The Standard

Use coordinating and subordinating conjunctions.

Common Core State Standards for English Language Arts

What This Standard Means

Students need to join words, phrases, and clauses with the right linking words. They should use words like and, but, or, so, because, although, when, and if to show how ideas connect. They also need to notice how the conjunction changes the meaning of the sentence.

Mastery looks like students combining short choppy sentences into clear longer ones, and choosing conjunctions that match the relationship between ideas. Common trouble spots are overusing and, starting every complex sentence the same way, or using a conjunction that makes the sentence illogical.

Ways to Teach It

  • Give pairs sentence strips and conjunction cards, then have them combine two simple sentences in three different ways and compare the meanings.
  • Ask students to write about a time plans changed, using because, but, when, and so at least once.
  • Show five combined sentences, have students circle the conjunction and label what it shows, choice, contrast, cause, or time.
  • Use a lunch menu or weather forecast and have students make sentences like, If it rains, we will eat inside.
