ABSTRACT:
A method is provided for teaching and learning multiplication wherein unit power of ten values are assigned to strips of transparent material. The strips are positioned on a multiplication table array over the rows and columns representing the digits of the numbers to be multiplied. The color of the strip determines the unit value of the digits. By multiplying the value of each array element on that intersection of two strips by the unit value of the composite color formed by the overlying of the two strips and summing the products of the digit values and the unit values the final value of the numbers to be multiplied is obtained.
