Phi: The Golden Number


Age Range: 9-18 (Grades 4-12, with parental supervision)


This website is devoted to the exploration of Phi, an irrational number like Pi that is the ratio of the line segments that result when a line is divided in a special way. You’ll find many demonstrations of Phi along with its history from ancient Greece and Egypt, to the Renaissance, to modern day with its appearance in quasi-crystals — a form of matter discovered in the 1980’s.

Use the menu to see Phi demonstrated in many different areas including: 

  • Design/Art – Phi is in Art, Architecture, Color, Music, Poetry, Marketing, and even Credit Cards.
  • Life – Explore Phi in Human Anatomy, Animals, Plants, DNA, and Population Growth.
  • Mathematics – Including Means, Fibonacci Patterns, Pascal’s Triangle, and more.
  • Geometry – Look for Phi in Bucky Balls, Circles, Triangles, Orthogons, Quasi-crystals, Spirals, and more.
  • Markets/Gaming – See how Phi and Fibonacci numbers are used to predict stock market moves.
  • Cosmos – Phi appears in the Solar System, Universe, Quantum Matter, Quantum Time, etc.
  • Theology – See a demonstration of Phi in the Bible.

This is an ad-supported website that provides a fascinating demonstration of mathematics (and particularly Phi) in all aspects of life. It is beautifully illustrated and clearly written.

SMILE: Mathematics


Age Range: 5-18 (Grades K-12, with parental supervision)


This website archives lessons from the Science and Mathematics Initiative for Learning Enhancement (SMILE) program that trained teachers and educators in effective classroom and lesson presentations. Participants contributed tried-and-true lesson plans in Mathematics (as well as Biology, Chemistry and Physics) for elementary and high school grades that you can print out and use for free.

When you get to the website you’ll see a brief introduction and an icon menu. Click on the RED circle with the word “Mathematics” underneath it. A new page will open containing a menu of math lessons divided into the following categories: 

  • Geometry and Measurement
  • Patterns and Logic
  • Probability and Statistics
  • Recreational and Creative Math
  • Practical and Applied Math
  • Arithmetic
  • Graphs and Visuals
  • Algebra and Trigonometry
  • Miscellaneous

Click on any lesson and a new page opens with the objectives, a list of materials required, and instructions or strategies on how to present the lesson or activity. 

The lessons and activities are not obviously sorted by grade range – so you’ll need to read through the titles to determine which ones will be better suited for your particular child/student.

There are no bells and whistles here, and no multi-media enticements. This site just offers classroom-tested lessons and activities that you can print out and tweak for use offline at home.

Just FYI: We opened quite a few lessons and found an occasional “rogue” incomplete lesson. Don’t let that deter you from using this resource.
