The Standard

Produce complete sentences, recognizing and correcting inappropriate fragments and run-ons.

Common Core State Standards for English Language Arts

What This Standard Means

Students need to write complete sentences with a subject and predicate. They also need to spot sentence fragments that are missing a who, what, or full thought. They need to find run-ons where two or more complete thoughts are jammed together without correct punctuation or joining words.

Mastery looks like students fixing their own drafts, not just worksheets. They can explain why a sentence is complete or not. Common trouble spots are sentences that start with because, long sentences with lots of ands, and comma splices like I went home, I ate dinner.

Ways to Teach It

  • Give pairs sentence strips labeled fragment, complete sentence, and run-on, then have them sort and repair each incorrect strip.
  • Use the prompt, Which sounds better and why, Because the dog barked or Because the dog barked, we woke up?
  • Exit ticket: students rewrite one fragment and one run-on from the board as correct complete sentences.
  • Show a messy text message thread, then have students edit three messages so each one is a clear complete sentence.
