PYTHAGORGRAMS - June Lester
http://thejuniverse.org/Mathdesign/widgets/Pythagoras/
June Lester has developed a simple tangram-type learning
widget, accompanied by nine questions, to help students
understand Pythagoras' theorem. Pythagorgrams require
a Flash 6 plug-in.
Lester, a mathematician at Simon Fraser University,
started the Math Design site in October 2002, with her
first article, "Math Design: the what and the why of it."
She describes the site as a home for her ideas and demo
experiments in designing onscreen mathematics, such as
Pythagorgrams, focusing particularly on its visual and
interactive aspects.

correct answer; answer correctly, and it runs an animation of
a basketball player shooting hoops. Each question is created
randomly with variability.
Topics include:
- Addition
- Subtraction
