Learning activities designed to help students gain experience in reading three types of maps and in using the results to solve multistep problems about average speed and cost per mile are presented. Worksheets suitable for reproduction are provided. (MP)

Three questions dealing with hypothesis testing are presented. Activities that can be best worked with calculators as tools are detailed and suggestions for extensions of these problems are given. (MP)

Seven activities designed to lead students to the idea that the ratio of the perimeter of a square and its diagonal is a fixed number for all squares are presented. The activities are groundwork for preparing students for the ratio between the circumference and diameter of a circle. (MP)

A method for approaching the value of pi using a transparent sheet of parallel lines is discussed. (MP)

Use of computerized testing to give frequent evaluations of student progress is explained. (MP)

Describes that little evaluation is conducted by most textbook publishers. Suggestions for ensuring the availability of quality mathematics textbooks are given. (MNS)

Involving students in generating and solving their own problems is proposed. A method for generating problems by using a number puzzle is presented. Ideas for using the "what if not" technique are also given. (MNS)

The advanced study program sponsored by the U.S. Naval Academy for the Anne Arundel Public Schools is described. Graphs, Games, and Puzzles and Strange Algebras are two of the courses presented. (MNS)

How physicians turn the data from tests and evaluations of patients into information useful for medical action is described. This is an important application of the distance formula. (MNS)

Included in this section are brief articles on making up a story to explain a graph, the inverse of a function of a single variable, and exotic horse-race wagering and combinatorics. (MNS)

A computer program is presented which simulates the classical probability machine, using Applesoft II high-resolution graphics. Many variables are left to the user's choosing. Suggestions for using the machine, understanding the problem, the mathematical model, and further program documentation are given. (MNS)

Factorials are discussed, with note of the enormous size on n! even for modest values of n. A recreational problem to determine the number of zeros at the end of numbers such as 10,000! is given, with a computer program. (MNS)

References to approximations of pi in the Bible and calculations of pi in the Egyptian Phind Papyrus are noted, followed by a finding of an eighteenth-century Polish rabbi about the exactness of the Biblical computation. (MNS)

Teachers can partially remedy misconceptions and anxiety about mathematics by incorporating a historical perspective into mathematics teaching. Numerous examples of how this can be done are presented, along with ideas illustrating the growth and evolution of mathematical ideas. (MNS)

A method used by the ancient Babylonians to solve quadratic equations is presented. Illustrations are included from one Babylonian tablet. (MNS)
