PRE- REQUISITE KNOWLEDGE:

Students should have a strong foundation in basic arithmetic operations, including addition, subtraction, multiplication, and division. They should be comfortable working with whole numbers, decimals, and fractions.

Students should understand the concept of percentages and how to convert percentages to decimals and fractions. This will be crucial for calculating discounts and determining profit or loss percentages.

A basic understanding of ratios will be helpful as some problems may involve using ratios to calculate cost prices, selling prices, or discount amounts.

Concepts of Buying and Selling: Some familiarity with the concepts of buying and selling goods or products will make it easier for students to relate to real-life scenarios involving profit, loss, and discount.

MATERIALS:

Whiteboard and markers, Handouts with practice problems, Real-life scenarios for application exercises

LEARNING OBJECTIVES:

• To introduce students to the concepts of profit, loss, and discount.
• To enable students to solve problems related to profit, loss, and discount.
• To enhance students' critical thinking and problem-solving skills through real-life scenarios.

LESSON PLAN PROCEDURE

INTRODUCTION

Begin the class by asking students if they have ever bought or sold something, and whether they encountered any situations where they gained or lost money.

Introduce the concepts of profit, loss, and discount, and explain how they are essential in everyday transactions.

Provide real-life examples of profit, loss, and discount to help students understand the relevance of these concepts.

UNDERSTANDING PROFIT, LOSS, COST PRICE & SELLING PRICE

Define profit and loss and explain the difference between the selling price and the cost price. 

Demonstrate how to calculate profit and loss using the following formulas:

Profit = Selling Price - Cost Price

 Loss = Cost Price - Selling Price 

Solve a few practice problems together on the whiteboard.

Demonstrate how to calculate profit% and loss% using the following formulas:

 

 

Demonstrate how to calculate  Selling Price (S.P.) using the following formulas:

When Profit Percent is given

When Loss Percent is given

 

Demonstrate how to calculate Cost Price (C.P.)  using the following formulas:

Cost Price when Profit Percent is given

 

When Loss Percent is given

 

PRACTICE EXERCISES

a. Hand out practice problems to students.

b. Let students work on the problems individually or in pairs.

c. Provide assistance to students who need help.

REVIEW

Start the class by revisiting the concepts of profit and loss.

Ask a few students to solve practice problems on the whiteboard to reinforce understanding.

INTRODUCTION TO DISCOUNT

Explain what a discount is and how it affects the selling price.

Illustrate how to calculate the selling price after applying a discount using the formula:

 

Illustrate how to calculate the Marked price after applying a discount using the formula:

 

Illustrate how to calculate the Discount %

Show examples of discounts in real-life scenarios.

PRACTICE EXERCISES

Provide additional practice problems related to discounts.

Encourage students to solve them on their own or in groups.

Monitor their progress and address any difficulties they encounter.

APPLICATION OF CONCEPTS

Present students with real-life scenarios involving buying and selling with profit, loss, and discounts.

Divide the class into groups and have them analyze the situations and calculate the outcomes.

Allow each group to share their approach and solutions.
