Give an Equation
The leader of the game will give a multiple equation to the players. Depending on the desired difficulty level, the equation can be shown to the players on a piece of paper or simply called out orally. To speed up the tempo of the game, the leader may place a limit on the number of times that the equation is called before moving on to the next one. The leader should place the card aside in order to prevent repeating the same equation during the game.
Look for an Answer
Once the players have been given the equation, it is time for them to look for an answer. The answer on the card can be written as a numeral, as a number word or as pictures representing numbers. The number that the player looks for must match the correct answer for the equation. Only one answer may be covered per equation.
Win the Game
When a player has a straight line of squares covered, the game is won. The line may be vertical, horizontal or diagonal. Each covered square in the line must correspond with a given equation. Once the player recognizes that he or she has completed a straight line of squares, the player must call out "bingo" in order to indicate that he has won. If the squares covered are found to be correct, the player wins.
