operations, geometry and measurement, functions and algebra,
and probability and statistics. Java applets are provided
for these and other activities:
- Venn diagrams
- Lock arithmetic
- Pythagorean explorer
- Tessellate!
- Vertical line test
- Boxplot
- Monty Hall
- Stock Exchange
- Buffon's Needle
http://www.shodor.org/interactivate/activities/
Discussions model mentor-student dialogues, providing ideas
that introduce or explain a concept, and pointing out common
student misconceptions. See also the site dictionary of
important mathematical terms used in the lessons:

The materials are designed to be easily adaptable to NCTM
Standards-based middle-school mathematics texts, and lessons
are linked to chapter headings of four representative texts:
Interactive Math (Glencoe, a division of McGraw-Hill);
Math Thematics (McDougal Littell); Mathematics in Action
(Macmillan/McGraw-Hill); and Middle Grade Mathematics
(Prentice Hall). The project is funded in part through the
Presidential Technology Initiative.
