The evolution of ideas (an example)

This is a new version of this activity

This activity consists of a text that starts with Tartaglia, Cardano and their competition to find the solution to the third and fourth degree equations and finishes with Complex Numbers and the Mandelbrot Set. It also has some activities for the students related to the text.
In the links below you can find the handouts for the students and the teacher guide. You can also get a couple of videos from YouTube and a GeoGebra applet with interesting representations of the Mandelbrot Set.
