Activities involving the drawing of kites and figures related to kites are described. (SD)

Curve stitching activities can be used to motivate calculus students. The problem described here involves showing that a given envelope of a curve is parabolic. (SD)

The use of paper folding to study properties of geometric solids is discussed. (SD)

After stating that almost any topic could be generalized, the author was challenged to generalize the topic of polyominoes. His response is presented in this article. (SD)

Reluctant learners made plastic geometric shapes for use in classroom activities. (SD)

This simple example demonstrates the physical significance of similarity solutions and the utility of dimensional and asymptotic analysis of partial differential equations. A procedure to determine the existence of similarity solutions is proposed and subsequently applied to transient constant-flux heat transfer. Short-time expressions follow from…

Pupils' understanding of angle is investigated. Areas of difficulty and misconceptions are highlighted with a view to recommending improvements in the presentation of angle in primary school and remedial work to overcome problems in secondary school. The material opens with a historical and mathematical background and a brief review of research.…

This text provides a one-semester study of analytic geometry for secondary school students. It is designed for use at the 12th grade level. A deliberate effort was made to tie this text to previous SMSG texts; the usual language of sets, ordered pairs, number properties, etc. are included. This flavor is what distinguishes this book from others in…

This publication contains a sequence of lectures given to high school mathematics teachers by the author. Applications of mathematics emphasized are elementary algebra, geometry, and matrix algebra. Included are: (1) an introduction concerning teaching applications of mathematics; (2) Chapter 1: Mechanics for the High School Student; (3) Chapter…

Paper folding activities can illustrate transformations that are circular and finite under one set of conditions and become rectangular and infinite when conditions change. (SD)

This textbook is an essay on evidence and mathematical reasoning as applied in geometry. This volume also contains: (1) A Letter to Erasmus Darwin, M. D. on a New Method of Treating Pulmonary Consumption, and Some Other Diseases Hitherto Found Incurable; and (2) Letters From Dr. Withering, of Birmingham, Dr. Ewart, of Bath, Dr. Thornton, of…

The relationship of performance in mathematics to syntactical language factors obtained from speech samples was investigated with 95 senior high school geometry students. Statistical procedures included correlation analysis and stepwise regression. The findings indicated that certain syntactical measures indicating logical thought processes…
