Two Methods to Teach Prime Factorization - Foldables and More

Two different visuals...you choose!

This packet explains two methods for prime factorization--The ‘tree method’ works from the top down and focuses on factors. The ‘birthday cake method’ works from the bottom up and focuses on division.
The tree method is most widely taught and used. It is the way you and your parents will be most familiar with. I have found, however, that the ‘birthday cake method’, while not as widely used, seems to be the method my students prefer and have the most success with.

I have created a packet that will provide you with the necessary resources, regardless of which method you decide to use with your students,

Included in this packet are two matchbook fold-ups--one for each method, a mini-book for each method and a two-sided practice page for each method. Detailed answer keys for practice pages and both mini-books are included as well.
