3-D Drawing & Geometry | Just For Kids: Math | On-line Interviews

           3-D DRAWING AND GEOMETRY - Cathi 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:

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.

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.

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. For how to participate, see:
