JIM WILSON  MATH EDUCATION IN ACTION ON THE WEB
http://jwilson.coe.uga.edu/
Professor Jim Wilson of the Dept. of Mathematics Education, Univ. of Georgia, uses the Web to explore his interests in mathematics problemsolving processes, curriculum, teacher education, use of technology in mathematics teaching and learning, and the evaluation of math learning. Materials include course syllabi, essay ideas and sample essays, and instructional units.
Courses on Computers & Algorithms and Problem Solving in Mathematics Education include libraries of investigations created using The Geometer's Sketchpad. Graphically illustrated math papers explore such topics as:  Ratio of areas of two squares  Capturing Area and A Solution  Curve Building; Orthotravels  Tangents Problem  Explorations with Heron's Formula  Triangle Ratios Problem (Ceva's Theorem)  Witch of Agnesi
A small library of GSP lessons with hints on construction is also available to download or view if your browser is configured to use Sketchpad as a helper application. The Forum's Instructions for setting this up can be found at

CRITICAL THINKING PUZZLES
http://forum.swarthmore.edu/k12/k12puzzles/critical.thinking/
"When we think critically we become better learners. We don't just accept facts, we explore them, uncovering connections and identifying the often hidden causeandeffect relationships."
The Math Forum is featuring a selection of brain teasers from Michael DiSpezio's new book, Critical Thinking Puzzles. The book offers a wide variety of old favorites and new challenges for problemsolvers of any age.
Five puzzles are now available, with solutions:
 Pyramid Passage  Spare My Brain  Putting It Together  Fractured Farmland  Kitchen Cups

FROM THE EMAILBAG
I'm having trouble getting my homework done  are there homework sites for maths and social studies?
Hi there. Rather than send you a long list of sites, let me show you a few places you can look on the Web.
The first is right here at the Math Forum. We have a large database of links to math and education resources, so by using our searcher you may find just what you need. Start from our Internet Resource Collection:
http://forum.swarthmore.edu/~steve
Try the searching and browsing options  you may want to choose the QUICK SEARCH and use words such as "homework" (just the word, not the quotes) or the COMPLEX SEARCH to specify the grade level, math topic, and/or type of resource you're looking for. (If you have trouble deciding which searcher to use, read Choosing the Right Searcher.)
Here's an outside site to get you started. It's by student B.J. Pinchbeck (with a little help from his dad), and it's a great collection of over 340 sites on the Internet designed to help you with your homework.
