### **Lesson Outline:**
#### **Introduction (10 minutes):**
1. **Greeting and Roll Call:**
- Start with a brief greeting and take attendance.
2. **Hook:**
- Pose a question to the class: "Imagine you started a small business, how would you measure the money you make from sales?"
3. **Objective Overview:**

#### **Main Content (35 minutes):**
1. **Introduction to Revenue Concepts (10 minutes):**
- Define **Total Revenue (TR)**: The total income from the sale of goods or services. TR = Price × Quantity.
- Define **Average Revenue (AR)**: The revenue earned per unit of output sold. AR = TR / Quantity.
- Define **Marginal Revenue (MR)**: The additional revenue earned from selling one more unit of output. MR = Change in TR / Change in Quantity.
- Illustrate these concepts using simple numerical examples and real-world analogies (e.g., a lemonade stand).
2. **Graphical Representation (10 minutes):**
- Demonstrate how to plot TR, AR, and MR curves on a graph.
- Explain the shapes and slopes of these curves under perfect competition and imperfect competition scenarios.
- Emphasize the significance of these curves in making production and pricing decisions.
3. **Class Activity: Solve Sample Problems (15 minutes):**
- Distribute handouts with sample problems related to TR, AR, and MR calculations.
- Solve one sample problem as a class to demonstrate the step-by-step process.
- Divide students into small groups and have them solve the remaining problems.
- Walk around the classroom to assist students and answer any questions.
#### **Conclusion (10 minutes):**
1. **Review and Recap:**
- Summarize the key points covered:
- Definitions and formulas of TR, AR, and MR.
- The importance of understanding these concepts in business and economic decision-making.
2. **Questions and Answers:**
- Open the floor for any questions or clarifications.
- Encourage students to relate these concepts to real-life examples they might be familiar with.
3. **Assignment:**
