Lesson Topic: interpret a product life cycle diagram
Learning Objective/s:
  • Describe the axes and stages of a product life cycle diagram.
  • Identify the current stage of a product by locating its position on the PLC curve.
  • Analyse how the shape of the PLC indicates sales trends and underlying factors.
  • Evaluate appropriate marketing strategies for each PLC stage.
  • Apply interpretation skills to a given PLC diagram in a brief written response.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed PLC diagram handouts
  • Markers and sticky notes
  • Worksheet with interpretation questions
  • Laptop with presentation slides
 Introduction:
Begin with a quick poll: Which everyday product do you think is in the decline stage? Review the concept of the product life cycle from previous lessons and outline today’s success criteria: students will accurately read a PLC diagram, determine the product’s stage, and suggest suitable marketing actions.
Lesson Structure:
  1. Do‑now (5’) – Students list three products they use and guess their PLC stage on a sticky note.
  2. Mini‑lecture (10’) – Explain axes, stages, and decision points using a projected diagram.
  3. Guided practice (12’) – Whole‑class walk through the five interpretation steps on a sample diagram; teacher questions for understanding.
  4. Independent activity (15’) – Students work on a worksheet to interpret a new PLC diagram and record stage, trends, and strategy.
  5. Peer review (8’) – Pairs exchange worksheets, check each other’s stage identification and give feedback.
  6. Whole‑class debrief (5’) – Summarise key cues for each stage and discuss common misconceptions.
Conclusion:
Recap the visual cues that signal each PLC stage and the linked marketing decisions. Students complete an exit ticket by writing the stage of a surprise product diagram shown on the board. Assign homework to find a real product, research its recent sales trend, and sketch a simple PLC diagram.
