    Grade: 3rd to 5th, 6th to 8th

    The Product Game is a fun, interactive game that exercises your skill with factors and multiples.

    This interactive is optimized for your desktop and tablet.



    Object of the Game

    To get four squares in a row—vertically, horizontally, or diagonally.

    How to Play

    1. To begin the game, Player 1 moves a marker (green square) to a number in the factor list of numbers 1-9 along the bottom of the game screen.
    2. Player 2 then moves the other marker (green square) to any number in the factor list (including the number marked by Player 1). The product of the two marked numbers is determined, and that product is colored red for Player 2.
    3. Player 1 moves either marker to another number, and the new product is colored blue for Player 1.
    4. Players take turns moving a marker, and each product is marked red or blue, depending on which player made the product. However, if a product is already colored, the player does not get a square for that turn.
    5. Play continues until one player wins, or until all squares have been colored.
