Object of the Game Make arrays to cover more squares than the other player.

Materials

- 2 number cubes labeled 1-6
- 1-centimeter grid paper
- crayons

Number of Players 2

**How to Play**

(1) Player 1 tosses the number cubes. One cube shows the number of rows. One cube shows the number of columns.

(2) Player 1 shades an array on grid paper using the numbers tossed.

(3) Player 2 repeats Steps 1-2 using a different color to shade the array tossed. The players take turns tossing the number cubes and shading arrays using uncolored squares only. If there are not enough uncolored rows and columns to color an array, that player’s turn ends.

(4) Play continues until each player has had 5 turns. The player with more squares shaded is the winner.

Answer: This is a game to learn about rows and columns
