    A compound sentence joins two complete thoughts with a coordinating conjunction, and a comma marks the seam: the bell rang, but nobody moved. Fourth graders test each half: if both could stand alone, the comma goes before the joining word.

  2. 5th grade

    Examples and teaching notes

    Fifth graders punctuate compound sentences automatically and use the both-halves test to decide when the comma belongs, which prevents the opposite error of sprinkling commas before every and. The skill anchors the sentence-combining work that makes writing flow.
