Lesson Plan

• Define market share and market growth and explain their strategic importance.
• Calculate market share using the formula \(Market\ Share = \frac{Company\ Sales}{Total\ Market\ Sales}\times100\%\).
• Compute market growth rate between two periods using the appropriate formula.
• Interpret calculated figures to assess a company’s competitive position.
• Critically evaluate the limitations of market‑share and growth metrics.

• Projector and screen
• Whiteboard and markers
• Printed data tables of UK smartphone sales (2022 & 2023)
• Calculator worksheets for each student
• Formula reference handout
• Graph paper or digital graphing tool

Begin with a quick poll: “Which brand do you think dominates the UK smartphone market?” Use the responses to link prior knowledge of market competition. Explain that today’s success criteria are to accurately calculate market share and growth, and to discuss what these figures tell us about business strategy.

1. Starter – Do‑now quiz (5’) on basic marketing terms.
2. Direct instruction – Explain market‑share formula and work through the Alpha Phones example (10’).
3. Guided practice – Students calculate market share for each company using the worksheet (10’).
4. Introduce market‑growth formula and demonstrate with 2022‑2023 data (10’).
5. Independent practice – Calculate growth rate and answer a short analysis question (10’).
6. Class discussion – Review answers, highlight common errors, and explore the limitations listed in the notes (5’).
7. Exit ticket – Write one way a firm could use market‑share or growth data in its strategic planning (5’).

Summarise how market share and growth are measured and why they matter for strategic decisions. Collect exit tickets to gauge understanding, and assign homework: research a recent market‑share report for a chosen industry and calculate the growth rate for the past two years.
