They learn it >after I teach them about irrational and rational roots. I don't know if this would give you more ideas but I wrote this lesson with Nathalie Sinclair and if your students have access to computers you might enjoy having them use the Java Sketchpad applet that she wrote: http://mathforum.org/alejandre/escot/numbers.html >Thanks very much for your patience with this.

I'm just a bit sorry that I'm no longer in the classroom to try some of the ideas with students. >It is interesting how easy it is to demonstrate the squaring >function but to go the other way is much more work. I agree. Please let me know how things progress! -Suzanne A., for the T2T service
