Prime Factorization Guided Notes & Doodles | Factor Trees Prime Factors


Introduce prime numbers, composite numbers, and prime factorization using factor trees with this self-contained lesson! Includes guided notes with doodles, doodle math (similar to color by numbers), practice problems page, maze, and a real-life application. This resource works well as graphic organizer, scaffolded notes, and interactive notebooks. Student decompose composite numbers into the product of its prime factors, and then represent the answers using exponents (i.e. 125 = 5^3). Students also read about how prime factorization is used in encryption of credit cards to help connect math to real life.

⭐⭐⭐⭐⭐️ Christine M. - “I put this out as an extra credit assignment for my 8th graders at the end of the square and cube roots unit.  The students who chose to do it seemed to enjoy the "doodle" part because it was different than a typical color by number task.  Thank you!”
