Did you know?

Did you know that ancient Egyptians used fractions thousands of years ago? They relied on them to measure land and divide harvests. Plus, in cooking, fractions are crucial for adjusting recipes based on the number of servings.

Contextualization

To kick off the lesson on fractions, explain to students that fractions are ways to express parts of a whole. Use relatable examples, like dividing a pizza among friends or sharing a chocolate bar. Highlight that fractions are essential in many aspects of life, including cooking, construction, and even sports.

Concepts

Duration: 40 to 50 minutes

The purpose of this stage is to elaborate on the concept of fractions and how to compute the fraction of whole numbers, ensuring that students’ comprehension is supported through clear explanations and practical examples. It also aims to help students compare fractions and tackle related problems, thereby reinforcing their understanding of the topic.

Relevant Topics

1. Understanding Fractions: Clarify that a fraction denotes a part of a whole. Use standard notation (numerator/denominator) and provide simple examples, like 1/2, 1/3, and 1/4.

2. Calculating the Fraction of a Whole Number: Show how to calculate a fraction of a whole number using practical examples, like 1/2 of 8 and 1/4 of 20. Explain the process of multiplying the numerator by the whole number and then dividing by the denominator.

3. Fraction Comparison: Illustrate how to compare fractions of the same quantity to grasp their relationships. For instance, compare 1/2 of 40 with 1/4 of 40 and explain the differing results.

4. Problem Solving: Introduce practical problems that involve finding the fraction of a quantity. Guide students through step-by-step solutions to ensure they understand the process.

To Reinforce Learning

1. What fraction represents half of 24? Solve and explain.

2. If you have 36 candies and want to share 1/3 with your friend, how many candies will they receive? Show your calculations.

3. Comparing the fractions 2/5 of 50 and 1/2 of 50, which one is larger? Justify your answer with calculations.

Feedback

Duration: 20 to 25 minutes

The goal of this stage is to review and solidify students' learning, providing an opportunity for reflection and discussion about the solutions presented. This helps clarify any uncertainties, reinforce concepts, and encourage active participation, making learning more collaborative and meaningful.

Diskusi Concepts

1. Discussion of the Questions 2. Question 1: What fraction represents half of 24? Solve and explain. 3. Answer: To find 1/2 of 24, multiply 24 by the numerator (1) and divide by the denominator (2). So, 1/2 of 24 is (24 * 1) / 2 = 12. 4. Question 2: If you have 36 candies and want to give 1/3 to your friend, how many candies will they receive? Show your calculations. 5. Answer: To find 1/3 of 36, multiply 36 by the numerator (1) and divide by the denominator (3). Thus, 1/3 of 36 is (36 * 1) / 3 = 12. 6. Question 3: Comparing the fractions 2/5 of 50 and 1/2 of 50, which one is larger? Justify your answer with calculations. 7. Answer: To find 2/5 of 50, multiply 50 by the numerator (2) and divide by the denominator (5). Therefore, 2/5 of 50 is (50 * 2) / 5 = 20. For 1/2 of 50, multiply 50 by the numerator (1) and divide by the denominator (2). Thus, 1/2 of 50 is (50 * 1) / 2 = 25. Comparing the two results, 25 is greater than 20, so 1/2 of 50 is larger than 2/5 of 50.

Engaging Students
