Discussion

Puberty Vocabulary Match

Purpose: Deepen understanding of key puberty terms and practice respectful, accurate language in small‐group discussion.

Materials:

Setup:

  • Arrange students into groups of 3–4.
  • Give each group a shuffled deck of vocabulary cards.
  • Assign one student per group as the recorder (writes on chart paper) and one as the presenter.

Discussion Steps

1. Sort & Categorize (5 minutes)

  • Task: Sort each card into one of three piles: “Changes for Girls,” “Changes for Boys,” or “Both.”
  • Guidelines:
    • Read the term aloud before sorting.
    • If you’re unsure, hold the card and discuss with your group.

Follow-Up Question: How did you decide whether a change applies to girls, boys, or both?







2. Define & Clarify (5 minutes)

  • Task: For each pile, pick two cards and write a student‐friendly definition on chart paper.
  • Roles:
    Reader: Reads the official definition from the card.
    Explainer: Puts the definition into your own words.
    Recorder: Writes the group’s version clearly.

Follow-Up Question: Which term was hardest to define and why? How did you help each other understand it?







3. Use in Context (5 minutes)

  • Task: Each group creates one example sentence for two different terms. Sentences should show how the body change might feel or look, using respectful language.
  • Example: “When my voice starts to deepen, I might sound different on the phone.”

Follow-Up Question: Why is it important to speak respectfully about these changes?







4. Share & Reflect (5 minutes)

  • Presenters share one definition and one example sentence with the whole class.
  • Classmates give a thumbs-up if the definition was clear or a thumbs-down if it needs more clarity.

Reflection Prompts:

  • What new word did you learn today?
  • How can you use these words to support a friend who is going through puberty?













ASD-Friendly Tips:

  • Provide a visual timer for each step.
  • Offer sentence starters on a handout if needed (e.g., “My body is changing because…”).
  • Check in quietly with any student who seems overwhelmed.

End of Discussion: Gather cards for the next activity or review.
