I haven’t been stress-printing before the election, YOU have. Well, maybe you will after this post, at least. Fire up your 3D printer(s) because there are dozens of things you need to print before Tuesday, including each of the 50 states (and DC, which has 3 electoral votes), sized to each have approximately the same area, with heights determined by number of electoral votes.

Fall semester is coming and you’re teaching online… let’s pause for a small scream 😭

Next year we’ll all be experts and there will be no end of talks, papers, and blog posts that we can use to figure out what to do. But right now we need the quick and dirty. What can we do NOW, and fast, to make our online math course content more interactive and engaging? If you’re getting ready to teach math online and your school’s LMS is Canvas, here are 10 quick tips to get you rolling.

Fitted Face Mask for People Who Aren’t Great at Sewing

Fitted Face Mask for People Who Aren’t Great at Sewing https://mathgrrl.com/wp-content/uploads/2020/07/IMG_4724-scaled.jpg 2560 1920 mathgrrl mathgrrl https://secure.gravatar.com/avatar/de00911e0a27aa527aae53a60fc5b663?s=96&d=retro&r=g July 25, 2020 January 4, 2021

Over the past weeks I’ve iterated mask designs many times, acquired a bunch of sewing supplies, and learned from a lot of online patterns and videos. This mask design has a sewn-in nose wire, elastic loops that go all the way around your head, a filter sewn inside the mask, and minimal exposed seams. It’s washable and reversible, so you can decide which side is the outside after you’re done sewing it, or each time you wash it.

Okay. Deep breath. It’s time to start figuring out how to teach online… I mean, how to do Actually Do It Well, not just as an emergency solution thrown together over a frenzied and sleepless week. There is a lot to work to do, so let’s start with something small: online math quizzes. In this post we’ll walk through how to use LaTeX typesetting in both the new and legacy Canvas quiz engines.

Laser Cutting from a 3D File

Laser Cutting from a 3D File https://mathgrrl.com/wp-content/uploads/2019/09/IMG_3030.jpg 640 480 mathgrrl mathgrrl https://secure.gravatar.com/avatar/de00911e0a27aa527aae53a60fc5b663?s=96&d=retro&r=g September 5, 2019 September 20, 2019

To make files for laser cutting, you need two-dimensional information. You could download a picture from the internet, draw something yourself, or create an image in a program like Illustrator or Inkscape. In this post we’ll walk through the process of creating a 2D-laser-cuttable SVG file from a 3D-printable STL file using the free online in-browser modeling program Tinkercad.
