This Flash-based game of chance helps children learn about the relationship between the positive and negative integers. Two players, one Positive, moving left to right, and one Negative, moving right to left, take turns rolling and adding two dice and moving a counter in their respective directions on the number line, with the goal of reaching their end of the number line (13 or -13). The game can be played with the applet or on paper (printable pdf included). A variation involving the choice of adding, subtracting, multiplying or dividing the two dice introduces strategic thinking. The Teacher' Notes page suggests strategies for introducing the game, questions to facilitate students' thinking, and a link to a simpler version of the game, Tug of War, cataloged separately.
