Teach a Lesson

11/20/2025

Students deepen understanding of a math concept by teaching it aloud to an AI peer.

Learning Goals

Students will:

  • Deepen Conceptual Understanding: Explain and justify a mathematical idea in their own words.
  • Strengthen Metacognition: Notice where understanding is solid and where it needs refinement.
  • Practice Mathematical Communication: Articulate definitions, reasoning, and applications clearly.
  • Guarded AI Collaboration: Engage an AI that listens, asks clarifying questions, and presses for deeper explanation.\

Materials

Task

Students engage in a voice-to-voice conversation with AI, explaining and clarifying a math topic. If solving problems:

  • Show work on scratch paper
  • Speak steps aloud while solving

Deliverables

  • Any scratch paper used
  • A shared chat link of their conversation

Lesson Structure

[10 mins] Introduce the Purpose

Frame the activity around active recall.

Explain: When you explain an idea out loud, you quickly notice which parts make sense—and which do not. Teaching forces organization, precision, and reasoning.

Tell students they will use AI as a role-play partner. The AI acts as a peer who wants to learn about [math_topic] from them.

Demonstrate how to:

  • Use voice mode in ChatGPT
  • Share the conversation link when finished

[30 mins] Prepare + Teach

Step 1 — Human-First Thinking (No AI Yet)

Students first review the math concept independently. They prepare a short lesson for their “eager peer” GPT.

They begin teaching by explaining:

  • Key definitions
  • Important formulas
  • Why those formulas work
  • How to apply them

If walking through an example:

  • Solve on scratch paper
  • Speak each step aloud
  • Justify why each step is valid

Students complete the assignment when their AI peer demonstrates solid understanding and says:

“Thank you for teaching me about [math_topic].”
