Lesson Plan

• Describe the purpose and key features of a Production Possibility Curve.
• Explain how movements along the PPC illustrate opportunity cost and increasing opportunity cost.
• Analyse the economic interpretation of movements inside the curve and shifts of the PPC.
• Apply the slope concept to calculate opportunity cost using given data points.
• Evaluate real‑world scenarios in terms of resource allocation and efficiency.

• Projector and screen
• Printed PPC diagram handouts
• Worksheet with data tables (A‑B‑C points)
• Whiteboard and markers
• Calculators
• Sticky notes for exit tickets

Begin with a quick poll: “If you could only spend your allowance on one of two items, what would you choose and why?” This connects to the idea of scarcity and trade‑offs. Review the previous lesson’s definition of scarcity and the basic economic problem. State that today’s success criteria are to identify PPC movements, calculate opportunity cost, and interpret what those movements mean for an economy.

1. Do‑now (5 minutes): short quiz on scarcity and basic PPC terminology.
2. Mini‑lecture (10 minutes): recap PPC features, assumptions, and the three types of movement.
3. Guided analysis (12 minutes): examine the movement table; discuss why moving along the curve involves a measurable opportunity cost.
4. Group activity (15 minutes): using the worksheet, calculate the opportunity cost from A→B and B→C and record results.
5. Class discussion (8 minutes): groups share findings; teacher highlights increasing opportunity cost and the shape of the curve.
6. Exit ticket (5 minutes): each student writes one sentence defining opportunity cost on a PPC and places it on a sticky note.

Summarise that movements along the PPC show trade‑offs measured by the slope, and that the curve’s bow reflects rising opportunity costs. Collect exit tickets to gauge understanding. For homework, ask students to find a real‑world example where a country’s PPC has shifted outward (e.g., due to technology) and write a brief explanation.
