In this instructional guide, a third-level, two-semester mathematics course specifically for the student who plans a career in a vocational field is presented. The course is designed to meet the needs of students with varying mathematical backgrounds and to teach the mathematical skills required by various technical areas. In this practical…

A problem solving approach to the teaching of the Pythagorean Theorem is described. (SD)

A game, similar to bingo is described, in which students match names, symbols, and figures. (SD)

These materials, used in a self-paced course in engineering descriptive geometry for freshman and sophomore college-level students, cover three modules: basic spatial relationships; intersections, parallelism, and perpendicularity; and graphic analysis and development. Each module contains five instructional units. Each unit includes a rationale,…

The "geometry of distortion" and some prestidigitation show kids that lines, surfaces, and planes are not always what they seem. (Editor)

Provides domino geometry problems, problems with arithmetic progressions, and magic pentagram sums. (JM)

Presents a collection of problems focusing on: (1) squares in arithmetic and number theory; (2) squares in geometry; (3) topics blending arithmetic and geometric aspects of squares; and (4) squares and Logo. A sample student worksheet (with answers) is included. (JN)

Explorations of Pascal's triangle through computer programming are described. Programming offers different methods and techniques that enrich the topic. (MNS)

Three ideas are explored: (1) an improvement of the SSA congruence theorem for trigonometry; (2) a discussion of the failure of SSA in spherical geometry; and (3) an extension of SSA to spherical geometry and hyperbolic geometry. (MNS)

Presented are worksheets designed to provide experience in identifying, discriminating, and drawing geometric shapes; introduce area approximation or irregularly shaped figures; provide practice in estimating and determining areas of irregular plane regions; and provide experiences in making tile designs. (MP)

Activities used with gifted elementary students as part of a Title IV project are presented. The project was viewed to sharpen the analytical and investigative skills of participants, with both deductive and inductive critical thinking modes improved. It is felt everyone can reap tremendous benefits working with Soma. (MP)

Spatial concepts are important to the development of many skills, including reasoning and problem solving. Here are guidelines for making geometry learning more effective for elementary-grade students. (Editor)

Detailed instruction and worksheets are given for an activity designed to develop and improve geometric perception through the use of polyhedron models. (MP)

Diverse activities using large blocks are described. By building and comparing configurations children can be led from concepts like long and high to concept of ratio. Games and activities to help build other concepts are also described. (SD)

A series of lessons in which the concept of symmetry is informally developed is described. Rotational and reflection symmetries are examined. Pictures and sample worksheets illustrate the article. (SD)
