This incredible Bingo activity has 40 unique cards and two different versions of calling cards. It is a great activity for students just learning about prime factorization or for those that need a quick review.
The student Bingo cards contain composite numbers from 4-40. Each student card is unique. One version of the calling cards contains the prime factorization with exponents and the other version of calling cards contains the prime factorization without exponents. This makes the activity very versatile between grade levels.
You can use this activity with the entire class or use it in a small group setting. I like to put a student in charge of the calling cards (without the answer key). They get even more practice than the students playing Bingo.
Answer keys are always included.
