Play with Math

Learning ∩ Play ∩ Math ∩ Art The connection between learning math and playing with math has been on my mind lately. Another connection that I’ve been thinking about is the interplay between math and art. This morning I decided to merge these two thoughts. I originally tweeted under the hashtag #playeveryday, but future challenges like these will be under […]

Workflow: Desmos -> Selva3d -> 3D Printer (in 5 minutes!)

This is a continuation of the workflow series: part 1, part 2, and part 3.  This workflow was done entirely in the web browser and could be done on a chromebook. The only step that requires a more serious computer is sending the file to your 3D printer. Also, writing up this blog post took three times longer […]

Workflow: Desmos -> Inkscape -> Laser Cutter

This is a continuation of the workflow series: part 1 and part 2. Motivation Have students create mathematical art in Desmos and bring that digital art into the physical world using a laser engraver. You can certainly bring any image from Desmos and engrave it into an object using a laser engraver, but this method allows […]

Workflow: Desmos -> Processing -> Fiji -> 3D Print

Note: this post is a more advanced version of the previous post and uses slightly different software. All this software is free and open-source. In this post I’m going to outline how to use a workflow to go from a desmos sketch to a processing sketch to Fiji to a 3D file. The basic idea of […]

Workflow: Daily Desmos -> Desmos -> Madeup -> 3D Print

The seniors don’t go to school on the last day, so I had calculus class on Friday with one student (a junior). We went down to the innovations lab to create things. Here’s what we worked on: Took this sketch from dailydesmos: I had the student work on the solution after talking about superellipses (or […]

Thoughts on the Intersection of Math and Programming

I’ve been interested in the intersection between Math and Programming ever since I taught my first programming course 12 years ago (call it coding, CS, whatever you’d like). I think I’m finally starting to figure it out. Maybe. I was prodded by Dan Meyer and Julia Tsygan to think more in detail about this intersection: […]

What to do post AP/IB exam?

With the IB exams coming up soon, I’ve started to put more thought into what we should do after the exams (we’ll have 8 blocks or so). For the past three years we did free-form math projects and last year they even wrote up great blog posts about their projects. But due to less time left […]

The Mango Gates – Puzzler

From Car Talk: RAY: This Puzzler came from Kevin Tobin. A maharajah owned a mango tree that had very sweet, abundant fruit. People would come from miles around to pick the fruit. So the maharajah decided to protect the tree by erecting a series of seven concentric fences around it. Each fence had a gate […]

3d Representation of Dog Chase

Not what it sounds like. The four dog problem from Steve Strogatz: N dogs start in the corners of a regular N-gon. Each runs directly toward the dog on its left. How far do they run before colliding? — Steven Strogatz (@stevenstrogatz) October 27, 2015 Here is how it was used in my class. Halfway […]
