✔15 Unique Game Mats

✔15 Unique Decks of 16 Number Cards (240 total cards)

✔Answer Key for Easy Self-Check

Each student is given a game mat and a corresponding deck of 16 number cards. Students place the numbers on a triple Venn diagram based on their relationships as factors. Best of all, this product includes 15 versions for unlimited practice

For example: If the game mat is looking for Factors of 30, Factors of 36, and Factors of 40, the number "10" would go in the overlap between 30 and 40, the number "12" would go in the circle for 36, and the number "2" would go in the center where all three circles meet. The majority of the numbers in this game are less than 50 and the 15 versions get gradually more difficult so you can differentiate based on the needs of your students.

By sorting numbers this way, students more deeply understand the relationship between factors and multiples. This prepares them for whole number multiplication and division and for finding a common denominator when adding fractions.
