Math and language skills meet at a recipe-menu-measurement food information station. (Editor)

A series of problems concerning a geoboard with "holes" is suggested. (SD)

A discussion of early Egyptian hieroglyphic numeration and calculation is presented. (SD)

Elucidated is the relationship among three threads of mathematical investigations: Kirkman's schoolgirl problems, finite geometries, and Euler's n-square officer problems. (JP)

Twenty-four games to be played with a hand-held calculator are described. Information includes the number of players, the approximate time required, the skills involved, the chance factor, and the game sequence. (NR)

This book contains a collection of papers on the teaching and learning of mathematics. The work of A. G. Sillito, a renowned Scottish mathematics educator, is the theme for these papers. The first three papers emphasize Sillito's influence in Scottish schools. A wide variety of mathematical ideas are discussed in the papers and include such topics…

Graphs of exotic functions which can be defined using algebraic operations are discussed. (SD)

Estimating the weight of large pumpkins before harvest presents an opportunity for applying several diverse mathematical topics. A model that allows an estimation by easy tape measurement is derived. (MP)

Modern sophisticated computers are shown to multiply the same way the ancient Egyptians did more than 4000 years ago--by doubling and adding. (MN)

The author states and proves a relationship between the standard deviation and the range of any distribution. (MN)

A sequence of ellipses and a sequence of hyperbolas, both graphically approaching some parabola, are expressed algebraically and then shown to approach the parabola. (MN)

The problems presented at the U.S. Sixth Mathematical Olympiad as well as how the Olympiad selects, trains, and encourages future mathematicians is described. (JT)

Characteristics of the number seven, which relate to many different areas of mathematics, are discussed. (JT)

Several examples through which the Klein 4-group can be introduced are offered. (SD)

Identifies certain principles of mathematics-like thought participated in by the carvers of the petroglyphs: (1) iteration; (2) recursion; (3) similitude; (4) tiling; and (5) symmetry. Provides illustrations and verbal descriptions of each process and concludes with four suggested classroom activities to help students appreciate the talents of the…
