GeoGebra is Great!

April 27, 2010

I finally figured out how to post GeoGebra applets on Google Sites so that I can link to them from WordPress.com (which does not support them).

The greatest value of GeoGebra, or Geometer’s Sketchpad, or other such packages, in my eyes is their ability to help students dynamically visualize the effect each constant has on the graph of an equation. I find them an invaluable “thinking aid” as I ponder a new equation form, and they help me formulate my own answers to questions such as “why does it do that?”

Check out ones for Linear functions:

Quadratic functions:

Exponential and Logarithmic functions:

Rational functions:

Trigonometric functions:

    Neat stuff. Have you discovered the Wolfram Alpha site yet? http://www.wolframalpha.com/

      Yes! I have dabbled with it a bit, but have read a number of postings extolling its virtues while simultaneously wondering how to make best use of it in teaching.
