VIDEO TATA CARA PENGGUNAAN CONGKLAK KPK & FPB

Summary

This video explains how to use the congklak game to teach mathematics concepts like LCM (Least Common Multiple) and GCF (Greatest Common Factor). The presenter introduces the game, using two different-colored congklak seeds to demonstrate how to find the LCM of 2 and 5, resulting in 10. It then shows how to find the GCF of 10 and 20, identifying the common factors and concluding that the GCF is 10. The video combines fun and education, making mathematics learning interactive and engaging.

Takeaways

• 😀 The presentation introduces the team from Raden Fatah State Islamic University of Palembang, Group 13, in the Mathematics Education Study Program.
• 😀 The main topic of the demonstration is using the traditional game of congklak to teach mathematical concepts such as Least Common Multiple (LCM) and Greatest Common Divisor (GCD/FPB).
• 😀 The game of congklak is used with two different colors of seeds to represent two numbers in the demonstration.
• 😀 To find the LCM of 2 and 5, the multiples of each number are written: 2 (2, 4, 6, 8, 10, 12, etc.) and 5 (5, 10, 15, 20, etc.).
• 😀 The smallest common multiple between 2 and 5 is 10, which is identified by matching two seeds with different colors in the bowls.
• 😀 The demonstration emphasizes finding the lowest common multiple (LCM) by identifying the first matching multiples.
• 😀 The FPB (GCD) of 10 and 20 is found by identifying the factors of both numbers.
• 😀 The factors of 10 are 1, 2, 5, and 10, while the factors of 20 are 1, 2, 4, 5, 10, and 20.
• 😀 The highest common factor (FPB) between 10 and 20 is identified as 10 by matching the bowls with seeds of different colors.
• 😀 The final takeaway is that the FPB of 10 and 20 is 10, demonstrating the method of using congklak to visualize both LCM and FPB concepts in a hands-on way.

Q & A

What is the main focus of this video script?

The main focus of the video is to demonstrate how to use the traditional game of congklak to teach mathematical concepts, specifically the Least Common Multiple (LCM) and the Greatest Common Factor (GCF or FPB).

How does the game congklak help in finding the LCM and GCF?

Congklak is used in this video to visually represent and identify multiples for LCM and factors for GCF. The game’s colorful seeds and bowls allow students to visually match numbers and understand these mathematical concepts more clearly.

What numbers are used in the demonstration for finding the LCM and GCF?

The numbers used in the demonstration are 2 and 5 for finding the LCM, and 10 and 20 for finding the GCF.

How do the participants in the video find the LCM of 2 and 5?

The LCM is found by listing the multiples of 2 (2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24) and the multiples of 5 (5, 10, 15, 20). The lowest common multiple identified from both lists is 10.

What is the significance of using two different colors of seeds in the congklak game?

The two different colors of seeds represent the two different numbers (2 and 5 for LCM, 10 and 20 for GCF). This helps visually distinguish between the multiples and factors of each number, aiding in the identification of common multiples or factors.

Why is the number 10 chosen as the LCM of 2 and 5?

The number 10 is chosen as the LCM because it is the lowest number that appears in both the list of multiples of 2 and 5.

How is the GCF of 10 and 20 determined in the video?

The GCF is determined by finding the factors of 10 (1, 2, 5, 10) and the factors of 20 (1, 2, 4, 5, 10, 20). The highest common factor between the two lists is 10, so the GCF of 10 and 20 is 10.

What is the relationship between multiples and factors in finding the LCM and GCF?

Multiples are used to find the LCM (by identifying the smallest common multiple), while factors are used to find the GCF (by identifying the largest common factor). The game visually demonstrates this connection.

How does the video help in understanding mathematical concepts in a more interactive way?

The video uses the traditional congklak game as an interactive learning tool, making abstract concepts like LCM and GCF more tangible and engaging by physically interacting with the seeds and bowls.

What other mathematical concepts could be taught using the congklak game?

The congklak game can also be used to teach other concepts such as addition, subtraction, and division by manipulating the seeds and bowls, fostering a deeper understanding of basic arithmetic operations.
