Peer reviewedBoltyansky, Vladimir – Quantum, 1992
Presents an allegory to illustrate the problem of testing an axiomatic system. A fictitious discussion begins by examining an axiomatic system underlying the intercom system of an association. The discussion continues to examine an unusual model of Euclidean geometry and a model of the noneuclidean geometry discovered by Lobachevsky. (MDH)

Peer reviewedRickey, V. Frederick – Mathematics Magazine, 1992
Discusses aspects of Christopher Columbus' decision to sail west in order to reach Asia. Includes discussions concerning the shape and size of the earth as determined up to Columbus' time and conclusions he made during the journey based on his calculations. (MDH)
Descriptors: Astronomy, Earth Science, Geography, Higher Education
Peer reviewedDubrovsky, Vladimir – Quantum, 1992
Discusses flexible polyhedrons, called flexors, that can be bent so that the faces stay rigid while the angles between them seem to change. Presents models representing flexors and directions on how examples can be constructed. (MDH)

Peer reviewedBogdanov, Constantine – Quantum, 1992
Discusses the mathematical model presented by Vito Volterra to describe the dynamics of population density. Discusses the predator prey relationship, presents an computer simulated model from marine life involving sharks and mackerels, and discusses ecological chaos. (MDH)

Peer reviewedShubin, Mikhail – Quantum, 1992
Presents a proof of Euler's Theorem on polyhedra by relating the theorem to the field of modern topology, specifically to the topology of relief maps. An analogous theorem involving the features of mountain summits, basins, and passes on a terrain is proved and related to the faces, vertices, and edges on a convex polyhedron. (MDH)

Peer reviewedWoodwars, Ernest; Brown, Rebecca – Arithmetic Teacher, 1994
Presents three hands-on, discovery geometry lessons based on the use of special pieces called Polydrons by a fifth-grade class to build and investigate special properties of polyhedra and to stimulate students to think geometrically. Includes reproducible student worksheets. (MKR)
Descriptors: Algebra, Discovery Learning, Elementary Education, Elementary School Mathematics
Peer reviewedBennett, Albert B., Jr.; Nelson, L. Ted – Mathematics Teaching in the Middle School, 1994
Presents an alternative method to teaching percent problems which uses a 10x10 grid to help students visualize percents. Offers a means of representing information and suggests different approaches for finding solutions. Includes reproducible student worksheet. (MKR)

National Council of Teachers of Mathematics, Inc., Reston, VA. – 1988
These materials on geometric probability are the first unit in a course being developed by the Mathematics Department at the North Carolina School of Science and Mathematics. This course is designed to prepare high school students who have completed Algebra 2 for the variety of math courses they will encounter in college. Assuming only a knowledge…
