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: […]

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 […]

The Last Seat : Car Talk Puzzler

Yet another great car talk puzzler, The Last Seat: RAY: You’re one of a hundred people standing in line to get onto an airplane that has 100 seats. There’s a seat for every person who’s in line, and each of you has a boarding pass for your assigned a seat. The first person to walk […]

Visualization of a Function Through Time

(This post demonstrates the math behind the creation of some unusual math art. I got the idea from this tumblr post which I don’t even think works like this. But it was the inspiration behind the pictures.) Take this function: f(x) = x^2 + a*cos(ax). When you take values of a between 0 and 8 and […]

Madeup and Calculus

The madeup language for creating 3d models came out a week ago for the kickstarter backers. There is more information about the computer programming language found at the kickstarter page. It’s been a lot of fun to play with but looking at it through the lens of being able to create calculus 3d solids has been […]

BetterQs Blog

At TMC 2015 I attended a fantastic session by Rachel Kernodle that encouraged us to improve our questioning in class. I took this goal to heart, in fact, it ended up being my “One TMC15 Thing” that I’d like to work on. #1TMCthing Improve my questioning in class, have students interpret each other’s answers before […]
