A Visit with Susan Addington
Susan Addington is a math professor at Cal State San Bernadino, she has developed math lessons for use on the internet.The address for her work is http://www.math.csusb.edu/faculty/susan/.
Susan is looking forward to working with the teachers in the San Diego Morse Cluster and promised to answer all email math questions.
During the session Susan shared the following information:
- the pictures on her web page were created using a drawing program that was downloaded from the web
- student activity - telling time with your feet. Susan would like to hear from from teachers who use this activity, she would like to collect datta on the height of students in their own feet.
- Clock Arithmetic Pages that use a java applet - the two hour clock is related to evens and odds, evens end at zero, odds at one (mod means the number of hours on the clock).
- Secret decoders often work on the basis of modular arithmetic Using a 26 letter clock because there are 26 letters in the alphabet. The code is determined by a shift of a given number of letters.
- The Number Bracelets Game
Susan is currently working on a number of projects which are still in the development stage.
- Olympic site: http://www.math.csusb.edu/faculty/susan/ocv/ This is a prototype lesson, not ready for prime time.
- Make a Star Polygon http://www.math.csusb.edu/faculty/susan/ocv/star11.html
- More Star Polygons http://www.math.csusb.edu/faculty/susan/ocv/star29.html
- Graph Paper http://www.math.csusb.edu/faculty/susan/ocv/graphpaper.html
- The ImageScribble Applet http://www.math.csusb.edu/faculty/susan/ocv/scribble_on_susan.html
Susan's main aim is to get people thinking about math and maybe even do some, that is why applets are used. For example the graph paper applet is there so that you can do the exercises without going out to look for paper.
