This prime and composite board game requires no preparation. Just print, and add two dice and different colored chips for each player, and you are ready to use it right away.The first player rolls two dice and uses them to create a 2-digit number. They will decide if the number they created is prime or composite and cover up that word on the game board with one of their colored chips. A player can “bump” another player’s chip off a space unless the space is locked. To lock a space you must have two of your color chip on that space. The first player to use all of their chips is the winner. Numbers go up to 66. This was made for the fourth grade common core math objective 4.OA.4.
