Procedure:
1. Introduction (10 minutes)
a. Begin the lesson by asking students if they have heard or used the term "percentage" before. Discuss any prior knowledge they may have.
b. Explain that percentages are a way to express a part of a whole as a fraction of 100. For example, 50% means 50 out of 100.
c. Provide simple real-life examples of percentages, such as sharing a pizza or dividing candies among friends.
2. Understanding Percentages (15 minutes)
a. Write the following equation on the board: x% = x/100. Explain that this equation shows the relationship between a percentage and its equivalent fraction.
b. Demonstrate how to convert a percentage to a fraction and vice versa using simple examples. Encourage students to ask questions and participate in the discussion.
c. Provide additional examples for students to practice converting between percentages and fractions.
3. Calculating Percentages (20 minutes)
a. Explain that percentages can also be used to calculate a part of a whole or find the whole when given a part and the percentage.
b. Introduce the formula: Part = (Percentage/100) x Whole. Explain that this formula can be used to find the part or the whole, depending on the given information.
c. Solve a few simple problems together as a class, demonstrating how to use the formula. Encourage students to share their strategies and solutions.
d. Distribute worksheets with simple percentage problems for students to solve individually or in pairs. Walk around the classroom to provide assistance as needed.
4. Real-Life Applications (10 minutes)
a. Discuss real-life scenarios where percentages are commonly used, such as calculating discounts or sharing items among a group.
b. Ask students to brainstorm other situations where percentages are relevant, such as calculating grades or dividing a budget.
c. Have students share their ideas and discuss how percentages are used in these scenarios.
5. Conclusion and Review (5 minutes)
a. Summarize the key concepts covered in the lesson, including converting between fractions, decimals, and percentages, as well as calculating simple percentages.
b. Review any challenging problems or concepts that students struggled with during the lesson.
c. Encourage students to practice calculating simple percentages in their daily lives and provide resources for further practice if available.
