- Reposted by Tim ChartierOne superpower #math gives me is the ability to picture an interesting object in my head, spark up #Mathematica, and within a few minutes figure out how to make it "real." It's intoxicating! (code in ALT)
- Was watching the Game of Thrones spin-off and saw mathematical designs. Decided to try one. This isn't what I saw but what I made AFTER I made what I saw!
- Went out to eat, saw a pattern on a tapestry, took a picture, and came home and replicated it in python! Gracious!
- It snowed… so naturally I started thinking about slope. ❄️🐇 Horizontal: ski across. Vertical: fall down. That’s the whole slope story.https://youtu.be/_TdNhrS4RXA?si=yFmSNRksi6-actZw

- My son is teaching one-on-one in an elementary math classroom. I've been making animation and puppet videos to support his work. Here is a video on Greatest Common Multiple. youtu.be/K9qpGEiFYn0

- I love when a simple image helps students stop “trying to remember” and start reasoning. Skiing for horizontal. Falling for vertical. It sticks because it makes sense.
- What’s the slope of a horizontal line? What about a vertical one? Horizontal is like cross-country skiing Vertical is like falling. Math is easier when you can feel it. youtu.be/vxIOoZttoPI

- Turns out math behaves better when everyone waits their turn.
- PEMDAS isn’t about memorizing an order—it’s about avoiding chaos. Bob the Counting Sheep gets a visual explanation (with a little help) of why order matters in math. More sketches at Math Figures: www.youtube.com/@mathfigures... #iTeachMath #MathEducation
- I’ve also posted just the animation (no characters) as a classroom-ready clip—easy to pause and talk through why order matters. youtu.be/WcPEIub-Gas

- Mathematics takes “almost” seriously.
- What does it mean to get closer and closer and closer to zero without arriving? In mathematics, approaching can matter—even without arriving. More sketches at Math Figures: www.youtube.com/@mathfigures... #iTeachMath #MathEducation #MathArt

- One of my favorite moments: When Clara saw the video of Zippy and jumped into showing him the correct reasoning. And THAT became the video!
- Zippy thinks he’s good at math because he’s quick. A second grader shows him where he went wrong. Speed isn’t understanding. Thinking matters. Videos appearing at: www.youtube.com/@mathfigures...
- I put just the Zippy clip on the channel as a classroom-ready resource—easy to pause and ask, “What went wrong here?” youtu.be/l74WoFSDodw

- A small Sunday thought: a function keeps its promise. Same input → same output.
- What is a function… and what definitely is not? 🤔 Puppet Dr. C introduces a very pushable example: touch a button → get a predictable result. Math with puppets, clarity, and a little mischief. ▶️ More videos coming soon: youtu.be/yn3hPqJQBs8 #MathEducation #ITeachMath #TeachingWithJoy

- This was a pleasant oops. I was making a curve of pursuit on the square and had it doing the pursuit on three of the edges rather than all four. A happy mistake!

Cheers to 10 years of making videos 🥂 - I made the Today Show yesterday for the math of playing Powerball. Enjoy!!! And yes, someone won. Once it hits a billion, there are enough tickets purchased that it is at least a 50% chance of a winner. youtu.be/3zDTVeooDD4
