Presents 10 space-related ideas, thoughts, and questions represented on the Australian Association of Mathematics Teachers (AAMT) calendar. The ideas are on impossible shapes, fractals, space itself, galaxy, tesselated pigs, spirals, helices, black holes and three-dimensional surfaces, tesseracts, and mobius bands. (YP)

The corporation is owned and operated by a group of about 45 eighth graders, who make all the executive decisions concerning the sale of hot dogs and other foods at sporting events in the school. (MNS)

The Core-Plus Mathematics Project (CPMP) is a four-year program emphasizing mathematical modeling, featuring full use of graphing calculators, building on the theme of mathematics as sense-making, and involving investigations of real-life contexts that lead to reinventing important mathematics. (MKR)

Presents activities in which students study exponential growth and decay by collecting data, constructing graphs, and discovering algebraic formulas. (MKR)

Presents examples to illustrate how conditional probability statements can be used to introduce conditional probabilities, how early applications can be found in sports data, and how conditional probability can be related to data collection and presentation in two-way tables. (MKR)

Describes the use of glyphs, simple pictures or graphs whose parts represent information about a given subject, in a second-grade classroom. Includes many examples. (MKR)

Attempts to determine, using estimations and current power-law relationships, whether a newspaper report concerning the statement that a single 40,000-kg truck does as much damage to the highway as 9,600 cars is true. Provides a mathematical and graphical possible solution. (MVL)

Elementary education students (n=141) were asked to estimate answers to 25 arithmetic problems. Half were presented the problems in an application (word problem) format, and the other half received the same problems in a computational format. Results indicated higher success levels with the applied format which is contradictory to previous results…

Applies exponential growth and the speed of doubling times to the energy crises. Increases comprehension of this mathematical law and the significance of findings made through its use. Examines statements from authoritative sources on energy to illustrate the lack of understanding of arithmetic's relationship to the energy crisis. Suggests ways to…

Discusses the mathematics involved in comparing the purchase of an automobile with cash versus with a loan. Investigates two scenarios: (1) if a loan is taken out and the cash price is invested at a fixed rate, and (2) if cash is paid and monthly payments are invested over the period of the loan. (MDH)

Presents the theory of primary and secondary rainbow formation utilizing simple optics and geometric concepts. Describes an appropriate, waterless classroom demonstration and includes the relevant mathematical formulas and models. (JJK)

The actuarial profession is described to provide secondary school mathematics teachers insights into how actuaries use mathematics in solving real life problems. Examples are provided involving compound interest, the probability of dying, and inflation with computer modeling. (MDH)

Proposes that state legislatures are a laboratory for mathematics. Discusses the mathematics involved in the three income tax proposals submitted to the Connecticut General Assembly in 1991 and the effects that each plan would have on families. The proposals included a flat rate plan, a graduated rate plan, and a compromise proposal. (MDH)

Two properties of a wing, namely aspect ratio and wing loading, are described and the matrix approach is used to make certain deductions about particular wing plans. Some examples are provided which show how the matrix transformation of one wing plan into another brings about predictable changes in wing properties. (KR)

Presented is the problem of determining alternative schedules for major league baseball. Equations of the schedule, conditions on the solutions, and solutions are discussed. (CW)
