I think this material is *very* well structured and packed with just about all that one could imagine about Fibonacci Numbers and The Golden Section and more! I spent about a good 45mins to an hour on this website, reading up how Fibonacci # can be found in various ways. The Rabbit Sequencing was very interesting and I liked the activities that went along with it too! I enjoyed reading about the history behind the man, and controversy over the theory. The quality of the materials is outstanding, very well thought out and clearly represented in a manner that is easy for all levels to appreciate. I have no doubt that students would benefit from using these materials to build a foundation of knowledge on this subject and explore new things too.
I believe that first time users those less 'tech-savvy' would have no problem using this site. It's straightforward, point and click!
