Preservice elementary teachers were given the task of showing a special case of the Pythagorean theorem by paper cutting. In the process they developed approximations to the square root of two. (SD)

This paper describes the nature and use of a computer-assisted sequence of instruction in college-level mathematics. Units in differential and integral calculus and geometry are described. The authors claim that students acquire increased confidence in their knowledge and problem-solving ability. (SD)

This article was written in part to celebrate the anniversaries of landmark mathematical works by Newton and Descartes. It's other purpose is to dispel some myths about Sir Isaac Newton and to encourage readers to read Newton's works. (PK)

Presents a variety of mathematics activities for students to solve. Sections are included on geometrical dissection, prime numbers, trigonometry, and number concepts. (RH)

Presented are activities and references involving tangrams. Seven pieces are cut from a single square of paper; other shapes and objects are made from these pieces. (RH)

A theorem is given for a property of right triangles. From it, students can deduce significant relations. (MNS)

The role of sentential logic traditionally taught in high school geometry is challenged. A rationale for shifting that content to algebra and replacing it with inferential logic, which directly affects proof making, is given. (MNS)

Activities involving the drawing of pictures using coordinate geometry are described. One year a contest was held; another year, murals were drawn on walls. (MNS)

Following a brief introduction to the LOGO programing language, describes its use in a sixth-grade classroom. The situations described illustrate students' growth while the choice of the situations illustrates teachers' growth. (JN)

Discusses the place of descriptive geometry in schools problems of teaching technical graphics to young students. Instructional materials for teaching technical graphics, graphic programs, program development, and the value of school project work are considered. Sample computer-generated drawings are included. (JN)

Presents three activities in which students learn about and construct star polygons using the LOGO programing lanaguage. A list of suggested extension activities is included. (JN)

Four worksheets on geometry are given. Experiences in identifying and constructing described shapes, drawing congruent polygons, and visualizing the shapes needed to build hexagons are included. (MNS)

Uses of the historical approach to the teaching of mathematics throughout the last century are discussed. Examples from turn-of-the-century tests are provided, and the place of history in Mathematics teaching today is explored. (SD)

Extracts from booklets providing critical reviews of and recommendations related to textbooks of the Nuffield Mathematics Project are presented. (SD)

The cognitive range of 13 geometry teachers' questions was analyzed, and the extent to which these teachers asked questions at each of the four levels was analyzed. Findings showed significantly more comprehension questions than memory, application, or higher-level questions, and significantly more memory and application questions than…
