This article describes an activity that involves the use of simulation for decision-making. It is useful for demonstrating concepts in probability and statistics. (Contains 4 figures and 2 tables.)

Application of the integral calculus to predicting supplies of oil in future years is described. (SD)

Curve stitching activities can be used to motivate calculus students. The problem described here involves showing that a given envelope of a curve is parabolic. (SD)

The probabilities of six-card poker hands are derived and compared to those of the five-card poker hands. (JT)

Meterological information is used to develop a mathematical function resembling the sine function. (JT)

Shows a direct solution for factoring trinomials, without trial and error, using a calculator. When a calculator is not available, the mathematical chore is eased somewhat using reference tables, as shown in two noncalculator methods (determining nonfactorability and factorability). (JN)

"Root multiples" are defined, and problems involving "root multiples" are explored. (DT)

An approach to absolute value is described which emphasizes the metric property of the absolute value function and the fact that the real number form an ordered set. (DT)

Instructional techniques and examples of some of the mathematics problems used in a remedial college mathematics course for disadvantaged students are described. (DT)

Presented is a study that underscores the extent to which students do not understand the use or meaning of letters in equations. (MP)

The objectives, content, and intent of an undergraduate mathematics course at the University of Northern California. The course focuses on gambling and bets, with the focus of ideas on probability, expected value, computers, and the mathematics of finance. (MP)

Develops a general computer algorithm to obtain a magic square having a number of rows that is a multiple of four. Presents a BASIC program and sample runs. (YP)

Presents classroom curriculum and student projects that use dynamical systems--something that changes over time, such as weather or populations--to capture students' attention. (MKR)

Similarity of parabolas and other conic sections is discussed. The theorem "Any two parabolas are similar" is deduced. (SD)

An approach to precalculus mathematics allows students to pace themselves through the material. The approach is evaluated in terms of student performance, cost effectiveness and affective criteria. (SD)
