Lesson Plan

• Describe the key determinants that influence the price elasticity of demand.
• Calculate price elasticity of demand using the midpoint (arc) formula.
• Analyse how each determinant alters consumer responsiveness in real‑world examples.
• Evaluate the implications of different elasticity levels for business and government policy.

• Projector and screen for slide presentation
• Whiteboard and markers
• Handout with the determinants table
• Calculator worksheets with PED data
• Laptops or tablets for group research
• Exit‑ticket slips

Begin with a quick poll: “What would you do if cinema ticket prices rose by 25%?” Use the responses to link to the concept of price responsiveness. Review the definition of price elasticity of demand from the previous lesson and state today’s success criteria: identify determinants, calculate PED, and apply findings to policy questions.

1. Do‑now (5’) – Short quiz on elasticity definitions and formula recall.
2. Mini‑lecture (10’) – Present the six determinants of PED with real‑world examples (slides).
3. Guided practice (15’) – Work through the cinema‑ticket example, calculating PED step‑by‑step.
4. Group activity (15’) – Each group selects a product, uses the determinants table to predict its PED, and prepares a brief justification.
5. Class discussion (10’) – Groups share findings; teacher highlights policy implications (taxes, subsidies).
6. Exit ticket (5’) – Students write one determinant that most influences PED for their product and a numeric PED estimate.

Summarise the six key determinants and the steps for calculating PED, emphasizing how they guide business pricing and government decisions. Collect exit tickets as a retrieval check. For homework, ask students to locate a recent news article about a price change, estimate the likely PED using the determinants, and justify their estimate.
