Lesson Topic: Drawing and interpretation of supply curve diagrams to show different PES
Learning Objective/s:
  • Describe the concept and formula of price elasticity of supply.
  • Identify the main determinants that affect the elasticity of supply.
  • Draw and label supply‑curve diagrams for each type of PES.
  • Interpret how quantity supplied responds to price changes on each curve.
  • Apply PES analysis to real‑world examples and exam‑style questions.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed worksheets with diagram templates
  • Graph paper and coloured pencils
  • Calculator for PES calculations
  • Sample data cards for practice questions
 Introduction:
Begin with a quick poll: “What happens to the amount of a product you’re willing to sell if its price rises?” Connect this to prior learning on price elasticity of demand, then explain that today students will master drawing supply curves that illustrate different elasticity levels and will be able to explain the outcomes.
Lesson Structure:
  1. Do‑now (5'): Students answer the poll on sticky notes; teacher records responses.
  2. Mini‑lecture (10'): Define PES, present the formula, and discuss key determinants with slides.
  3. Guided practice (15'): Teacher models step‑by‑step drawing of the five supply curves on a projected graph.
  4. Pair activity (15'): Learners use worksheets to draw each curve, label axes, reference point, and show a price change; teacher circulates for feedback.
  5. Interpretation quiz (10'): Pairs explain the movement along each curve when price rises.
  6. Exit ticket (5'): Write one real‑world example of a product with elastic supply and one with inelastic supply.
Conclusion:
Recap how the shape of the supply curve reflects producers’ responsiveness to price changes. Students complete the exit ticket summarising key insights, and for homework they will calculate PES for a given data set and sketch the appropriate curve.
