Common Core State Standards for English Language Arts

What This Standard Means

Students need to know that language changes with the situation. They should be able to choose formal English for presentations, letters, and speaking to unfamiliar adults, and use a more relaxed style during peer talk or casual group work.

Mastery looks like explaining why one version fits a setting better than another, then revising words and tone to match. Students often get stuck thinking formal means “fancy” or that informal means “wrong.” They need practice matching audience, purpose, and setting.

Ways to Teach It

  • Sort sentence cards into formal and informal piles, then have students rewrite two cards for the opposite setting.
  • Ask students to write two responses to the same question, one for the principal and one for a best friend.
  • Give four short scenarios and ask students to label each formal or informal, with one reason.
  • Compare a text message to a thank-you note, then list the language choices that make each fit its purpose.
