Lesson Plan
Grade: Date: 17/01/2026
Subject: Economics
Lesson Topic: Revenue
Learning Objective/s:
  • Define total, average, and marginal revenue and state their formulas.
  • Distinguish revenue curves in perfect competition versus monopoly.
  • Apply the short‑run rule MR ≥ MC to decide whether a firm should produce.
  • Calculate profit from given revenue and cost data and interpret the result.
  • Explain how revenue relates to long‑run equilibrium and economic profit.
Materials Needed:
  • Projector or interactive whiteboard
  • Slide deck covering revenue concepts
  • Worksheet with revenue calculations
  • Graph paper and coloured pens for drawing curves
  • Calculator or spreadsheet
  • Sample monopoly diagram handout
 Introduction:
Begin with a quick poll asking how many think a firm’s success is measured solely by sales. Connect this to prior knowledge of cost concepts from earlier lessons and set the success criteria: students will define key revenue terms, sketch relevant curves, and use revenue data to make production decisions.
Lesson Structure:
  1. Do‑now (5') – Short quiz on cost terminology to activate prior learning.
  2. Mini‑lecture (10') – Present definitions and formulas for TR, AR, MR with slides and a simple example.
  3. Interactive graph activity (12') – In pairs, draw revenue curves for perfect competition and monopoly, highlighting where AR and MR coincide or diverge.
  4. Guided calculation (10') – Work through the 100‑unit example, completing a worksheet and checking answers together.
  5. Application discussion (8') – Evaluate a short‑run production decision using the rule MR ≥ MC, explaining reasoning.
  6. Quick check (5') – Exit ticket: write one key difference between revenue in perfect competition and monopoly.
Conclusion:
Summarise how revenue measures and curves inform firm decisions in different market structures. Collect exit tickets to gauge understanding, and assign homework to calculate profit for a new data set using the formulas practiced today.
