Lesson Structure

Introduction (10 minutes)

• Begin with a brief recap of opportunity cost: Explain it is what you give up when choosing one thing over another.
• Use a relatable example: "If you choose to spend your $10 on a movie ticket, the opportunity cost could be the pizza you didn’t buy."
• Ask students to share quick examples from their own lives to activate prior knowledge.

Guided Reflection Journaling (25 minutes)

• Explain the journaling activity: Students will reflect on a personal decision they made recently and write about:
  1. The choice they made
  2. What they gave up (opportunity cost)
  3. How they felt about that trade-off
  4. What they learned about decision-making
• Provide prompt questions on the board/sheet:
  • What was the decision?
  • What other options did you have?
  • What were the benefits and costs of your choice?
  • Can you think of a different choice you might make next time?
• Encourage honesty and detailed reflection.
• Circulate to assist and ask probing questions.

Sharing and Discussion (10 minutes)

• Invite volunteers to share parts of their reflections.
• Facilitate discussion on how opportunity cost affects everyday life and how being aware can improve decision-making.

Summary and Consolidation (5 minutes)

• Recap key economic terms: opportunity cost, trade-offs, decision-making.
• Highlight the role these concepts play beyond school, like in business and government.
• Set a challenge: Over the next week, students to notice at least one decision with an opportunity cost and jot it down in their journal.

Assessment

• Formative assessment through journal entries, checking for correct understanding and personal connection to opportunity cost.
• Observations during discussion for use of vocabulary and conceptual understanding.

---

Differentiation

• Provide sentence starters or word banks for students who need extra support.
• Challenge extension: Ask advanced students to consider how opportunity cost affects communities, referencing indigenous barter/trade systems briefly (connecting to elaboration AC9HE7K01_E4).
