Tug of War

This Flash-based game of chance helps children learn to move along a number line either side of a central point, as a precursor to working with negative numbers. Two players, one Plus and one Minus, take turns rolling and adding two dice, and moving forward or backward in their respective directions on the line, with the goal of reaching their end of the line first (0 or 27). The game can be played with the applet or on paper (printable pdf included). A variation involving the choice of adding or subtracting 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 (Incey Wincey Spider) and a more advanced one (Tug Harder!), both cataloged separately.
