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)

Teachers are encouraged to have pupils examine the symmetry of crystals when instruction is given on three-dimensional geometry and polyhedra. Crystals are noted to provide students with three-dimensional applications of transformational geometry, and the pupils also learn mineral identification. Suppliers of mineral models and specimens are…

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)

An approach to blending mathematics and art based on the development of student-made designs using some simply stated rules is detailed. Several examples are given along with suggestions for extensions of the activity. It is felt pupils will enjoy and be challenged by this blend of material. (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)

A series of situations is suggested incorporating hands-on activities involving concrete experiences with measurement. It is felt that the activities used to teach mathematics and science at the Middle School level need to be specifically suited for the young adolescent. Extensions are possible for in-depth investigations for more advanced…

A series of activities designed to teach time-telling is presented. Each activity is illustrated with very few examples, but it is noted that many other examples may need to be provided for students. It is hoped that this material will help instructors in teaching time-telling skills. (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)

The mathematics for a lunar shuttle landing simulation is discussed using equations, charts and tables. (MP)

Results of two national surveys indicate that sex differences in achievement on mathematical applications persist even when different levels of mathematics participation are controlled. (MP)
