There are more pages and print options than what opens in preview. These festive factor trees can brighten up your classroom. Assign digits with multiple factors to students. Have them factor out the numbers to find the prime factorization. Then they can complete their tree! I have students use the red ornaments for the prime numbers so I can quickly check their work. If you use Macintosh Apple and have Pages I can send you the digital copy on request so students can do this assignment electronically! Contact me if you would like customized trees or if you have other questions. This activity goes along with Houghton Mifflin Math Chapter 14 Number Theory.
