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)

Presents an activity in which students learn how to label graphs in order to make them meaningful. (ASK)

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

Procedures to help algebra students solve problems more efficiently are discussed, using linear programing graphs. (MNS)

Four different types of problems from graph theory are presented and discussed. (MK)

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)

Presents a real-life example of mathematical modeling in which a medical company asks for help in solving a warehouse-inventory problem. Uses charts, graphs, and computers. (MKR)

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)

Graphs are viewed as extremely useful tools in communication, which enable readers to see at a glance facts that might take several paragraphs to describe adequately. An ability to read graphs critically is seen to be an important objective for any elementary curriculum, and ways to introduce them are presented. (Author/MP)

It has been found that students gain much greater insight into routine calculations with business formulas when such work is viewed in the light of graphing concepts. Ten problems are presented that illustrate how three specific objectives in a unit on graphing in a business mathematics course have been met. (MP)

Presents activities designed to help students bridge the gap between the graphical representation of a function and a verbal description. Includes a number of nonstandard graphs and reproducible student worksheets. (MKR)

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)
