Subject: Economics
Lesson Topic: Reasons for the growth of firms
Learning Objective/s:
  • Describe the main motives for firm growth such as economies of scale, market power, profit maximisation, risk reduction, and access to finance.
  • Compare internal (organic) and external (inorganic) growth strategies, outlining their typical methods, speed, control, cost and risk.
  • Evaluate the advantages and disadvantages of different growth strategies using criteria like market size, cost‑benefit, control and regulatory constraints.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Handout summarising growth motives and internal vs external growth table
  • Calculator worksheets for cost‑benefit calculations
  • Printed case study of a firm’s growth decision
  • Sticky notes for group brainstorming
 Introduction:
Begin with a quick poll: “What would you do if your small business suddenly could double its output?” Connect responses to prior lessons on cost curves, then outline today’s success criteria – students will be able to identify why firms grow and contrast organic and inorganic growth methods.
Lesson Structure:
  1. Do‑now (5’) – Students write one reason for growth on sticky notes and share.
  2. Mini‑lecture (10’) – Present key motives and formulae, using the projector and an AC‑curve diagram.
  3. Interactive comparison (10’) – Pairs complete a Venn diagram comparing internal vs external growth using the handout.
  4. Case‑study analysis (15’) – Groups evaluate a printed case, decide on the optimal growth route and justify using evaluation criteria.
  5. Whole‑class debrief (5’) – Groups present findings; teacher highlights misconceptions.
  6. Exit ticket (5’) – Write one advantage and one disadvantage of the chosen growth strategy.
Conclusion:
Summarise that firms grow to lower costs, increase market power and manage risk, and that the choice between organic and inorganic routes depends on speed, control and cost considerations. Collect exit tickets as a retrieval check and assign homework: research a real‑world company’s recent merger or expansion and prepare a brief report.
