Here's a prime factorization practice worksheet in which learners sharpen their problem solving skills as they solve six story problems.

Show how to factor four different numbers using a factor tree. This short slide show defines factoring and then shows how each number 28, 32, 33, and 30 can all be factored. 

Finding the prime factors of two numbers is the focus of this math instructional activity. Students write the factors to complete 2 factor trees, write the prime factorization for 9 numbers and answer 2 word problems.
