## GETTING STARTED

The object of this game is to make the greatest product.

Place the deck of cards face down in the middle of the playing area. Any player draws a single card from the deck and places it face up. All players select a space on their gameboard. They write the number of the card in that space.

Players draw five more cards and proceed to fill in all the spaces on their gameboards.

Once all gameboard spaces are filled, players complete the multiplication. The player with the greatest product is the winner of that round. The winner earns 1 point. In the event of a tie, each player earns 1 point.

Example
Two completed gameboards using the six cards 2, 3, 4, 6, 7, and King (0) might look like this:

Player 1 has the greatest product and earns 1 point for this round. The winner is the player with the most points after a set number of rounds or a set time limit.

As players gain more experience with this game, they will develop strategies to maximize their chances of winning.

## VARIATION

Depending on multiplication skills being worked on, the number of cards used can be changed. Calculators may be used to check answers.
