Some activities involving distances and diameters in the solar system are discussed. (MP)

Differing treatments of graphs in mathematics and science are discussed. A teaching sequence to develop contrasts between real and ideal data is suggested. (MP)

Relates the study of geometric forms to the chemical structures of organic compounds, discussing isomerism and the occurrence of regular solids in chemical phenomena. (CS)

Since many texts use an incorrect argument in obtaining the instantaneous velocity of a rotating body, a correct and concise derivation of this quantity for a rather general case is given. (Author/SK)

The author recommends establishing a student-run classroom or school business to teach about work and money and to motivate mathematics learning, as well as to raise money for student activities. He describes the toy store run by his students and suggests other types of suitable businesses. (SJL)

The development of a mathematics model to simulate small animal populations is described. Assumptions of the population model and options in the program are discussed. (MK)

This article describes the development of a unit for a team-taught middle school program integrating mathematics skills with map and globe skills such as distance, direction, scale, longitude, latitude, location, and climate. Some of the learning activities of the unit are outlined. (Author/SJL)

The computation, concept, and application subtests of the Stanford Achievement Tests (SAT) were administered to a student sample during grades 3, 5, and 7. The efficiency of earlier scores and Otis Lennon Mental Ability Test scores in predicting seventh-grade SAT math scores was examined and found to be weak. (SJL)

Details of a course on mathematical modeling for graduate teachers of mathematics are presented. The rationale, objectives, course content, assessment methods are discussed along with several illustrative examples and difficulties encountered in finding appropriate problems. (MP)

The formula used by the telephone company to determine long distance charges is presented and several sample problems are included. (MP)

A model of competition probabilities using past performances of competitors against common opponents is constructed. Application to predicting victories in athletic competitions is also reviewed. (MP)

The issue of how much emphasis balancing chemical equations should have in an introductory chemistry course is discussed. The current heavy emphasis on finishing such equations is viewed as misplaced. (MP)

Record-breaking snowfalls are the starting point of a presentation that delves into many aspects of probability and interesting and unusual aspects of viewing independent, random phenomena. (MP)

The use of solid cardboard geometric shapes as molds to make candles is presented as a possible mathematics enrichment activity. (MP)

Women tend to subscribe to a belief that they are less inclined than males to handle numbers, logic, or problem-solving tasks. Upward mobility in occupations is seen to be dependent on math. A list of math anxiety, math avoidance, and math reentry programs given around the country is provided. (MLW)
