A Reuleaux triangle is an example of a curve of constant width; the distance between parallel tangents is the same no matter which direction is used. A consideration of a particular set of Reuleaux triangles is offered which leads to a good example of problem-solving in geometry. (JN)

Presents an activity for students in grades 7-10 (with ready-to-copy worksheets and overhead projector transparency masters) designed to develop the problem-solving skills of making and reading an organized list and searching for a pattern, and to provide practice in using the general heuristics of the problem-solving process. (JN)

The focus is on how line graphs can be used to approximate solutions to rate problems and to suggest equations that offer exact algebraic solutions to the problem. Four problems requiring progressively greater graphing sophistication are presented plus four exercises. (MNS)

The goals and history of the Mathematical Olympiads for Elementary Schools are described. Teams, levels, and gender are discussed, as well as teacher training, administration, scoring, and awards. Sample problems are included. (MNS)

The key to the success of decision support systems will be the way that institutional researchers integrate the variety of specific and personal systems into a viable and coordinated institutionwide system. (Author/MLW)

Portions of the Cockcroft Report which seem confusing are discussed. The connections among problems, applications, and investigations are considered in sections on being a mathematician; open is in the mind; assumptions, rules and patterns; and learning not to be anxious. (MNS)

Several examples of problems involving measurement that occur in the life of a contractor are presented, along with solutions. Several sample measuring activities for students are included, with comments. (MNS)

This handbook presents a collection of over 35 experiential and adventure-based activities using only a single item of equipment--a 15-foot long section of 1-inch tubular climbing webbing, called a raccoon circle. Some of the activities are quiet, some are loud, and they range from low to high challenge levels. Different-sized groups can be…

This guide presents games and activities on integrated pest management (IPM) for home targeting grades 1-7. The activities and games use a problem-solving approach based on pest knowledge to develop an understanding of pest management. Three cases are presented: (1) "Inspection is the Key to IPM Success" includes two…

This book offers teachers a toolbox for discovering the innate strengths and talents and the unique learning styles of each student. Drawing from Howard Gardner's work on multiple intelligences, the book offers more than a dozen activities specifically tailored to each of the eight multiple intelligences: verbal/linguistic, mathematical/logical,…

This book provides K-12 teachers with a series of lessons that promote the development of students' analytical, creative, and practical thinking skills. It is based on the theory of successful intelligence, which suggests that successful people use all three skills to achieve success. The book supplies educators with theories, techniques, lessons,…

The tree house detectives go galactic with their latest project by traveling to Mars and also seeing how the Moon affects the Earth. They visit the largest radio telescope in the world and help look for intelligent life in the universe. The tree house detectives prepare for an out-of-this-world vacation as they explore the future of space travel.…

A diffusion simulation is described in which the dispersion of potato beetles in a given problem is traced on hexagonal grids. (MNS)

The author reviews approaches involved with acceleration for gifted students: process learning (training students to think in creative ways); individualized education (including approaches that encourage students' participation in determining content and rate); and curriculum, program, and special projects.
