Ladder Method

Worksheet Description

This worksheet is about the prime factorization of numbers using the Ladder Method, also known as the Factor Tree Method. It provides a structured way to break down numbers into their prime factors through a step-by-step division process. The worksheet offers an example with the number 64 already factored into 2 x 2 x 2x 2x 2x 2. The students are then expected to apply the Ladder Method to other provided numbers, such as 80, 90, 72, 120, and 150, by dividing each number by its smallest prime factor until only prime numbers are left.

The worksheet is teaching students a systematic approach to finding prime factors of numbers, which is a key skill in number theory and arithmetic. It helps them understand how every composite number can be expressed as a product of prime numbers. The Ladder Method specifically aids in visualizing the factorization process and provides a clear, step-by-step guide to breaking down numbers into primes. This exercise not only reinforces multiplication and division skills but also enhances problem-solving abilities and prepares students for more complex mathematical concepts involving factors and multiples.
