A few people have asked how I made the fabric hexaflexagons.
Here is a rough tutorial. The one I made above is cotton fabric with directionality. The one I make in this tutorial is felt – those tend to be very durable. Continue reading “How to: Fabric Hexaflexagons”
Math on a Stick is easily one of my favorite things…in the world. That’s not hyperbole. I really love it that much. The 3 days (2 last year, and then this morning) that I’ve volunteered for it have been among my favorite times as a teacher.
It. Is. The. Best.
Here are 3 reasons why: Continue reading “Math-on-a-Stick!”
I’ve had my first day back. I’ve met with new colleagues at a new school. We’ve started making plans. I’m full of hope and belief in the new year, but I can already see the mountain of work ready to bury me in its immediacy and distract me from my goals.
Thus, I’m stating my goals here so you can all hold me to them. If you have ideas or thoughts about them, I would love to hear what you have to say. Continue reading “The Dream – Help me out here, #MTBoS”
This is a pretty specific post. You’re all welcome to it, but it’s likely only helpful for Minneapolis Public Schools Advanced Algebra and Geometry teachers.

UPDATE: The Mathematician List is now an awesome table. Check it out and thank John Stevens and Jedidiah Butler. I’ll continue to update and improve it.
Here is the presentation from NCTM Regionals in Chicago
What is the Mathematicians Project?
The Short Version:
- We as math teachers tend to only talk about white male mathematicians.
- Most of my students don’t look like that, and thus, they have few mathematical role models they can identify with.
- Take 10-15 minutes a week to research (read Wikipedia, that’s all you need) a not-old-dead-white-dude mathematician, and then take 5 minutes in class to tell your students about them. Include a picture. It’s worth it, I swear.

I’m teaching geometry this year and want to have a deeper understanding of how some things are constructed. This has led to a borderline unhealthy binge on Geometer’s Sketchpad. Thus, here are a lot of gifs. I hope someone can make use of them. If you are looking for one and can’t find it, request it in the comments. No promises, but I’ll do my best to make them if it’s in my skill set. OR if you have suggestions on how I could do any of these more effectively, let me know. I’ll update this as I make more gifs.
Constructing a circle through 3 points:

My musing, a blogpost, and an Invisibilia episode have lead me to think seriously about the importance of how I welcome students and families.
A couple weeks ago, I posted this on twitter:
I had been thinking about a student of mine. A previous teacher had mentioned that his questions were “interesting”, which lead him to stop asking questions. I’m sure the teacher meant well by the comment, but it made our student think that he was asking the wrong questions. So he stopped.
I wonder how many times I have done that.
