Two enrichment articles are presented; one dealing with finding partial fractions and reducing to polynomials; the other, with finding the heaviest object from eleven others of equal weight where all twelve are identical in appearance. (JG)

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)

A mathematical misteak" is an incorrect operation that leads to a correct result. An introduction to the use of the misteak" to emphasize the mathematical operations being taught. Examples and brief explanations of several types of misteaks" are given. (FL)

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)

Methods of finding the total number of gifts given in The Twelve Days of Christmas'' are described. (DT)

Modular arithmetic is used to show that there is at least one Friday the 13th in every year. A case-by-case proof is outlined and a proof of the general case is given. (DT)

Seven articles present: 1) a solution to a force equilibrium problem, 2) a magic square, 3) a characteristic of right triangles, 4) a family tree of Pythagorean triples, 5) a misunderstanding which may be cleared through modern mathematics, 6) a technique for solving conversion problems, and 7) a special permatation problem.
