## 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 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

## Women in Steam at the Thinkery

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

## Take and Make: Hinged Parabola Stretcher

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.  We cut ours on a Helix laser cutter.  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

## Take and Make: Laser cut 3d Tangrams

Viang Shah created his own Corel Draw file to make this design.  You are invited to make your own design files or use his which are posted in Corel, AI and SVG formats.

We are always excited when makers and maker spaces make our math models!  Patrick Benfield outfitted some 8th graders with Quadrants (or Clinometers) and put this post on Instagram (click on photo below).  Be sure to scroll through and also check out Patrick’s other work.  You can find the files to make this here.

## Take and Make: Pythagorean Puzzles are a hit in Middle School

Lauren Siegel1 Comment

These two Pythagorean Theorem Puzzles were a hit with Paola Garcia’s middle school students.   Paola mentioned that some students who are not as facile with pen and paper exercises excelled with the wooden puzzles and that overall everyone enjoyed them. Laser cutting files are posted here.   These do not have the solutions etched into the board

## Take and Make Proportional Calipers and Golden Ratio

If you want to check Baby Yoda among other structures real and imagined for proportions, especially the Golden Ratio, get these files for Corel Draw, or Adobe Illustrated or there’s an  SVG.  Let us know if you need a different format or other help and we’ll see what we can do.  We use baltic birch 1/4″ thick.  You can adjust
