Creating Factor Pair "Trees"

In this lesson, students will practice identifying factor pairs of whole numbers. Students will then draw a triangle around their factor work so that it resembles a triangular tree. Students will then circle all of the prime numbers inside the tree. The circles might represent the balls or ornaments on a holiday tree if doing this lesson around the holidays. This lesson does not teach an understanding of factors or prime numbers but is, rather, a practice of the students' knowledge of these concepts.
