Lesson Plan: Investment Decision Rules

Subject: Mathematics

Duration: 60 Minutes

Grade Level: College

---

Lesson Overview

In this lesson, students will learn about various investment decision rules used to evaluate and compare investment projects. This includes the Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period methods. The lesson will consist of a lecture, real-world examples, and a group activity to reinforce their understanding.

Learning Objectives

By the end of this lesson, students will be able to:

1. Understand the basic concepts of investment decision rules.
2. Calculate NPV, IRR, and Payback Period for various investment scenarios.
3. Apply these decision rules to evaluate potential investments.

Materials Needed

• Whiteboard and markers
• Projector and presentation slides
• Financial calculators or software
• Handouts with investment scenarios and formulas

Lesson Outline

Introduction (10 Minutes)

• Greeting and Attendance: Welcome students and take attendance.
• Lesson Objectives: Briefly explain the objectives of the lesson.
• Importance of Investment Decision Rules: Discuss why understanding these rules is crucial for making informed financial decisions.

Theoretical Framework (20 Minutes)

1. Net Present Value (NPV):

   • Definition: Explain what NPV is and how it reflects the value of future cash flows in today's dollars.
   • Formula: [ NPV = \sum \left( \frac{C_t}{(1+r)^t} \right) - C_0 ] Where (C_t) is the cash inflow during the period, (r) is the discount rate, and (C_0) is the initial investment.
   • Example: Provide an example with numbers and calculate the NPV.

2. Internal Rate of Return (IRR):

   • Definition: Clarify what IRR is and how businesses use it to make investment decisions.
   • Example: Illustrate how to find the IRR using trial and error or financial calculators.
   • Importance of comparing IRR with the cost of capital.

3. Payback Period:

   • Definition: Explain how the Payback Period measures how long it will take for an investment to generate cash flows sufficient to recover the initial investment.
   • Formula: [ Payback \, Period = \frac{Initial \, Investment}{Annual \, Cash \, Inflow} ]
   • Example: Work through a simple calculation with the class.

Group Activity (20 Minutes)

• Group Exercise: Divide the students into groups and provide them with a scenario involving a potential investment.
• Task: Each group will compute NPV, IRR, and Payback Period for their assigned scenario and present their findings to the class.

Review and Discussion (10 Minutes)

• Class Discussion: Encourage students to discuss the results of their calculations and what factors influenced their decisions.
• Address any questions or clarifications needed regarding the decision rules.

Homework Assignment

Instructions

Complete the following tasks based on the scenarios provided. Show your work for full credit.

Tasks

1. You are considering an investment that requires an initial payment of $10,000. This investment is expected to generate cash inflows of $3,000 at the end of each year for the next 5 years. If the discount rate is 8%, calculate the NPV of the investment.

2. Using the same investment scenario above, calculate the IRR.

3. Calculate the Payback Period for the investment.

Correct Answers

1. NPV Calculation: [ NPV = -10000 + \left( \frac{3000}{(1+0.08)^1} + \frac{3000}{(1+0.08)^2} + \frac{3000}{(1+0.08)^3} + \frac{3000}{(1+0.08)^4} + \frac{3000}{(1+0.08)^5} \right) \approx -10000 + 10923.19 \approx 923.19 ] NPV ≈ $923.19

2. IRR Calculation: (Trial and error method or using a financial calculator)

   • Approximate IRR ≈ 10.5%

3. Payback Period Calculation: [ Payback \, Period = \frac{10000}{3000} \approx 3.33 \, years ] Payback Period ≈ 3.33 years

Conclusion

Wrap up the lesson by reiterating the importance of investment decision rules in financial analysis and decision-making. Encourage students to think critically about investment opportunities they may encounter in their future careers.
