The problem of finding the maximum number of right angles a polygon can have, given the number of sides, is discussed in detail. (MP)

An experiment is described which started with exploratory interviews, evolved to design and administration of diagnostic tests, and led to the preparation and use of calculator-enriched teaching materials. (MP)

Several computer-oriented lessons designed to explore and exploit the problem-solving capabilities of currently available, inexpensive systems are presented. The programing language BASIC is featured. (MP)

Learning activities based on a geometrical puzzle that consists of rearranging triangles and trapezoids are used to teach concepts involving area. (MP)

The results of exercises related to fractions on the National Assessment of Educational Progress (NAEP) for 9- and 13-year-olds are reported. This discussion is followed by suggestions on ways to help students be more successful when adding fractions. (MP)

A method of study which is inefficient but used by large numbers of students taking courses in mathematics is described. The wide relevance of the problem, for subjects other than mathematics, is also examined. (MP)

A brief outline of instruction for one unit of informal geometry is covered. The problem solving unit described involves work with picture frames and includes many mathematical concepts. (MP)

Aspects of the instruction of trigonometry in secondary school mathematics are reviewed. Portions of this document cover basic introductions, a student-developed theorem, the cosine rule, inverse functions, and a sample outdoor activity. (MP)

A collection of calculator activities designed for lower level mathematics students is presented. The calculator is viewed as a tool to provide unmotivated or unskilled pupils with the opportunity to explore mathematical ideas successfully. (MP)

A collection of learning activities viewed as challenging and suitable for junior high students in grades 7 and 8 are presented. The questions are designed to suggest other situations and encourage mathematically gifted pupils to develop, practice, and refine analytical thinking skills. (MP)

Several examples of games and enrichment activities designed to be used with calculators in an elementary school setting are presented. Some possible difficulties students may encounter while carrying out the activities are reviewed. (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)

It is argued that a young child's perceptual skills form the basis for all future conceptual and mathematical learning. An experiment supports the argument. (MP)

Describes the Six Through Eight Mathematics (STEM) middle school mathematics curriculum project. Emphasizes that the use of thematic modules promotes students' development and application of mathematical concepts in broad contextual situations. Presents an assessment criteria for teachers and focuses on the use of open questions and their role in…

The principal of a grade 3-5 intermediate school explains how he gained teacher acceptance of a new mathematics curriculum and instructional methods meeting National Council of Teachers of Mathematics standards. To raise students' mastery scores, the principal worked with teachers from each grade to reexamine present practices, develop and test…
