California ran out of license plates of the form 1ABC234 so I was curious, how many license plates did we go through?

Okay I MIGHT have found a new way to visually obtain the harmonic mean because I could not find this visual anywhere. Even if it's not new, I'm still really proud of it because it's understandable and valid.

The headline: "AI tutors do just as good as humans at half the cost." The appendix: "We threw out a bunch of students who didn't use the AI tutor enough." Me: "You see how this looks right." Study: arxiv.org/pdf/2609.28470

Did you know that Mike Flynn has a YouTube channel where he shares videos for math educators? Here are three of his most popular videos: youtube.com/watch?v=UzjZXLyu… youtube.com/watch?v=q_F_L7Yj… youtube.com/watch?v=MBCktTpu…

Stop buying more counters. Use the children.Five kids, photographed in every decomposition of 5, posted at eye level all year. Decomposing number is THE conceptual achievement of the early grades (Resnick, 1983), and the body makes it stick. Zero dollars. Huge payoff.

Mathematicians are angry at AI solving their problems, and it's easy to dismiss this as gatekeeping. "A proof is a proof. They just want to keep their jobs / prestige / fun !" But I do think mathematicians have a point, and I'll try to explain using old Civilization-style maps

It's all over tech-adjacent Twitter. "Kids can learn 2x ... 5x ... 10x! ... faster than in regular schools." My question, always, is "... learn WHAT?"
Several tweets indicating that students are learning 2x, 5x, or 10x faster than regular school.
