Start with zero...
||

Add 1
||

0+1 = 1
||
 * [[image:P1260734.JPG width="250" height="145"]]

1+1 = 2
||

1+2 = 3
||

2+3 = 5
||

Now, let's use squares instead of numbers....

**Start with zero... no squares**
||

**Add a 1unit square**

**Add the 2 unit square**
||

**Add the 3 unit square**
||

**Add the 5 unit square**

 * ====Place the green line across the opposite====

corners in each square.... a spiral!
|| ====....It matches!====

Hmmm... does it really? Let's check....

....and my hand!
||

...and my arm!
|| =I am the same pattern as a snail!!!=

Patterns like this are everywhere in nature... just look for spirals in pinecones, in sunflowers...
