titles and proper nouns capitalized correctly, and spelling checked in context. Students often miss comma patterns, apostrophes, semicolons, capitalization in titles, and homophones like affect and effect.

Ways to Teach It

  • Give students a printed paragraph with 15 errors in capitalization, punctuation, and spelling, then have them correct it in pairs with colored pens.
  • Ask students to explain how one punctuation change can alter the meaning of a sentence from their current essay.
  • Use a two-minute edit ticket where students fix five sentences and label the rule used for each correction.
  • Have students compare a polished job application email with an error-filled version and identify which one builds credibility.
