A knight's tour of a 32x32 chessboard. The knight's path can be traced without lifting one's writing implement from the surface of the paper. This tour is close to having 180-degree rotational symmetry and vertical and horizontal mirror symmetries. #mathart #mathsart #chess

A knight's tour of a 32x32 chessboard. The knight's path is unicursal. If you start in the lower left corner and follow the path move by move, you will visit each square once and only once and end near the lower right corner. Inspiration: Szpakowski's linear ideas. #mathart #mathsart #orms #chess

As the year ends, pause: What math stories did your students write—not just in numbers, but in courage, struggle, insight?
Growth isn’t always a score.

What did they teach you about math, learning, or yourself?

Doodling in Math Class: Infinity Elephants This is "Doodling in Math Class: Infinity Elephants" by Vi Hart on Vimeo, the home for high quality videos and the people who love them.

I learned from her Patreon that Vi Hart has just deleted her 1.5M-subscriber YouTube channel. The worsening of YT’s policies for creators finally reached her breaking point. To help herd folks to her videos’ new home, here’s a link to an early favorite of mine.

I will pick 3 different digits, and use them once each to make a time. Then, I’m going to use the same 3 digits to make a different time. I will then work out how many minutes between those times.

The goal is to find the shortest elapsed time using these rules.

2025 is approaching so here's a fun math fact about that number:

2025=2024+1

This is fun.

Great wonder and exploration here! There's so much fun to have with quadratics; here are just a few nonroutine problems I put into Desmos folders 📂:

Page of class dictionary showing the word banana in Spanish, Ukrainian and French

Last year I started a dictionary reflecting languages at our school speak. Kids periodically add to it, sometimes during centers, sometimes they stop by to add an entry :) #abar #Edusky #langchat

This one was a lot of fun.

Here's how it played out in the classroom.

My cousin was a rower at MIT! ❤️

Whoa! I love this because it will bring a math investigation home!! Please send me more investigations!!

Thank you for an amazing presentation!!

Here’s some cool stuff you can do with Bluesky It’s not just an Alf pics repository.

I learned some stuff about Bluesky I did not know by reading this.

Maybe worth passing it on to others so we can all start getting the full benefit of the 🦋.

Yes please.

A google slide that says "Claim, Evidence, Reasoning (CER) - Clearly define for students what you expect from them when solving problems."

Dr. Pam Seda (@pamseda1.bsky.social) aligned science's CER to math and I CANNOT wait to implement this with my students!! So many anchor charts are coming!!!! #MathMomentsSummit #iTeachMath #mtbos #EduSky
