This is a complete lesson with instruction and exercises about prime factorization, meant for 4th or 5th grade. It first briefly reviews what are primes, and then explains how to factor numbers using a factor tree. After several examples, there are many factorization exercises for the students.

In the last lesson, we found that the prime numbers less than 30 are 2, 3, 5, 7, 11, 13, 17, 19, 23, and One is usually not counted as a prime number.
