Beasley, Guy L. – Mathematics Teacher, 1975
A three-digit number is chosen, the digits reversed, and the smaller is subtracted from the larger. The difference is a page number in the textbook; the teacher tells the last word on that page. The learning begins when the class uses algebra to prove why the teacher's trick works. (KM)

Curcic, Barbara – Mathematics Teacher, 1976
Thoughts of diverse individuals concerning mathematics are reprinted. Quotations are presented in four categories: philosophical, aesthetic and creative, emotional, and scientific. The author opines that the classroom use of such quotations can provoke thought about the nature of mathematics. (SD)

Vigilante, Nicholas; Kossack, Sharon – Journal of Reading, 1988
Describes techniques to integrate the reading of newspapers into mathematics instruction. (RS)

Travers, Robert; Kim, David – Mathematics Teacher, 1982
A method for finding the complex roots of a graph is detailed. A conjecture is made regarding the nature of zero points of fourth-degree polynomial functions, but it is not proven in general. Mathematical induction is viewed as a promising tool to prove the conjecture that turned out unproductive. (MP)

Porteous, Keith – Mathematics in School, 1986
Competitions at one high school are described: they try to attract as many participants as possible, not just excellent students. In one type, creativity is stressed; another is a tournament; a third involves problem solving activities. Examples are included. (MNS)
Descriptors: Creativity, Mathematical Enrichment, Mathematics Instruction, Problem Solving

Sullivan, Bob – Australian Mathematics Teacher, 1983
Comments on bells throughout history are noted. 'Change-ringing,' focusing on the sequence in which bells are rung, is then explored. (MNS)
