Its amazing but the Golden Mean, Golden Section, Fibonacci's Sequence and Fibonacci's Ratio just keep going on and on.... In the last lesson you will be looking at the actual mathmatical formula that gives you the Golden Section.

Ready:
The previous formula is used to determine if a rectangle is a Golden Rectangle or not. Take a look at the following link for more information:

Set:
Get your partner, ruler and journal and measure at least three different rectangles in your classroom.

Go:
You and your partner use the formula to mathmatially figure out if there are any Golden Rectangles in your classroom. Be sure to show all of the steps in your work in your journal.

Hint: You may want to use a calculator in this process to be accurate. Also, the 1 is the long side of the rectangle (second number in the sequence), while the 2 is the short side. Also, your product will only be close to the ratio, not necessarily exact.


Next step: Written reflection...
