Warm Up and Preparation

  • Start class by gathering your students together and telling them a story about yourself, such as what you did the night before, without using pauses. Do this in an exaggerated way so students recognize that you're rambling on. Alternatively, consider reading a short book in the same way.
  • When you're finished, ask students if they noticed anything about the way you told the story. Ask:
    • Why was the story difficult to follow and listen to?
    • How can I make it easier to understand?
  • Ask students to turn and talk to a partner, repeating the exercise of rambling on, then discuss:
    • What was it like to speak in this way?
    • How did it feel to not pause when talking?
  • Tell students that, when writing, we recognize the pauses with punctuation marks like periods and commas.
