📚 Topic Summary
Prime factorization is breaking down a number into its prime number building blocks. The ladder method, also called the division method, is a way to find those prime factors in a structured way. You keep dividing by prime numbers until you can't divide anymore. This method makes it super easy to see all the prime factors at the end! This worksheet will give you some practice! 🎉
🧮 Part A: Vocabulary
Match the term to its definition:

(Match: 1-A, 2-C, 3-D, 4-B, 5-E)
✍️ Part B: Fill in the Blanks
The ladder method, also known as the __________ method, helps us find the _________ ________ of a number. We start by dividing the number by the smallest _________ number that divides it evenly. We continue this process until the only number left is _________. Then, we multiply all the prime numbers we used as _________ to get the prime factorization.
(Answers: division, prime factors, prime, 1, divisors)
🤔 Part C: Critical Thinking
Why is the ladder method a useful tool for finding the prime factorization of a number? Explain in your own words.
