http://www.mathdl.org/mathDL/5/
Math DL, The Mathematical Association of America's
Mathematical Sciences Digital Library, recently
introduced OSSLETS as their newest collection. The first
three Open Source, Sharable Mathlets (OSSLETS) use
Macromedia Shockwave and Macromedia Flash:
 multiParameter Animation  create live graphs and
animations of one or more functions that depend on
several parameters
 linearTransformation  explore visually the effects
of a linear transformation of the plane given by a
matrix equation y = Ax
 PlanarGraphs  study planarity for graphs
Visual Math Learning

Wayne Allen Bateman describes his Visual Math Learning site
as "a free educational web site featuring an interactive
tutorial for teaching elementary mathematics and basic
arithmetic. It is an instructional aid for parents,
teachers, and educators of primary, elementary, and middle
school students. The lessons include games, puzzles,
animations, and virtual manipulatives that emphasize learning
concepts by visualization."
Links from Bateman's main page include narrated lessons and
interactive games that require the Flash plugin:

Mechanical Drawing  Sanders

Cathi Sanders has written web pages detailing the Mechanical
Drawing course that she developed for Punahou School. Her
description is:
"Mechanical Drawing is a oneyear, onecredit course at
Punahou School, in Honolulu, Hawaii. The purpose of this
course is to introduce students to technical drawing, as used
in the professions of Graphic Design, Architecture,
Engineering and related fields.
"In this class, students will learn how to draw in 2 and
3dimensions using pencil and paper and using computer
software. In learning different drawing techniques, students
will do a variety of creative projects such as designing a
logo for a business and a poster to advertise an event
(Graphic Design), designing a simple invention and a package
(Industrial Design, Product and Package Design) and designing
their 'dream home' (Architecture)."
Sanders recently retired from teaching at Punahou School,
Honolulu, Hawaii.
