3 August 1998 Vol. 3, No. 31 THE MATH FORUM INTERNET NEWS 3-D Drawing & Geometry | Just For Kids: Math | On-line Interviews 3-D DRAWING AND GEOMETRY - Cathi Sanders http://mathforum.org/workshops/sum98/participants/sanders/ A geometry Web unit that illustrates different types of 3-D drawing through posters, paintings, and architecture. Students learn to create 3-D displays using geometric objects (e.g. prisms, cylinders, pyramids, and cones) drawn so that they appear to be three-dimensional. Cathi Sanders includes links to pages such as the Castles on the Web archive and the National Gallery, and lists of architectural sites, as well as a Java applet for playing with perspective: http://mathforum.org/workshops/sum98/participants/sanders/TryPersp.gsp.html Types of 3-D drawings featured include isometric, oblique, and perspective. There are figures drawn on grids to view, and grids that can be printed out for creating your own drawings. A final drawing project is outlined, student submissions are invited, and careers in 3-D drawing that use these techniques, from architecture to movies, are also illustrated. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- JUST FOR KIDS: MATH - Harcourt Brace http://www.hbschool.com/harcourtpages/justforkids/math/math.html Java and Shockwave activities for individual or cooperative group work, sorted by grade level for grades K through 8. "Teaching and Learning Resources" are provided for parents and teachers at the end of each grade-level list of activities, and the site also features a math glossary with examples for each term, many of them animated. http://www.hbschool.com/glossary/math/ Just For Kids: Math is hosted by the Harcourt Brace School Publishers' LEARNING SITE, which offers other parent and teacher resources and further topics (art, social studies, reading/language arts, health, science, etc.) in the Just For Kids section. http://www.hbschool.com/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- NETSURFING: ON-LINE INTERVIEWS WITH MATHEMATICIANS by Antreas P. Hatzipolakis http://mathforum.org/epigone/math-history-list/bahsywimp Hatzipolakis shares his findings with the math-history discussion group. There are links to interviews with Richard Taylor, John Conway, Vladimir Arnol'd, Shiing Shen Chern, Neil Sloane, Arthur Jaffe, Fred Wan, Ennio De Giorgi, and Bartel Leendert van der Waerden. Hatzipolakis then asks: "Quiz: Which is the ordering rule in the above listing?" The math-history-list is an unmoderated group dealing with the history of mathematics. It includes: announcements of meetings, new books, and articles; discussion of the teaching of the history of math; and questions that you would like answered.
