Lesson from the web

During a two week summer session at Bryn Mawr College, Philadelphia public school teachers were introduced to the internet. During this two week session they were introduced to many things. Some of these things were fractals, testallation and the serpinski triangle. As part of the final assignment, we were to write a lesson plan and somehow tie it to the web.

Nora, Leon and I will present a lesson to to you on Pi. This is a math lesson for students in grades 7-8. Our connection to the internet is that of getting our lesson from a math web site. These sites are very interesting as well as helpful. Some of those sites are very specific. We found one of the most interesting sites to be THE MATH ARCHIVES. The web address is http://archives.math. utk.edu/k12.html. The Math Archives contained K-12 Teaching Materials from different web sites.

There are a number of other similar sites The following are Internet sites which contain a wide variety of materials which can be used in the teaching of mathematics at the K-12 level. The materials were organized into the following categories:

1. Lesson Plans

2. Schools

3. Software

4. Other internnet sites

Lesson plans are from five different sites . These sites include:

1. AskERIC Lesson Plans

2. Big Sky Telegraph Math Lesson Plans

3. Columbia Education Center

4. Mathematics Lesson Plans and

5. Computers & Maths Teaching We would like to present a lesson to you that we down loaded from Columbia Education Center. Nora will continue our presentaion with a lesson. b. Lesson TITLE: Discovering Pi AUTHOR: Jack Eckley, Sunset Elem., Cody, WY GRADE LEVEL/SUBJECT: 5-7, geometry

OVERVIEW: Many students tend to memorize, without understanding, formulas that we use in geometry or other mathematic areas. This particular activity allows students to discover why pi works in solving problems dealing with finding circumference.
