Describes how to construct a simple device that students can use to estimate how high their kites are flying, as well as the heights of other objects. (TW)

Discusses computer methods for finding roots of polynomials. The program provided finds rational roots and prints the roots as rational numbers. (PK)

Described are differences in the mathematical problem-solving performance of third-grade gifted and fifth-grade average students observed during an eight-week period. Results indicate that attitudes, motivation, and belief systems were important to performance. There were major differences in problem-solving behavior between boys and girls.…

Abstracts of seven selected papers from the 7th Annual Microcomputers in Education Conference are presented. Papers are included on microcomputer-based labs, teaching science with robots, microcomputer software, problem solving, computer integrated math activities, and computer assisted mathematics. (RH)

Discusses the status of the testing of computational estimation. Suggests ideas to promote needed immediate actions and examines issues related to effective assessment of computational estimation. (PK)

Suggests a series of ratio activities that make use of a computer to produce graphical collections of objects in a grid with variable dimensions. Extends content to the areas of proportions, statistics, probability, programming, and problem solving. (PK)

Argues that reasons for teaching geometry before second-year algebra include higher student achievement and attitude and better abstract thinking. (PK)

Describes and gives patterns for polyhedra other than the Platonic and Archimedean solids. The focus is on the deltahedra, but pyramids, prisms, and antiprisms are discussed first to help describe the deltahedra. (PK)

Presents examples of visual representations helpful in understanding number relationships and the algebraic statements of these relationships. Suggests that these representations can be used by teachers to aid students in discovering number relationships and in acquiring meaning for given mathematical statements. (PK)

Recounts a classroom experience which investigated whether any integral solutions for the law of cosines would be analogous to "Pythagorean triples." Several interesting relationships were discovered. (PK)

Describes a three-week summer course for academically talented high school students which explored the integers and some classical topics from number theory. (PK)

Reviews for three software packages are given. These include "Equation Math," consisting of three programs for exploring graphs of the equations; "Recycling Logic," instructing students in the basics of reasoning; and "Turboplot-3D," intended for university-level mathematics, physics, engineering, and computer courses. (PK)

Delineates and describes four types of questions which may help teachers learn more about student understanding, namely, silent questions, oral questions, written questions, and students' questions. (PK)

Suggests that the mathematics curriculum for young children can grow from children's literature. Examples given encourage children to use a variety of thinking skills including classifying, forming hypotheses, selecting strategies, and creating problems. (PK)

Presents a variety of examples through which kindergarten and primary grade children can engage in significant problem solving. The suggested activities use materials in a problem solving context to permit children to experiment, to create, and to make measurements. (PK)
