Explore prime numbers and factorization with this beautiful set of cards.
Explore prime numbers and factorization with this beautiful deck of 54 cards, suitable for classroom or personal use. Each jumbo-sized square card displays a factorization diagram on one side, which visually represents the prime factorization of an integer, and the number itself on the other side. The deck contains the numbers 1-30, although many numbers have multiple cards corresponding to all the unique ways to order their prime factors. Use them as flashcards, organize them and look for patterns, or make up your own activities and games!
