## The Internet: A Tool For* * Teaching Mathematics **

There are many different styles of lesson plans in the traditional mathematics classroom. Factor in the Internet and the diversity explodes!

Here you will find examples of lesson plans that utilize the Internet in one (or more) of the following ways:

• The WWW as an information and data resource
• Student collaboration and data collection via e-mail
• Fully guided activities on the WWW

### The WWW as an information and data resource

• Tracking A Hurricane
Students learn to plot rectangular and polar coordinates, a lesson designed to integrate the use of the Internet into instruction of Precalculus topics

• The Spanky Fractal Database
This is a collection of fractals and fractal related material for free distribution on the net.

### Student collaboration and data collection via e-mail

• Eratosthenes Finds Diameter of Earth!
Students estimate the diameter and circumference of the Earth by repeating Eratosthenes’ experiment. Email is used to exchange measured data and results. The WWW is used to research the mathematical and scientific contributions of Eratosthenes.

### Fully guided activities on the WWW

• A Fractal Lesson
Learn what a fractal is, make one yourself, then look at fractal resources on the Internet in this lesson for elementary and middle school students.

• Playing the Market
This lesson uses the Internet to research a company in the stock market. Students find a description of a company and its products and a report of its earnings during the past year. They track stock data and analyze and graph it using Mathematica.

If time permits, browse this collection of Science and Mathematics WWW sites.
