Introduction

Duration: (10 - 15 minutes)

This stage is crucial for ensuring that students clearly grasp the lesson's objective and understand what is expected of them by the end of the session. It provides a structured learning experience and encourages students to focus on the important elements of the content.

Did you know?

Did you know that being able to compare numbers helps us make decisions in our daily lives? For example, when we're at the grocery store, we compare prices to select the best deal. Or when we play a game, we count points to determine who's winning. Comparing numbers is a skill we utilize all the time!

Contextualization

To kick off the lesson on comparing natural numbers under 20, start by explaining to students that numbers are an essential part of our everyday lives. Incorporate simple and relatable examples, such as counting the number of pencils in a case, the number of students in the class, or even how many toys each child has. This context illustrates the topic's relevance and emphasizes the importance of understanding how to compare numbers.

Concepts

Duration: (40 - 50 minutes)

This stage is designed to deepen students' understanding of comparing natural numbers less than 20, ensuring they can identify the largest and smallest numbers in a set and arrange numbers in both ascending and descending order. It provides guided practice with clear examples to reinforce their understanding of the content.

Relevant Topics

1. Comparison of natural numbers: Explain that comparing numbers means determining which one is larger or smaller. Use straightforward examples, such as comparing 5 and 8. Illustrate that 5 is less than 8 because it comes first when counting.

2. Comparison symbols: Introduce the symbols > (greater than), < (less than), and = (equal to). Clarify that we use these symbols to compare numbers. For example, 3 < 7 indicates that 3 is less than 7.

3. Ascending and descending order: Explain how to arrange numbers in ascending order (from smallest to largest) and descending order (from largest to smallest). Use practical examples, like sorting the numbers 2, 9, 4, and 7 in ascending order (2, 4, 7, 9) and descending order (9, 7, 4, 2).

To Reinforce Learning

1. Compare the numbers 12 and 8. Which one is larger?

2. Arrange the numbers 3, 15, 7, and 1 in ascending order.

3. What is the smallest number among 10, 5, 19, and 14?

Feedback

Duration: (20 - 25 minutes)

This stage focuses on reviewing and consolidating students' understanding of comparing natural numbers less than 20. By discussing answers and engaging students in reflective questions, this section provides an opportunity to clarify doubts, reinforce key concepts, and ensure students feel confident in their number comparison skills.

Diskusi Concepts

1. To compare the numbers 12 and 8, one should observe which number appears first in the count. Since 8 comes before 12 on the number line, we conclude that 8 is less than 12. Therefore, 12 > 8. 2. To arrange the numbers 3, 15, 7, and 1 in ascending order, start with the smallest number and work your way to the largest. Begin with 1, followed by 3, then 7, and finally 15. The ascending order is 1, 3, 7, 15. 3. To identify the smallest number among 10, 5, 19, and 14, look for the number that appears first when counting. The number 5 comes before 10, 14, and 19. Hence, 5 is the smallest number.

Engaging Students

1. Ask students: 'Why is it important to learn how to compare numbers? Can you think of everyday situations where this skill is useful?' 2. Encourage students to come up with their own examples of comparing numbers and present them to the class. 3. Invite students to recall a situation where they had to compare numbers recently. Ask: 'How did you determine which number was larger or smaller?' 4. Suggest that students explain the process of ordering numbers in ascending and descending order to a classmate. This reinforces their learning through teaching.

Conclusion

Duration: (15 - 20 minutes)

This stage aims to review and consolidate the main points covered in the lesson, ensuring that students grasp the content and its practical implications. It reinforces learning and helps students feel confident in their number comparison skills.
