Topic

Prime and Composite Numbers

Description

Divisibility by 8: A number is divisible by 8 if the last three digits are divisible by 8. For example, 8,312 and 9,064 are divisible by 8 because their last three digits form numbers that are divisible by 8. This rule adds a higher-level test for divisibility, which is useful for analyzing larger numbers and their factorization.

The mathematics behind this topic provides a foundation for understanding how numbers interact with one another. By exploring the patterns and properties of prime and composite numbers, students can develop critical thinking and problem-solving skills.

Teacher's Script: Let’s explore an important concept that involves classifying numbers based on their factors. This concept will help us understand how numbers are built and how they can be broken down into their basic building blocks. Pay attention to the visuals and explanations to see how these ideas connect to everyday math!
