  • 4-digit place value
  • decimal place value


The goal of this game is to create the largest number possible.

Place the deck of cards face down in the middle of the playing area.

Player 1 draws a card from the deck and places it face up. All players must write this number down on their gameboard. Players may choose any place value position on their board.

Players draw five or more cards, one at a time, and fill in their boards; they choose what they believe to be the best possible place-value position for each number. Once players write a number on their grids that number cannot be erased.

At the end of the round, the player with the largest number earns 10 points.

  • Player 1 uses the cards drawn to create the number 9, 652.41
  • Player 2 uses the cards drawn to create the number 9, 564.21
  • Player 1 has the larger number. She wins the round and earns 10 points.
Play until one player achieves 100 points.
