 March Workshops (31 March 2003)
 Radnor School District March 28, 2003: Annie Fetter, Shelly Berman, and Suzanne Alejandre worked with middle school and high school teachers to use The Geometer's Sketchpad as a tool to support mathematics instruction. The workshop was held at Radnor High School in Radnor, PA.
 Elizabeth School District March 25, 2003: Shelly Berman, Steve Rizberg, and Suzanne Alejandre worked with middle school teachers to use Math Forum resources to support middle school mathematics instruction. The workshop was held at Cleveland Middle School in Elizabeth, NJ.
 Notre Dame High School, March 14, 2003: Annie Fetter presented Math Forum @ Drexel: A Portal to Mathematics on the Internet to the math teachers at Notre Dame High School in Lawrenceville, New Jersey. The goal of the workshop was to familiarize the teachers with the different resources available that might help them incorporate the web into their classrooms and use it to augment their own professional development.
 PCTM, March 14, 2003: Suzanne Alejandre presented Making the Most of Math Forum Resources to participants at the Pennsylvania Council of Teachers of Mathematics 52nd Annual Meeting at Split Rock Lodge, Lake Harmony, Pennsylvania.
 PCTM, March 14, 2003: Varnelle Moore presented Primary Mathematics Activities to participants at the Pennsylvania Council of Teachers of Mathematics 52nd Annual Meeting at Split Rock Lodge, Lake Harmony, Pennsylvania. Varnelle demonstrated a selection of lessons from her units that use manipulatives, technology, paperpencil activities, and literature to teach mathematics to primary level students.
 Math Tools: Roundtable Discussions (20 March 2003)
 The Math Forum's new Math Tools project, is holding virtual roundtables to discuss
 what is good software for math education?
 how can we make things better?
Everyone is invited to participate in these discussions.
They are laying the groundwork for some of our future directions.
 Math Tools: Building a Community (7 March 2003)
 The Math Forum invites you to explore these questions with Math Tools, our new library for mathematics software. With so much math software already available, how do you find just the right tool? How do you figure out which technology really benefits your students?
See our Preview site to check out the evolving vision. We have extended the collection of applets already in the Forum's Library by collaborating with the Shodor Education Foundation, which has contributed applets from Project Interactivate, and Utah State University, which has contributed applets from the National Library of Virtual Manipulatives. For this preview of the site, we invite youto get a sense of Math Tools by browsing the first area that we've developed, which are tools intended for seventh gradelevel math.
To build a more connected community of mathematics teachers, researchers, and curriculum and software developers, we invite you to visit the Math Tools Research Area. Each month, moderator George Reese will post a brief summary of a publication in educational research and pose a few questions for discussion.

 Growth Creature Lab (7 February 2003)
 This is a lab developed by Mike Riedy at Prospect High School in Illinois, involving the growth of creatures. It ties their growth into the Fundamental Theorem of Similarity and extends into logistic growth. The lab shows students how to collect data from the growing alligators and how that data applies to geometry.
 2001 Report: Mathematics Education Around the World: Bridging Policy and Practice (6 February 2003)
 This report is the product of an international seminar on mathematics education held at the IAS/Park City Mathematics Institute on 1923 July 2001 at Park City, Utah, under the auspices of the Institute for Advanced Study, Princeton, New Jersey.
 10 Lessons in Fractals, Complex Patterns, and Chaos (6 February 2003)
 These lessons are an outgrowth of Jon Lee's involvement with the WrightConnection program held at WrightPatterson Air Force Base near Dayton, Ohio, during 19951999. The eight week summer program was designed to infuse the excitement of math and science into the classroom teaching of middle/high school math and science teachers. They participated in the realworld applications of math and science in an Air Force research laboratory.

 Inquisitive Problems (9 January 2003)
 B. S. Rangaswamy, a mechanical engineer from Bangalore, India has contributed two inquisitive problems on numerals to the college level area of the Teacher Exchange.
 New Dr. Math FAQ (7 January 2003)
 Divisibility Tests to 50 and Beyond
 Stephen D. T. Froggatt, Oaks Park High School, Ilford, Essex, UK, explains how the idea of deleting the last digit and adding or subtracting a multiple of the digit from the remaining number can be generalized to test for divisibility by prime numbers up to 50 and beyond. For more information on divisibility rules see also Divisibility Rules.
 Mr. Brandenburg's List of Recommended Books on Math and Science (1 January 2003)
 From others' recommendations and from his own reading as well, Guy Brandenburg has now compiled a list of over 140 math and sciencerelated books, mostly recent, for his geometry students to choose from, read, and do a report on. His new list, also available for download as a MS Word document, text file or PDF file, is organized by topic.
 2003 Mathematics Game  Judy Ann Brown (1 January 2003)
 A puzzle for students in grades 312 with a general knowledge of mathematics. Use the digits in the year 2003 and the operations +, , x, /, sqrt (square root), ^ (raise to a power), and ! (factorial), along with grouping symbols, to write expressions for the counting numbers 1 through 100. This year we will also allow the use of decimal points and doubledigit numbers.
