When one method isn't enough to teach GCF, try two! This interactive webpage introduces factors and the prime factor tree to find the greatest common factor of two numbers. After the lesson, have learners click to try the two examples...

Deepen the number sense of young mathematicians by exploring the process of prime factorization. Follow along with this step-by-step presentation that explains how factor trees are used to break a composite number down into its prime...

Find the common denominator between prime factors, factor trees, and the distributive property. Scholars learn to find the least common multiple and greatest common factor of pairs of numbers. They rotate through stations to connect...

Incorporate riddles into your math lesson by having students make tree factors and determine if the number is a prime or composite. They will also use other clues to find the answer to the riddle while sharpening their...

RJ instructs your sixth graders in two different methods of determining least common multiples. The first is by listing several multiples of each number, and the second is by drawing factor trees. This is an ideal flipped classroom...

Young mathematicians discover trees organize more than just families — they help factor, too. The lesson plan begins with factor trees and develops slowly to factoring by grouping and special patterns.
