A graphical representation is used to construct a line one centimetre in length. (MP)

Suggests using school planetariums to teach the use and interpretation of coordinate systems (maps, graphs). Also suggests that using music to correspond to specific points to be located stimulates student motivation. Provides a comprehensive list of sources of music. (KC)

A method for sketching functions and finding slopes and roots rising synthetic division is illustrated. (MK)

A theoretical foundation is provided for a method of identifying those books in a library's stack that determine any given percentage of the current circulation. Basic components and requirements of the technique are described, and the theory is applied in an example that manipulates data from a university library. (Author/MBR)

An example is given of a class of problems whose solutions require the use of a scientific calculator in order to plot the graphs. (MP)

An alternative approach is described for presenting the idea of the derivative through the use of chords of a graph. (MP)

Some of the questions used on a test covering concepts of graphing are presented, along with a selection of students' comments and percentages of students making given responses. (DT)

Provides directions for constructing graphical alignment charts to solve a variety of mathematical physics problems. (MLH)

A geometric approach to the solution of quadratic equations and more general polynomials is based on finding points with minimum distance from the x-axis. The approach is useful in motivating the definition of complex numbers. (SD)

Important demographic trends in the United States include 1) the population's changing age profile, 2) the tendency for young people to remain single longer, 3) the widening mortality differential between the sexes, and 4) reversal of migration trends. Available from: Elsevier Scientific Publishing Company, Box 211, Amsterdam, the Netherlands,…

Presents an activity that illustrates how data stored in a matrix or list can be plotted as a graph in the parameter plotting mode on graphic calculators. (ASK)

This article describes the organization and results of the 1990 New Zealand Children's Census. This census, which preceded a National Census, provided a powerful tool for raising statistical awareness nationwide. (Author)

Offers problems involving baseball to give students the opportunity to utilize the technology of a graphing calculator such as the TI-82 to work on the area of statistics. Gives step-by-step instructions as well as explanations. (AIM)

Cooperative groups were given transparencies of eight regular inscribed polygons and overlays of corresponding circumscribed polygons and were asked to find the perimeters and ratios of perimeter to diameter. Transparencies give students a graphic illustration of limits. Includes reproducible worksheet. (NI)

Reprints three items that appeared in the media that were developed into mathematical problems. Items include a commentary called Junk the Penny, a sale advertisement for a department store, and a sports column with statistics. Eighteen questions are provided along with answers. A graphing calculator is suggested for some problems. (PVD)
