The players are given one board each and placed so that either the words or digits are face up. Shuffle the number cards. Then one at a time, the number cards are picked up and read out aloud and then shown to the other players (if necessary). If the number spoken is on a player's board then that number is covered. The player who manages to cover all the numbers on his/her board first, wins. The teacher's booklet contains suggestions, tips and activities on how to play the game in different ways.
