## Mathematic Mistake – Car Talk Puzzler

RAY: Everyone, almost everyone remembers the Pythagorean Theorem. A squared, plus B squared, equals C squared. And there are numbers like three, four and five; five, 12, 13 which satisfy that little equation.Many hundreds of years ago a French mathematician by the name of Fermat said, this only works for squares. There is no A cubed […]

## Classroom Top Four – #4 Interests and Interesting Things

Previous entries: #1 Course Evaluations, #2 Whiteboards and Furniture, and #3 Teacher Technology Use. This one is short and sweet. And it totally depends on you. Share your nerdy math things with the students. Please. Students at any level should see how you enjoy the subject that you teach, and how you’re interested in math other […]

## Classroom Top Four – #3 Teacher Technology Use

Ok, here we are after a full year between Classroom Top Four #2 and #3. Wow. Good news is that I have more refined opinions on this specific topic, partly because I changed schools and the friction of the change has made me more thoughtful about what I’d want in an ideal classroom. Previous entries: […]

## Mathematician Once Removed

This post is part of the Virtual Conference on Mathematical Flavors, and is part of a group thinking about different cultures within mathematics, and how those relate to teaching. Our group draws its initial inspiration from writing by mathematicians that describe different camps and cultures — from problem solvers and theorists, musicians and artists, explorers, […]

## Learn to Code through Math #learntocodethroughmath

The #learntocodethroughmath project is something that I created sort of by accident. I see the audience for this project as someone who is somewhat comfortable with using Desmos to create math-artsy stuff with lists, functions, and parametric functions and is interested in learning how to code using Processing. So yea, pretty narrow. But hopefully fruitful […]

## The Rough-Draft Move

I’m baaaaaaack. My last post on this blog was six months ago, and that’s a shame. I’m shifting my “writing bucks” from the photo180 blog over to this blog. Some posts will feel a little photo180-y, but most will be more “fully featured”.  Removing friction from the learning cycle in a classroom is super important. […]

## PAEMST State Finalist

I’m happy to let you all know that I’m a New York State finalist for the Presidential Award for Excellence in Math and Science Teaching (PAEMST). I worked on the application this past spring. I enjoyed the reflective nature of the application; it required a detailed description of a recorded lesson, and also a detailed […]

## Classroom Top Four – #2 Whiteboards and Furniture

This is the second in a series of four posts that describes my favorite things that I’ve done in the classroom to improve my teaching. The first post on Course Evaluations can be found here. 2. Whiteboards and Furniture On my classroom photo blog, photo180.recursiveprocess.com, I’ve written a LOT about my class’s whiteboard use. In […]

## Classroom Top Four – #1 Course Evaluations

This is the first in a series of four posts that describes my favorite things that I’ve done in the classroom to improve my teaching. This post was cross-posted on my photo 180 blog.  1. Course Evaluations Have you ever tried to swim in a lap pool with your eyes closed? How long were you able […]

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

This is an extension off a previous workflow series featuring Processing and Fiji.  This 3D print has slices that represent a (linear) trip in the Julia Set from 0+0i to 0.32+0.64i. I wrote a Processing program to create the 400 Julia slices and then Fiji stitched the 2d images together into a 3D model. Here’s the […]
