Take and Make: Sum of Squares of Odd Numbers – Freese Transformation
This Geometric Transformation shows how the sum of the first 6 Odd Squares is the square of 6, or 36. Its the classic “proof without words”.

What is it?!
Math Happens… just about everywhere. This is a very old hoof gauge that we found on a trip to Sheridan, Wyoming. It looks like good luck and math mixed together. The arm of the hoof gauge moves up and down. The arrow points to the measure. A healthy angle for a horse hoof is approximately 54º. Many experienced farriers know
