The rule that "the product of two negative numbers is positive" is one of the earliest stumbling blocks that convince many students that mathematics means memorizing, not reasoning. Appropriate experience with counting games can restore intuition to the rules of negative numbers. Board games help students appreciate the value of scoring, first with simple addition (especially where movement depends on the throw of a pair of dice) and later in more complicated games where the score can be positive or negative.

Recently modern physics has become much more complicated. Some current models keep track of seven dimensions that act like space and four that act like time, to give an 11dimensional configuration space. Another important model uses a configuration space with 26 dimensions. In each case the choice of the model depends to some degree on the kinds of mathematics that apply in these dimensions, as an aid to keeping track of the complex interrelationships among events in these high-dimensional spaces.

Fractals can be used to motivate a large number of mathematical discussions.
