Lesson Plan

• Describe the relationship between price and quantity demanded on a demand curve.
• Explain how a change in the price of a good produces a movement along the demand curve.
• Distinguish movements along the demand curve from shifts caused by non‑price determinants.
• Construct and label a demand‑curve diagram showing a movement between two price‑quantity points.
• Interpret a price‑quantity table to identify whether the change is a movement or a shift.

• Projector or interactive whiteboard
• Graph paper and coloured pens
• Printed worksheet with price‑quantity tables
• Whiteboard and markers
• Sticky notes for exit tickets

Begin with a quick “price‑drop” scenario for bread to capture interest. Ask students what they expect to happen to the amount bought when price falls, linking to their prior knowledge of demand curves. Explain that today they will learn how to illustrate this change on a diagram and how to tell it apart from a shift of the whole curve. Success will be measured by their ability to draw, label, and explain a movement along the curve.

1. Do‑now (5'): Students analyse a simple price‑quantity table and write one sentence on the observed change.
2. Mini‑lecture (10'): Review demand curve basics, define movement vs shift, display the suggested diagram (points A → B).
3. Guided modelling (12'): Teacher draws axes, plots points A (P=2.00, Q=100) and B (P=1.00, Q=200), adds arrow and label.
4. Pair activity (10'): Learners create their own diagram for the coffee example, label the movement, and check against a checklist.
5. Checklist discussion (8'): Whole‑class review of the “price change?” vs “non‑price determinant?” checklist to solidify distinction.
6. Formative exit ticket (5'): Each student writes a brief explanation for a new scenario (e.g., price of smartphones rises) indicating movement or shift.

Recap the key steps for drawing a movement‑along‑demand diagram and the checklist for distinguishing it from a shift. Collect exit tickets as a quick retrieval check. For homework, assign a worksheet with three additional price‑quantity tables for students to plot and classify the changes.
