Presented and discussed is a program for a programable calculator that predicts the altitude achieveable by a model rocket. (MP)

An algebra test was constructed within a Piagetian framework. Results of a selection of the test items are given and discussed. (MP)

This discussion of the mathematics portion of the examination includes topics covered, test development, and sample questions. (MP)

Techniques that can be used in solving various mathematical problems are illustrated by an optimization problem and the accompanying model and solution. (MP)

This survey reports data showing that mathematics courses generally use a modern approach but that there appears to be a slightly increased preference for traditional mathematics. (MP)

Difficulties encountered when drawing the graphs of linear equations are discussed. Programs are developed to overcome these and worksheets are given for further practice. (MP)

Allowing students to discover a winning strategy for this game is suggested as a way to introduce modular arithmetic. (MP)

One hundred and seven students of 365,000 students given the annual High School Mathematics Examination took part in the sixth U.S.A. Mathematical Olympiad. The top eight scores are listed along with comparative Exam and Olympiad scores for the group and individual problem scores. The problems proposed on the U.S.A. Olympiad on an International…

An account of student efforts to solve the problem of finding the equations for a pair of parabolas that intersect in exactly three points is given. The deceptively difficult problem leads to the rational root theorem and eventually to computer programs for locating roots and for approximating irrational roots. (MN)

A method for finding the area of a circle is described which involves finding points on the circle with the aid of a calculator and then applying the formula for the area of a polygon. (MN)

The authors analyze student work in solving linear equations, categorize and discuss typical errors, and present resulting implications on instruction. (MN)

Several geometric and trigonometric proofs are discussed. These proofs were selected from a larger group because of their instructional value promoting enrichment or generalization. (SD)

Activities growing out of a study of Euler's formula are described. (SD)

The action in a British sporting event (bumping races) was used to motivate a simple method of computing the correlation between starting and finishing positions. The method is generalized to other situations. (SD)

Eight geometric construction problems with some unusual constraints are presented and then solved using only an unmarked straightedge and a compass. (JT)
