Introduction

Duration: (10 - 15 minutes)

🎯 Purpose: This stage's goal is to lay a solid foundation for understanding multiples and divisors. By providing clear definitions and clarifying their differences, students will be ready to use these concepts in practical problem-solving, enhancing their understanding and ability to tackle future questions about multiples and divisors.

Did you know?

💡 Curiosity: Did you know that multiples and divisors even play a role in how we organise calendars and structure time? For example, the number 7 is a divisor of 28, which is why we have weeks consisting of 7 days! Additionally, multiples are used in sports for structuring tournaments and in music for crafting rhythms and beats.

Contextualization

🔍 Context: To kick off the lesson on divisors and multiples, share with the students that these concepts are crucial in mathematics and are frequently encountered in everyday life. For instance, when we want to share things equally among friends or when we explore patterns in sequences of numbers. Grasping multiples and divisors enables us to tackle problems more effectively and logically.

Concepts

Duration: (55 - 60 minutes)

🎯 Purpose: This stage aims to enhance students' comprehension of multiples and divisors through clear examples and in-depth explanations. By exploring the differences between these concepts and how they apply in real life, students will be better positioned to solve mathematical problems involving multiples and divisors. The suggested questions will allow students to put their knowledge into practice, reinforcing their understanding of the topics discussed.

Relevant Topics

1. 🔢 Definition of Multiples: Explain that multiples of a number are the outcomes of multiplying that number by integers. For example, the multiples of 3 are 3, 6, 9, 12, and so on. Highlight that multiples are infinite, and every number is a multiple of itself.

2. ➕ Definition of Divisors: Clarify that divisors of a number are the integers that can divide that number cleanly, without a remainder. For instance, the divisors of 12 are 1, 2, 3, 4, 6, and 12. Demonstrate that the divisors of a number are limited, and every number is a divisor of itself.

3. 🔄 Difference between Multiples and Divisors: Clearly explain the difference by stating that a multiple of a number is found via multiplication, while a divisor is a number that divides another without resulting in a remainder. Use examples to illustrate the distinction.

4. 📊 Practical Applications: Provide everyday examples where multiples and divisors come into play, such as when dividing groups, scheduling tasks, and recognising patterns in number sequences. Emphasise the significance of these concepts in mathematics and daily life.

To Reinforce Learning

1. List the first five multiples of 7.

2. Find all the divisors of 18.

3. What distinguishes a multiple from a divisor? Provide an example of each.

Feedback

Duration: (20 - 25 minutes)

🎯 Purpose: This stage aims to review and solidify students' understanding of multiples and divisors. By examining the answers to the questions in detail and prompting students with reflective questions, the comprehension of concepts is reinforced, enabling practical application of the knowledge in various contexts. This stage ensures students gain a clear and robust understanding of the distinctions and applications of multiples and divisors.

Diskusi Concepts

1. List the first five multiples of 7.

To find the multiples of 7, you simply multiply 7 by consecutive integers. Therefore, the first five multiples of 7 are: 7, 14, 21, 28, and 35. Remind them that multiples are infinite, with each number having specific multiples extending infinitely. 2. Find all the divisors of 18.

To identify the divisors of 18, you need to find all the integers that divide 18 without leaving a remainder. The divisors of 18 are: 1, 2, 3, 6, 9, and 18. Discuss that divisors are specific and limited to each number, and one can check divisibility through exact division. 3. What is the difference between a multiple and a divisor? Provide an example of each.

Reinforcing the class explanation, a multiple of a number comes from multiplying that number by integers, while a divisor is a number that divides another cleanly without leaving a remainder. For example, 20 is a multiple of 5 (since 5 x 4 = 20), and 5 is a divisor of 20 (because 20 ÷ 5 = 4, with no remainder).

Engaging Students

1. What would be the next multiple of 7 after 35? 2. Among the numbers 1 to 20, which number has the most divisors? 3. If we divide 15 equally among 3 friends, how many parts will each get? Why? 4. Think of a number that is a multiple of 4 and a divisor of 24. What is that number?
