FOUNDATIONS OF MATHEMATICS  ROGER BLUMBERG A summer 1997 program for high school students Division of Special Programs, Columbia University
http://www.stg.brown.edu/~rog/GS97/
An introduction to some key mathematical habits and concepts not often taught at the precollege level. This site serves as a model for presenting and augmenting a course on the Web.
Over a fourweek session, students examined:
 What is mathematics (for)?: analysis and generalization  The mechanics of mathematical proof  The mathematics of counting  An introduction to the mathematical theory of probability
Roger Blumberg is an educational hypermedia researcher at the Scholarly Technology Group of Brown University, and works on a variety of educational projects, often as part of Brown's participation in the NetTech consortium.

EGYPTIAN AND ROMAN NUMERALS
ROMAN NUMERALS 101  OLIVER LAWRENCE http://www.cod.edu/people/faculty/lawrence/romans00.htm
"The Romans used only seven letters to express all their numbers. The combination of a letter and its position could represent any number. They also use a line above the letter, so the numbering system actually represents our own very closely, with fourteen different symbols. The major difference is how they treat the notion of zero...."
This tutorial includes uses for Roman Numerals (clocks) and a Table of Arabic and Roman Numerals:

ROMAN NUMERAL CONVERSION http://www.ivtech.com/roman/
Enter an arabic number less than 4000, and receive the equivalent Roman numeral.

EGYPTIAN MATHEMATICS  MARK MILLMORE http://eyelid.ukonline.co.uk/ancient/numbers.htm
A summary of Egyptian mathematical symbols and conventions for reading and writing numbers, together with some problems "to see if you could survive in the world of Egyptian numerals and mathematics."
\/
"...Egyptian numerals are essentially Roman numerals, with no fives, or 50's, or 500's... In Egyptian, numbers are longer than in Roman numerals, but arithmetic is simpler. There are fewer "carries" and no "borrows" when adding, so a person might guess that calculation was done more often in Egypt than in the Roman Empire...."

EPIGONE  THE MATH FORUM DISCUSSION SOFTWARE
http://forum.swarthmore.edu/epigone/
The Math Forum's archives now offer fullfledged Web discussions: you can view, search, and post to mathrelated mailing lists and newsgroups from the Web.
Since these Web discussions are updated when each new message is posted, they are as current as a mailing list. In addition, the software threads messages, organizing them by subject, and provides a search capacity.
You can post new messages and reply to those posted by others directly from the Web using the form linked to the Web discussion.
The Math Forum's Web archives are maintained by Epigone, the Math Forum's own Webbased discussion software.
