Lesson Plan: Percentage Word Problems

Subject: Mathematics

Grade Level: 5

Duration: 30 Minutes

Objectives

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

  1. Understand the concept of percentages.
  2. Solve word problems involving percentages.
  3. Apply percentage calculations in real-world scenarios.

Materials Needed

Introduction (5 minutes)

  1. Begin the lesson by asking students if they have ever heard the term "percentage." Gather a few responses.
  2. Explain that a percentage is a way to express a number as a fraction of 100. For example, 50% means 50 out of 100.
  3. Introduce the formula for calculating percentages:
    [ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]

Direct Instruction (10 minutes)

  1. Present a simple percentage example: "If there are 20 students in a class and 5 students are wearing glasses, what percentage of the class wears glasses?"
    • Show the calculation: [ \text{Percentage} = \left( \frac{5}{20} \right) \times 100 = 25\% ]
  2. Explain each component: the "part" is 5 (students wearing glasses), the "whole" is 20 (total students), and how to multiply by 100 to find the percentage.
  3. Write down a few more examples on the board, gradually increasing in difficulty:
    • "A store is having a sale. If a shirt originally costs $40 and is now 25% off, what is the sale price?"
    • "In a class of 30 students, 12 students scored above 80%. What percentage of students scored above 80%?"

Guided Practice (10 minutes)

  1. Hand out worksheets with word problems involving percentages.
  2. Walk the students through the first problem together as a class.
  3. Allow students to work in pairs on the remaining problems. Circulate the room to provide assistance as needed.

Independent Practice (3 minutes)

  1. Give students one problem to solve individually: "A farmer has 50 apples, and he gives away 20% of them. How many apples does he give away?"
  2. Allow them time to work it out.

Closing (2 minutes)

  1. Review the correct answers to the independent practice problem.
  2. Summarize the key points of the lesson:
    • Understanding percentages
    • How to calculate percentages through word problems
  3. Encourage students to think about where they might see percentages in everyday life, such as shopping sales, food labels, or sports statistics.

Homework Assignment

Instructions: Solve the following percentage word problems and show your work.

  1. A book costs $12 and is on sale for 20% off. What is the sale price of the book?
    Answer: $9.60

  2. A class of 25 students went on a field trip. If 15 of them were boys, what percentage are girls?
    Answer: 40%

  3. A sports team won 3 out of their last 10 games. What percentage of the games did they win?
    Answer: 30%

Conclusion

Encourage students to ask questions if they’re unsure about percentage concepts. Conduct a brief informal assessment through discussion on the accuracy of their homework results during the next class.
