Numbers

This engaging web site contains information and interactive applets related to various number systems: Egyptian, Babylonian, Chinese, Greek, Roman, Mayan, and Arabic. Users learn the history and structure of each system as well as how to count and write numbers. The site also allows users to explore finger systems, calculating machines, other number bases, and "interesting numbers." A series of pages on data and graphs includes information and activities on gathering, analyzing, graphing and sorting data. (Because the section on the Arabic number system is so extensive, it is cataloged separately as a related resource.)

      Great Social Studies and Math Lesson

    • I like how this lesson explores early number systems and the number systems of other cultures. I think this is a valuable resource for engaging students in making meaning of mathematics.

      Impressive

    • This site is a treasure trove for anyone interested in numbers. It is very comprehensive and functional. Teachers should be able to think of many challenges that make use of it. Here's one: The Greeks used their alphabet for both words and numerals. Joanna's name spelled in Greek letters has a total value of over 800, but mine, Robert, comes to over 1300. The applet does the translation and the math. Can you find a 6-letter name with a higher sum?
