Compares observed to expected counts of white, African American, and Hispanic major-league baseball players (n=650) in 1989. Uses chi-square values to determine that racial differences are highly significant for pitcher, catcher, shortstop, and outfielder. Includes appendix with 1993 player counts and seven suggested student activities. (SEW)

Practical decisions involving fuel economy are shown to require important skills from secondary school algebra and analysis. (MP)

This experiment designed for beginning physics students, is related to postal regulations restricting the size of envelopes. A graph is constructed that allows for testing the mailability of envelopes. (MP)

Describes an activity in which students analyze data from the Olympics. Discusses assessment of the activity and provides sample assessment form. (MKR)

The author describes a series of current economic ideas and situations which can be used in the mathematics classroom to illustrate the use of signed numbers, the coordinate system, univariate and multivariate functions, linear programing, and variation. (SD)

Describes the use of graph theory and game theory to deepen students' appreciation of Ferdinand Magellan's story and his magnificent contributions as an explorer. (MKR)

Using data about companies with which children have first-hand experience (such as McDonald's or Mattel Toys) piques interest in graphing activities. How the project is developed, with group and individual activities, is described. (MNS)

A restaurant menu is used to apply mathematics to real situations. A variety of mathematical problems, as well as applications to other content areas, is suggested. (JT)

The problem of controlling the grizzly bear population at Yellowstone is described. The results are presented in graphical form and discussed. A computer program is included. (MNS)

Presented are activities which use data from an instrument which combines speedometer, odometer, and clock readings on a circular graph. Applications of linear graphs using actual and simulated tachographs are discussed. Examples of student work are given. (CW)

In the activity described here students build mazes, then time fellow students as they "run" the mazes. They then graph the results to determine a learning curve. (SD)

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

The focus of these four activities is on gathering, using and interpreting data about bicycles as a basis for integrating mathematics. Measurement, ratios, and other relationships are explored through making graphs, finding bicycling speeds and a parent-involvement activity sheet. (CW)

Using the methods described, pattern representation of operations in modular systems can be developed. (SD)
