A mathematics problem is presented and solved which concerns determining the approximate speed of an automobile involved in an accident. Extensions of the problem are suggested. (DT)

This book is designed to help adults gain the range of math skills they need to succeed in life and work and on standardized tests including the GED. It is expected to help students overcome math anxiety, discover math as interesting and purposeful, and develop good number sense. Lessons are organized around four strands: (1) skill lessons…

Examples, exercises, and solutions involving compound growth are contributed that emphasize the areas of lending, borrowing, and investing. It is felt these areas present a wealth of opportunities for mathematical modeling, the development of algorithms, and practical applications, and can be fully explored throughout typical secondary…

The mathematical nature of the product barcode that now appears on many supermarket goods is discussed. Particular attention is given to the nature and formula of a "check digit" used to verify that product numbers are correctly scanned. Several possible student activities related to this code and others are suggested. (MP)

A discussion of the reasons for the new design of international standard typing paper (AY) with dimensions of 210 mm by 297 mm leads to a discussion of the ratio of the sides and geometric concepts involving similar rectangles. (MP)

An excursion in applied mathematics is detailed in a lesson deemed well-suited for the high school student or undergraduate. The problem focuses on an experimental missile guidance system simulated in the laboratory. (MP)

This report explains the mathematical origin of the Annual Percentage Rate (APR) approximation often used in elementary Business Mathematics courses. (MP)

Having pupils create their own mathematical-application word problems is promoted as a powerful teaching strategy. Teachers are encouraged to make creative pupil applications an integral component of day-to-day learning in mathematics. Research is cited that strongly favors the approach presented. (MP)

These exercises are designed to expose students to the nature and effects of inflation and consumption rates. Pupils are expected to see how long it takes for costs to increase to certain levels, and how quickly various growth rates can deplete a finite resource. Worksheets suitable for duplication are provided. (MP)

A class of seldom-seen real-world applications of high school mathematics is described. The problems considered are viewed as more substantial than ordinary word problems and thus are thought to require a greater commitment of time and energy. Suggestions for student extensions of the project are made. (MP)

Gardening is the theme for a series of worksheets that present a variety of problem-solving activities that emphasize the construction, use, and interpretation of diagrams, graphs, and tables. The material is designed for duplication for classroom use, and suggestions for ways of going further are provided with each activity. (MP)

The needs of mathematics teachers who wish to provide relevance in their lessons, and the need to infuse energy topics into all disciplines in the curriculum at all grade levels, are addressed. It is felt children could be adversely impacted by present energy practice, and education is essential. (MP)

An approach to the instruction of maxima and minima problems that works with tools of geometry and algebra is presented. The focus is on a classic pie-cutting problem, which is viewed as an interesting and instructive task that is an excellent application of transformation geometry. (MP)

The mathematics of an educational game commonly known as "Frogs" is analyzed to see different mathematical concepts imbedded in it. (MP)
