Internet Links

Following are links to Internet resources that can be used to support instruction of the Math World feature for this chapter.

The Origins of Metrology
This site offers insight on how the ancient Mesopotamians and other cultures measured four quantities: length, area, volume, and weight. This information is provided by Brown & Sharpe, manufacturers of measuring instruments.

U.S. Metric Association
This site promotes the use of the metric system in the United States and offers conversion tables and much more information, including information about NCTM standards regarding the metric system and metric teaching supplies.

Foreign Exchange Rates
Kurt Swanson, a student at Lund University in Sweden, has created this site to display current exchange rates. U.S. Dollar has already been selected, so just click the link for the currency you wish to exchange, and you'll get the conversion rates to and from U.S. dollars. Make sure students understand which rate they need to select to convert their currency. Are they converting money into U.S. dollars or from U.S. dollars?

CNNfn: Currencies Market
CNN financial news provides recent rates for business needs. Look up the geographic region of the country and find the name of the currency on their tables, and start converting! These rates are only for converting U.S. dollars to foreign currencies. You may ask your students to calculate the rate from their selected currency into dollars.

The United States and the Metric System
This National Institute of Standards and Technology provides this site with some history of the metric system, common questions, and some useful graphics that help teach the relationships between metric and customary measures.
