A Curious Number Pattern
Edwin G. Landauer · Mathematics Teacher Learning and Teaching PK-12 · 1984
In everyday life, mathematical curiosities often arise that can be used in the classroom to study the techniques of problem solving. These curiosities offer an interesting alternative to the traditional methods of attacking problems. Usually, our students are studying one type of problem, and therefore, the method of solving that problem becomes routine. When a problem arises from a source outside the classroom, however, a student may have to investigate several techniques before arriving at the appropriate procedure for a solution.
