Factor Game

In this activity, students are engaged in a fun interactive game in which they must partner up to find factors of numbers that are displayed on a game board. One player colors any single number, while the second player must then color all the factors of that number. The student with the most colored boxes wins. This resource includes an activity sheet that will help students learn about the most effective strategy in this game, and also about the concepts of prime and composite numbers.
