Lesson Plan for Senior Secondary 2 - Economics - Concept Of Demand And Supply

Lesson plan for Senior Secondary 2 economics students on the topic "Concept of Demand and Supply": --- **Lesson Plan: Concept of Demand and Supply** **Grade Level:** Senior Secondary 2 **Subject:** Economics **Duration:** 90 minutes **Objectives:** 1. Students will understand the basic concepts of demand and supply. 2. Students will be able to define and explain the law of demand and the law of supply. 3. Students will analyze the factors that cause shifts in demand and supply curves. 4. Students will apply their understanding to real-world scenarios and graphs. 5. Students will recognize market equilibrium and the effects of changes in demand and supply on equilibrium price and quantity. **Materials Needed:** - Whiteboard and markers - Projector and computer - Graph paper and rulers - Copies of handouts and worksheets - Slide presentation for lecture - Real-world examples (e.g., news articles, case studies) **Lesson Outline:** **1. Introduction (10 minutes)** - Begin with a brief introduction to the topic by discussing why demand and supply are fundamental concepts in economics. - Pose an engaging question to the class such as, "Have you ever wondered why the prices of smartphones fluctuate?". - State the objectives of the lesson. **2. Definitions and Basic Concepts (15 minutes)** - Explain the definition of demand: the quantity of a good or service that consumers are willing and able to purchase at different price levels. - Explain the definition of supply: the quantity of a good or service that producers are willing and able to sell at different price levels. - Introduce the law of demand and the law of supply using simple language and examples. * Law of Demand: As the price decreases, the quantity demanded increases, ceteris paribus. * Law of Supply: As the price increases, the quantity supplied increases, ceteris paribus. **3. Demand and Supply Curves (10 minutes)** - Show how to graph demand and supply curves on a graph. - Illustrate movements along the curves versus shifts in the curves. * Movement along a curve: Due to changes in price. * Shift of a curve: Due to changes in non-price factors (e.g., consumer income, tastes, costs of production). **4. Factors Influencing Demand and Supply (20 minutes)** - Discuss factors causing shifts in the demand curve (e.g., income, tastes and preferences, prices of related goods, expectations, number of buyers). - Discuss factors causing shifts in the supply curve (e.g., production technology, input prices, expectations, number of producers, taxes and subsidies). - Use real-world examples to illustrate each factor. **5. Market Equilibrium (15 minutes)** - Define market equilibrium: the point where the quantity demanded equals the quantity supplied. - Show how equilibrium is represented on a graph where the demand curve intersects the supply curve. - Discuss what happens when there is a surplus or shortage in the market. - Explain the concept of equilibrium price and quantity and how markets self-correct. **6. Application Activity (20 minutes)** - Provide students with a set of graphs and scenarios to analyze. - Have students work in pairs or small groups to determine the effects of different scenarios on demand, supply, and equilibrium. - Scenarios should include: * A sudden increase in consumer income. * A technological advancement in production. * An increase in taxes on a specific good. * Changes in prices of substitutes or complements. **7. Review and Recap (10 minutes)** - Review the key points discussed during the lesson. - Invite students to ask questions and clarify any doubts. - Provide a summary of the core concepts: demand, supply, shifts in curves, and market equilibrium. - Hand out a short quiz or worksheet to assess understanding. **8. Assignment/Homework (Outside of Class Time)** - Assign students to find a current event article or news report that illustrates a change in demand or supply in a particular market. - Instruct them to write a brief report explaining how the event affects demand or supply and what the likely market outcome will be. **Assessment:** - Participation in discussions and activities. - Accuracy and completeness of worksheet answers. - Quality of the written report based on the current event article. --- **Note:** Adjustments can be made based on class size, available resources, and students' prior knowledge of the topic.
