### Lesson Plan: Concept of Demand and Supply (Advanced)
#### Grade Level:
Senior Secondary 2 (11th Grade)
#### Subject:
Economics
#### Duration:
90 minutes
#### Objective:
By the end of the lesson, students will be able to:
1. Understand the law of demand and supply.
2. Differentiate between movement along and shift of the demand and supply curves.
3. Analyze factors that cause shifts in demand and supply.
4. Evaluate the equilibrium price and quantity in a competitive market using demand and supply curves.
#### Materials Needed:
- Whiteboard and markers
- Projector and computer
- PowerPoint slides
- Graph paper and rulers
- Markers or colored pencils
- Handouts with practice problems
- Reading materials (textbook or articles)
#### Preparation:
- Prepare PowerPoint slides detailing the key concepts.
- Prepare handouts with graph paper and practice problems.
- Set up projector and ensure all technical equipment is working.
#### Lesson Activities:
**1. Introduction (10 minutes)**
- Begin with a brief review of the basic concepts of demand and supply covered in the previous lesson.
- Introduce the advanced concepts that will be covered today (movement along vs. shifts of curves, factors causing shifts, equilibrium analysis).
**2. Direct Instruction (30 minutes)**
- **Law of Demand and Supply:**
- Recap the basic laws: Law of Demand (inverse relationship between price and quantity demanded) and Law of Supply (direct relationship between price and quantity supplied).
- **Movement Along vs. Shift of the Curves:**
- Define and explain the difference between movement along the demand/supply curve versus a shift in the demand/supply curve.
- Use graphs to illustrate how a change in price causes movement along the curve, while changes in other factors cause shifts in the curve.
- **Factors Causing Shifts:**
- Demand-side factors: income, tastes and preferences, prices of related goods (substitutes and complements), future expectations, number of buyers.
- Supply-side factors: production technology, prices of inputs, prices of related goods in production, future expectations, number of sellers.
- **Equilibrium Analysis:**
- Explain market equilibrium, equilibrium price (market-clearing price), and equilibrium quantity.
- Illustrate how shifts in demand and supply affect equilibrium price and quantity (using graphical analysis).
**3. Guided Practice (20 minutes)**
- Distribute graph paper and have students draw demand and supply curves.
- Provide scenarios and ask students to illustrate movements along curves vs. shifts in curves.
- Discuss as a class the shifts that occur due to different factors (e.g., an increase in consumer income, an advancement in technology for production).
**4. Interactive Activity (15 minutes)**
- Divide students into small groups and provide each group with a set of "market" scenarios.
- Each group will identify how each scenario affects demand or supply, draw the new positions of the curves, and determine the new equilibrium price and quantity.
- Groups will present their findings to the class.
**5. Independent Practice (10 minutes)**
- Provide a set of practice problems as handouts.
- Students will individually work on these problems, applying their knowledge of shifts in demand and supply curves, and equilibrium analysis.
**6. Review and Q&A (5 minutes)**
- Summarize key points from the lesson.
- Address any questions or confusion from the students.
#### Assessment:
- Observe student participation during guided practice and interactive activities.
- Collect and review students' graphs and practice problem handouts to assess understanding.
- Conduct a short quiz at the end of the week to evaluate comprehension of the advanced concepts discussed.
#### Homework:
- Assign reading from the textbook or articles related to real-world applications of demand and supply.
- Provide additional practice problems involving shifts in demand and supply, and equilibrium analysis.
#### Reflection:
- After the lesson, note which areas students found most challenging.
- Adjust future lessons to address these areas and provide additional support where necessary.
