30 Product

Formal Definition: Defining product in math, as Eula Ewing Monroe (1998) explained in Math Dictionary for Young People, “A product is the result of multiplication. Like 5×6=30, which is Factor × Factor= Product.”

Kid-speak: In mathematics, a product is a number or a quantity obtained by multiplying two or more numbers together. For example: 2 × 3 = 6. Here, the number 6 is called the product of 2 and 3. As another example, the product of 6 and 4 is 24, because 6 times 4 is 24.

Way to learn about product:

You can play a Product Game on the interactive applet adapted by National Council of Teachers of Mathematics to exercise your skill with products and multiples.

Object of the Game

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

How to Play

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.

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.

Player 1 moves either marker to another number, and the new product is colored blue for Player 1.

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.

Play continues until one player wins, or until all squares have been colored.
