David Johnson 

December 2006, Volume 100, Issue 5, Page 56

The article from January of 1973 focuses on “element of surprise” -  effective teaching technique. Author discusses the subject matter noting that finding surprise in mathematics requires a new look and offers a list of sample problems containing such elements. Next he offers step-by-step classroom routine facilitating implementation of the technique. He concludes that element of surprise helps the teacher to uncover mathematics rather than cover the textbook.
