Subject: Economics
Lesson Topic: effective demand
Learning Objective/s:
  • Define effective demand and differentiate it from mere willingness to buy.
  • Explain how non‑price determinants shift the demand curve.
  • Analyse the impact of a change in effective demand on market equilibrium.
  • Apply the demand function to calculate the effect of income changes on demand.
  • Evaluate policy scenarios using determinants of effective demand.
Materials Needed:
  • Projector or interactive whiteboard
  • Slide deck with demand curves and determinants
  • Handout of demand‑function worksheet
  • Graph paper and calculators
  • Whiteboard markers
  • Example data set for income‑demand calculation
 Introduction:
Begin with a quick poll: “If you had an extra £10, which product would you buy?” to activate prior knowledge of willingness to purchase. Review the concept of quantity demanded and introduce the need to consider purchasing power. Today’s success criteria: students will be able to define effective demand, identify its determinants, and predict equilibrium changes.
Lesson Structure:
  1. Do‑now (5’) – Short quiz on willingness vs. ability to pay; teacher checks responses.
  2. Mini‑lecture (10’) – Define effective demand, show diagram, discuss non‑price determinants.
  3. Interactive activity (12’) – Groups plot demand curves and demonstrate shifts when income changes.
  4. Guided practice (8’) – Solve the example calculation together, highlighting the shift in intercept.
  5. Class discussion (10’) – Relate determinant changes to real‑world policy examples (taxes, subsidies).
  6. Formative check (5’) – Exit ticket: write one determinant and its expected effect on the demand curve.
Conclusion:
Summarise that effective demand combines willingness and ability, and only non‑price factors shift the curve, altering equilibrium price and quantity. For the exit ticket, students note the determinant they found most impactful. Assign homework: complete the worksheet on income‑demand shifts.
