I have an actual blog now, with a page where the German Geometry problems are going to live. I've uploaded the previous ones posted here, and future stuff will also go up there. amblingpilgrim.com/geometry-…

Geometry Problems

The problems here come from Geometrische Wiederholungs und Denkaufgaben by Paul Eigenmann (Ernst Klett Verlag, Stuttgart, 1964). This book is rather difficult to obtain outside of Germany: the only…

2%. The % of teachers who describe using AI tools "a lot" has not budged a bit even given 11 months, improved AI models, and lots of teacher PD. Especially if you have "AI" in your bio, I want to know what you make of this. xitter.cf/ddmeyer/status/1853508…
A question - Which of the following best describes your current use of artificial intelligence-driven tools in your classroom? 2% said "I use them a lot" in December 2023 and 2% said the same in October 2024.

In December 2023, 2% of teachers surveyed by Education Week said, "I use AI tools a lot." 11 months later they have surveyed teachers again. Any guesses what % now say "I use AI tools a lot."

This 500-year-old portrait may seem ordinary, but it's one of the most mysterious in history. There's so much detail that you can read every musical note on this small page. But look closer — an unsettling secret is hiding in plain sight... 🧵

For the past several months, I’ve been deeply concerned about Israel’s war in Gaza, thinking about what I can say or do, as an American, as a Jew, as a former Congressman. But one thing is crystal clear: the war must end.

Something that has stayed with me from @smartereveryday 2 roboforming video is that they can fabricate and physically test a part FASTER than a simulation would run. That is A mind boggling B a game changer

Geometry construction problem: given a 24 in side square, layout a regular octagon with the same center and four sides that are segments of the square? How does this problem change depending on the tools you have? How would a carpenter actually solve this? #ITeachMath #geometry

🥳Publication day for #UndergroundMathematics! Thanks to everyone involved❤️ Here’s a short🧵to its main argument: How did practical mathematics and a culture of accuracy developed in EM Europe? Rationality wasn’t just about scholars, it included craftsmen and artisans too!

How does HS math prepare students for college math? What can we do to optimize success? It's a great question - one that we now have a lot of data about. It's complicated & easily-misinterpreted. And what those data reveal is pretty astonishing. Buckle up.. 1/18

So far: reading @hpicciotto website, thinking a lot about tools like patty paper, Geogebra. Also thinking about artisanal math: construction, mechanical, craft, and nautical contexts.
