Soon all of our intermediate-algebra stu dents will be using electronic calculators. The teaching of interpolation and compu tation using logarithms will be a thing of the past. How shall we gainfully replace this material? Many suggestions shall be

In his book A Survey of Geometry, Howard Eves (1966, 183) states, “The Greek geometers of antiquity devised a game— which judged on … [challenge, variety and simplicity] must surely stand at the very top of any list of games to be played alone.

In “A Unification of Two Famous Theorems from Classical Geometry” (1979), Eli Maor developed a relationship between two theorems: If two chords intersect within a circle, the product of the segments of one is equal to the product of the segments

As teachers of mathematics, we should continually seek new and better methods of dealing with the particular problems of each topic that we are asked to teach. We assume that the methods that were taught to us or those presented in the textbooks that
