```      MATH TOOLS NEWSLETTER - DECEMBER 6, 2003 - No. 9

Last April when we first unveiled Math Tools, resources
from Shodor's Project Interactivate and Utah State's
National Library of Virtual Manipulatives populated the
first course that we opened, Math 7. Recently the
Project Interactivate resources have been re-cataloged
so that they are aligned, taking all of the courses into
consideration. Next month the re-cataloging of Utah
State's resources will be complete as well.

Over 2300 users are registered Math Tools community
members and over 2000 items are in the catalog. We
appreciate your interest and participation in Math Tools
as we develop this new digital library.

***FEATURED TOOL
Rabbits and Wolves Applet
Shodor: Project Interactivate
http://mathforum.org/mathtools/tool.html?id=379
This simulation of population dynamics contains "rabbits,"
"wolves," and "grass." It keeps track of statistics over
time, producing a graph showing cause and effect of the
increasing and decreasing populations. The many parameters
of the simulation allow you to vary it to discover how your
changes affect the overall system over time.

***FEATURED LESSON
Shodor: Project Interactivate
http://mathforum.org/mathtools/lesson.html?id=310
This lesson is designed to introduce students to graphing
functions and to reading simple functions from graphs. Many
of the examples are motivated by a situation described by
the graph.

***TOOLS DISCUSSION
Math Tools Discussions on Problems of the Week Using
Java Applet Technology
http://mathforum.org/escot/boone.html
A discussion started on Friday, November 21, between Susan
Boone, her students, and members of the Math Forum staff.
We invite you to try the problems and contribute to the
discussion.

***DEVELOPERS AREA DISCUSSION
Jill Britton requested that someone update the Magic Square
Java Applet and George Reese has asked a programmer at MSTE
to work on an improved applet. Watch this discussion thread
for updates on the progress of this improvement.

***RESEARCH AREA DISCUSSION
Participation has begun on the action research project that
George Reese presented in the Research Area last month. If you
are interested in participating, feel free to join in the
discussion.
