Lesson Plan

• Describe the four main product‑extension strategies and their purposes.
• Compare the advantages and disadvantages of each strategy.
• Analyse a case study to select the most appropriate extension strategy.
• Evaluate how an extension strategy can affect sales and profit.
• Design a brief extension‑strategy plan for a given product.

• Projector and screen
• PowerPoint slides summarising each strategy
• Printed worksheet with case‑study table
• Extension‑strategy comparison handout
• Whiteboard and markers
• Exit‑ticket slips

Begin with a quick poll: “What new version of a product have you bought recently and why?” Connect this to prior knowledge of product life‑cycles. Explain that today’s success criteria are to identify, compare, and apply extension strategies to boost a product’s market performance.

1. Do‑now (5’) – Students list possible ways a familiar product could be extended; teacher collects ideas.
2. Mini‑lecture (10’) – Present the four extension strategies with real‑world examples using slides.
3. Guided analysis (15’) – In pairs, learners examine the case‑study table, decide which strategy fits best, and note pros/cons.
4. Whole‑class share (10’) – Groups present their choices; teacher highlights key comparisons.
5. Application activity (10’) – Individually, students complete an extension‑plan template for a product of their choice.
6. Exit ticket (5’) – Write one advantage and one risk of the strategy selected.

Summarise how each strategy can increase market share and the importance of monitoring results. Collect exit tickets to gauge understanding, then assign homework: research a real company that used an extension strategy and prepare a short summary for the next lesson.
