In 2019, we brought our suite of Navigation Math to New York to share how we relate math to Texas History and the voyage of La Belle which is on exhibit at the Texas State History Museum.  Files to make our version of the Parallel Ruler are here.     Files to make our version of the Compass Rose are here.

Elizabeth Lay, Claire Steffen and I had the opportunity to present a webinar through the Texas Historical Commission today.  We discussed ways that museums can  enhance visitor experiences with math, showed a variety of examples of math activities at museum locations and talked about our process in developing connected activities.

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.

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

Women in Mathematics!  Katherine Johnson calculated trajectories, parabolic and otherwise for NASA in the 1960s.  Almost 70 years earlier Mary Boole invented curve stitching to teach the mathematical properties of parabolas to children.  We made some really great foldable parabolas to connect to the work of both these women in math.  Here’s the laser file – we cut the holes

Super simple and yet kind of cool.  You need a machine screw, a wing nut, some scrap wood about 4″x.5″,  and some stretchy elastic.  Directions and Files Here.  Check the video on Twitter to see how it moves. Article from American Mathematical Association here. Also if you don’t want to make from scratch, we could send you the parts.  Fill
