# Factor Trees & Prime Factorization: practice & questions for non-prime #'s 1-15

### Description

Students build the first 9 factor trees to learn how to discover the prime factors of any number in a manageable method. To help students self-correct, if needed, there is an answer bank for them to work with.

Students are able to visually build their trees and then smoothly transition their knowledge to writing out the prime factorization of the number of each tree. Students then answer scaffolded questions about the prime factorization of the trees they have built. This activity is designed to gradually introduce new concepts related to prime factors: such as learning why different shaped trees for the same number will still have the same prime factors. This is a fundamental learning block for building up to many math skills, for example things like finding GCF and LCF.
