Kurikulum Merdeka Kelas 2 Matematika Bab 1 | Bilangan Lebih Besar Dari 100 | Halaman 1 - 12

Introduction

This tutorial provides a step-by-step guide to understanding larger numbers beyond 100, as outlined in the second-grade mathematics curriculum from the Kurikulum Merdeka. It is designed to help young learners grasp the concept of numbers greater than 100, with practical examples and exercises included.

Step 1: Understanding Numbers Greater Than 100

• Definition: Explain what numbers greater than 100 are. Any number that comes after 100 in the number line.
• Examples:
  • 101, 150, 200, etc.
• Visual Aid: Use a number line to illustrate numbers greater than 100.

Step 2: Comparing Numbers

• Concept: Teach how to compare numbers greater than 100.
• Techniques:
  • Use symbols such as > (greater than), < (less than), and = (equal to).
  • Example Comparisons:
    • 150 > 120
    • 200 < 250
• Activity: Provide a list of pairs of numbers for students to compare using the correct symbols.

Step 3: Number Patterns

• Identifying Patterns: Discuss patterns in numbers greater than 100.
• Common Patterns:
  • Even and odd numbers.
  • Counting by tens (110, 120, 130, etc.)
• Practice Exercise: Ask students to find the next three numbers in a pattern (e.g., after 100, 110, 120).

Step 4: Basic Operations with Larger Numbers

• Addition and Subtraction:
  • Explain how to add and subtract numbers greater than 100.
  • Example:
    • 120 + 30 = 150
    • 200 - 50 = 150
• Practice Problems: Create simple problems for students to solve.
  • Example Problems:
    • What is 135 + 25?
    • What is 160 - 70?

Step 5: Real-World Applications

• Application of Concepts: Discuss how understanding larger numbers is useful in everyday life.
• Examples:
  • Shopping (understanding prices).
  • Measuring distances (kilometers greater than 100).
• Activity: Have students list examples from their own lives where they encounter numbers greater than 100.

Step 6: Review and Reinforcement

• Key Takeaways: Summarize the main points learned about numbers greater than 100.
• Quiz: Conduct a short quiz or review session to reinforce learning.
• Discussion: Encourage students to share what they found interesting or challenging about the lesson.

Conclusion

Understanding numbers greater than 100 is crucial for developing mathematical skills in young learners. By practicing comparisons, operations, and real-world applications, students will build a solid foundation in mathematics. Encourage continued practice through exercises and real-life examples to reinforce these concepts. Consider exploring more advanced topics as students become comfortable with the material.
