## 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”. Freese’s Transformation also shows this relationship, but his “squares” all have sides sqrt 1, sqrt 3, sqrt 5, and so on. Freese Corel File, Adobe Illustrator File, Jpg printable

## Take and Make: Experimental Mathematics Cucumber Edition

Here’s a fun one! Inspired by a conversation with Chris Daniels of Public Math. He said roll paper around a cylinder and cut on an angle to get an ellipse and produce a sine wave. So we did! And you can too. Then you can make a roller from ellipses, reflect your sine curve and roll the elliptical roller along

## Take and Make: Freese Transformation 178

This design is from a lost manuscript of Ernest Irving Freese found by Greg Frederickson and published in his 2018 book “Ernest Irving Freese’s Geometric Transformations: The Man, the Manuscript, the Magnificent Dissections” Frederickson mentions Freese’s manuscript in the bibliography of his 1997 book, “Dissections: Plane & Fancy, and included selections from it in a 5-part series of short chapters spread

## Take and Make: Tower of Hanoi

Ximena Garcia made a laser design for the Tower of Hanoi puzzle. You make two of each disk and glue them together for nice chunky pieces. We use dot stampers (for bingo sheets) to color the wood. Works great! The laser files are in this folder on our webpage. Tower of Hanoi is a model of exponential growth – number of

## International Day of Mathematics

The University of Texas and MathHappens Foundation participated in the first international day of Mathematics. Check out the video contributions from Dr. Jennifer Austin (inside the main video at minute 3 and Ximena Garcia featured video. In case links change, you can also see Ximena here.

## Take and Make files are spreading! Fantastic!

It is very exciting to see our files being used and the great results! Gotta love the math and maker communities on twitter! Thank you @MathHappensOrg https://t.co/yJ63LBiqJp — Ralph Pantozzi (@mathillustrated) March 13, 2020
