Presents attributes of different types of software including Logo, geometric packages, graphical packages, and spreadsheets, each of which offers different opportunities for learning. Investigates the different ways in which the software allows for performing the given task so as to make the mathematics of the task explicit to users. (KHR)

Explores the mathematics of flight. Also contains a student worksheet. (YDS)

Presents a mathematics game appropriate for middle school or high school students that aids in the teaching and understanding of closure properties. (Author/NB)

Describes how mathematical understanding grows and develops while children play with the mathematical ideas they see emerging as they hear and talk about the story "Selina and the Bear Paw Quilt". (Author/NB)

Presents a case study of young children measuring on the playground to illustrate the development of understanding of units of measurement and the importance of teachers capitalizing on the informal mathematical situations that arise naturally in children's conversations. (Author/NB)

Geometric and algebraic solutions to problems involving reflections of balls on a pool table are presented. The question of whether the ball must eventually enter a pocket is explored. A determination of the number of reflections is discussed. (CW)

Introduces a statistics curriculum emphasizing an instructional sequence of practical, real data, discussion, and model/theory instead of theory, example, and practice. Provides one example and describes the teaching methods of the curriculum. (YP)

Possible ways of mechanization for counting using a binary system are discussed. Shows a binary representation of the numbers and geometric models having eight triples of lamps. Provides three problem sets. (YP)

Compares experiences in two calculus courses for non-science majors: a traditional business calculus course and a course using materials from the Calculus Consortium based at Harvard. The latter program is recommended. (MKR)

Tensile and compressive forces in planar trusses can be analyzed using either the method of sections or the method of joints. This article summarizes and extends a project accomplished by a high school student using the method of joints and graphing calculators, spreadsheets, and matrix-manipulation software. (MKR)

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)

Presents an activity that enables students to answer for themselves the question of how fast a body must travel before the nonrelativistic expression must be replaced with the correct relativistic expression by deciding on the accuracy required in describing the kinetic energy of a body. (ZWH)

In Putnam County, Ohio, an integrated curriculum applies science and math through enhancements to hands-on laboratory components and linkages with local manufacturers. The high school students learn to apply theories to real-world situations, develop teamwork skills and computer literacy, and learn about local employers. (SK)

Recommends using probability paper, also called normal probability and arithmetic probability paper, for solving probability problems. Provides six examples. (MVL)
