Provides practical applications of elementary coordinate geometry while discussing how mathematics is used to assess the security of systems. (ASK)

Describes some general techniques for making collapsible models, including spiral models, for all the Platonic solids except the cube. Discusses the nature of the dissections of the faces necessary for the construction of the spiral cube. (ASK)

Presents an activity using quilts for many mathematical investigations. Benefits arising from the use of quilts include being useful, visually appealing, steeped in history, and an integral part of many cultures. (ASK)

Integrates different geometries and blends several topics that have important applications in both higher mathematics and other disciplines. Aims to make these topics more attractive and understandable to high school students in a way that reinforces logical thinking with visual understanding obtained through computer usage. Contains 28…

Presents an activity on soap-bubble geometry using a guessing contest, explanations, and demonstrations that allow students to mesh observation and mathematical reasoning to discover that mathematics is much more than just number crunching. (ASK)

Presents Cevian geometry problems (involving a segment that joins a triangle's vertex to a non-vertex point on opposite side) that illustrate how to implement methods for developing flexible strategies of problem solving, finding multiple representations, and making connections to other areas of mathematics and the real world. (ASK)

Presents a student description of the Cape of Good Hope project in which pairs of students designed capes and cloaks out of garbage bags for a fashion show. (ASK)

The World's Largest Math Event 6 (WLME 6) is the National Council of Teachers of Mathematics' (NCTM) celebration of mathematics and mathematics education and is the highlight of Mathematics Education Month. This year's event, slated for April 28, 2000, features the theme "Animals as Our Companions". This theme encourages students to…

Presents four related problems that provide examples of ways to include justifications of interesting mathematics in courses taught prior to a geometry course. (ASK)

Describes an activity on fractal geometry in which students built a 19-foot-tall Sierpinski pyramid in the Minneapolis Convention Center in conjunction with the National Council of Teachers of Mathematics' (NCTM) 75th Annual Meeting in April, 1997. Contains 13 references. (ASK)

Features a brief description of fractals and their characteristics, some example activities, and an argument for including fractals in the mathematics curriculum. (ASK)

Considers teaching strategies to help children overcome misconceptions and difficulties with the mathematical concept of angles. (ASK)

Presents detailed information about the Cape of Good Hope project in which pairs of students designed capes and cloaks out of the garbage bags for a fashion show. Also describes student objectives, unit goals, group activities, products required, and the final show and presentation. (ASK)

Describes a discovery-based geometry unit that keeps students actively involved in their learning. Highlights how geometry surrounds students every day. (ASK)

Presents a class project for creating a time line depicting the history of geometry that includes writing short biographies of mathematicians and summarizing geometric ideas to form an historical perspective. (ASK)
