Lesson Topic: effects of shifts in demand and supply curves on equilibrium price and quantity
Learning Objective/s:
  • Describe how an individual shift in demand or supply changes equilibrium price (P*) and quantity (Q*).
  • Explain how the relative magnitude of simultaneous demand and supply shifts determines the direction of the price change.
  • Apply the determinants of demand and supply to predict curve shifts and analyse the resulting equilibrium outcomes.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Printed worksheets with shift tables and scenario prompts
  • Graph paper and rulers
  • Computers/tablets with an online supply‑demand simulation
  • Exit‑ticket slips
 Introduction:
Begin with a quick poll: “What real‑world event could make consumers want more of a product?” Connect responses to prior knowledge of demand and supply curves. State that by the end of the lesson students will be able to predict how any shift alters equilibrium price and quantity and justify their reasoning.
Lesson Structure:
  1. Do‑now (5') – Mini‑quiz on determinants of demand and supply; students write answers on sticky notes.
  2. Mini‑lecture (10') – Review shift vs. movement, illustrate single‑curve shifts with projected graphs.
  3. Guided practice (15') – In pairs, use the “Effects of Individual Shifts” table to predict direction of P* and Q* for given scenarios.
  4. Interactive simulation (10') – Students manipulate demand and supply curves in an online tool and observe new equilibria.
  5. Combined‑shifts activity (10') – Analyse a case where both curves shift; decide which shift dominates and sketch the resulting equilibrium.
  6. Check for understanding (5') – Exit ticket: write one sentence describing the effect of a specified shift on P* and Q*.
Conclusion:
Recap the three key take‑aways: shifts move the whole curve, the larger shift dictates price direction, and quantity follows the overall direction of movement. Collect exit tickets and remind students to complete the homework worksheet, which contains three new shift scenarios to analyse independently.
