ABSTRACT:
An apparatus and method for teaching mathematical expressions includes a plurality of four-sided members that represent the variables of factors of a mathematical expression. Each four-sided member has a different area representing a different variable in the mathematical expression. The apparatus enables a math student to visualize the rules that apply to mathematical expressions. The four-sided members include a first side having a first color and a second side having a second color, different from the first color, wherein the first side represents a positive number, and the second side represents a negative number. The four-sided members can be used for teaching by illustration simple multiplication and division, multiplication, division and factorization of polynomials, linear equations including inequations and absolute value, and systems of linear equations.
