Lesson Plan

• Describe how each non‑price determinant shifts the supply curve.
• Explain the difference between an extension and a contraction of supply.
• Analyse real‑world scenarios to identify the determinant and predict the direction of the shift.
• Apply the exam checklist to construct a complete answer for supply‑shift questions.

• Projector and screen
• Whiteboard and markers
• Printed handout of the determinants table
• Case‑study cards (e.g., input‑price fall, technology upgrade, tax increase)
• Sticky notes for quick responses

Begin with a quick poll: “If the price of wheat drops, what happens to the amount of bread produced?” Use the responses to link prior knowledge of the supply curve to the idea of whole‑curve shifts. State that today students will learn to distinguish extensions from contractions and will be able to explain why each occurs. Success will be measured by correctly identifying determinants and using the exam checklist.

1. Do‑now (5’) – Students match a list of determinants to “extension” or “contraction” on sticky notes and display them.
2. Mini‑lecture (10’) – Review the definition of supply, then introduce the difference between a movement along the curve and a shift of the curve.
3. Table analysis activity (12’) – In groups, complete a blank version of the determinants table with real‑world examples.
4. Case‑study role‑play (10’) – Each group receives a scenario card, decides the direction of the shift, and presents their reasoning.
5. Whole‑class discussion (8’) – Compare group answers, emphasise the exam checklist points.
6. Quick quiz / exit ticket (5’) – Students write one determinant, the type of shift, and a brief explanation on a slip of paper.

Recap the key determinants and how they cause extensions or contractions, linking back to the opening poll. Collect the exit tickets as a formative check and remind students to complete a short worksheet at home that asks them to identify shifts in three new scenarios.
