Learning to identify prime numbers can be tricky. But this fun card game can make memorizing some basic prime numbers a breeze. Find a deck of cards and deal them out. We hope you can create a lot of prime numbers!

Before you start playing, review these important math concepts:

Prime number: A number for which the only 2 factors are itself and 1. The number 1 is not prime because it is classified as a unit. Prime numbers from 0–20 are 2,3,5,7,11,13,17 and 19.

Factor:  A number that divides evenly into another number

What You Need:

  • Deck of cards with the face cards removed
  • Pencil
  • Paper

What You Do:

  1. Shuffle the deck of cards and deal 6 cards to each player. Place the rest of the deck in the center of the play area.
  2. The objective of the game is for players to create an equation that results in a prime number using any number of cards in their hands. If a player can't make an equation, he loses his turn and must draw one card from the deck.
  3. Players are awarded one point for each card they use to create their equation. So the more cards players use, the more points they earn.
  4. The game continues until one player reaches 50 points.
