In this multiplication worksheet, you'll get to practice identifying factors through the fun activity of creating factor trees. Factors, prime numbers, and composite numbers are explained. An example of a factor tree is provided, followed by five more numbers for students to create their own factor trees.

A factor tree is a fun way to determine what numbers multiply to make a bigger number. Imagine drawing a tree where you start with a big number at the top and then find two smaller numbers that multiply to get that big number. Then you keep breaking down those smaller numbers until you can't anymore because they are only divisible by themselves and 1 (these are called prime numbers). Factor trees help us see what numbers make up a big number and teach us how to find prime numbers, which are like the building blocks for all numbers.
