Lesson Plan

• Describe the non‑price determinants that cause the supply curve to shift.
• Explain how each determinant influences the direction of the shift.
• Analyse a supply function to predict the effect of a change in a determinant.
• Apply knowledge to interpret diagrams showing rightward or leftward shifts.
• Evaluate the impact of government policies (taxes, subsidies) on market supply.

• Projector and screen
• Whiteboard and markers
• Printed handout of the determinant table
• Supply‑curve diagram worksheet
• Sticky notes for exit tickets
• Calculators (optional)

Begin with a quick poll: “If the cost of raw materials falls, what happens to the amount firms are willing to sell?” Connect this to students’ prior knowledge of the basic supply curve, then outline that today they will identify all factors that move the entire curve and how to predict the direction of those moves.

1. Do‑now (5') – short recall quiz on the price‑quantity relationship of the supply curve.
2. Mini‑lecture (10') – present the eight non‑price determinants with examples, using slides.
3. Paired activity (15') – fill a table indicating whether each determinant causes a rightward or leftward shift and justify the reasoning.
4. Graphing exercise (10') – plot the original supply curve (S₁) and a shifted curve (S₂) after a technological improvement.
5. Case‑study discussion (10') – analyse a real‑world scenario (e.g., new tax on cigarettes) and predict the supply shift.
6. Formative check (5') – exit ticket on a sticky note: name one determinant and state the direction of its shift.

Summarise that supply shifts occur when any non‑price factor changes, highlighting the direction rules. Collect exit tickets to gauge understanding, and assign a homework task to find a recent news article describing a supply‑side change and explain the expected shift.
