Space-Filling Terrazzo – Getting Started

 Space-Filling Terrazzo – Getting Started 640 480 mathgrrl

This is the first in a series of posts about a space-filling riff on Tinna’s Terrazzo Afghan. Our design is going to start off looking like one of Tinna’s Terazzo squares, but it’s going to continue as a larger and larger square, with lots of different but “space-filling” patterns along the way. It won’t be ONE space-filling curve (sorry, math geeks), but it will fill space efficiently as we build the pattern out from the center.

Electoral State Stackers

 Electoral State Stackers 2016 1512 mathgrrl

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.

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

 Fitted Face Mask for People Who Aren’t Great at Sewing 2560 1920 mathgrrl

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.

 Using LaTeX with the New Canvas Quiz Engine 800 601 mathgrrl

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.
