A Golden Ratio Activity and
Resource par excellence!

1) Scroll below for a neat 2-page Golden Ratio activity (It will take some extra time to finish loading -- while that happens, read on). Select each page of it at a time and print it for use with students.

2) Or, if you have been searching for any of the following keywords, a click on one will take you to an excellent book resource (A Mathematical Mystery Tour) for weeks of personal, home, or classroom learning about the Golden Ratio and Fibonacci Numbers:

3) Or you can go to this website and see a selection of creative books, links, and information on math learning that goes beyond these topics: Mark Wahl Learning Services and Books.

Now, the Golden Ratio. It has fascinated layman and mathematician for centuries. It seems like magic that it turns up in such different arenas as pine cones, earth-moon and planet relationships, the Cheops Pyramid in Egypt, the Mona Lisa and even our DNA. Indeed its widespread appearance shows that there is a unifying mathematical principle that is more subtle than science has thus far been able to define.

Below the line is an activity that is two pages long, of interest to students aged 10-adult and that requires about fifth-grade math knowledge to successfully complete. Feel free to select a page at a time and print the selection for use in a classroom or homeschooling setting. It is one of many from my popular book A Mathematical Mystery Tour.
Enjoy!
