Description:

This interactive online game helps students develop fluency with identifying factors while fostering strategic thinking. A student can play against the computer or against a friend on a 6 by 6 grid containing the numbers 1-36. Each player in turn chooses a number from the board, and then the opponent claims all of its remaining proper factors. A player's score is the sum of all the numbers and factors she/he has chosen. When there are no numbers remaining with unclaimed factors, the game ends and the player with the greater total is the winner. This game is part of NCTM's Calculation Nation project (cataloged separately). Users may login as a guest and play against the computer, or register (free) to challenge other players online.
