Factors with Prime and Composite Numbers (2 of 2)
Ten two-digit numbers are listed for fourth graders to factor. Once they have factored each, they circle whether the original number is prime or composite. If you click on the "Print Worksheet" button, the printable spreads the problems unnecessarily over two pages. You may want to simply copy them onto your own document in order to save paper. A bonus is that the answers are available via another click of a button.
