My specialty is taking the talk-heavy instructional routines that work so well in K-8 math and using them in K-8 computer science (where they are an absolute *revelation*). My #NCTM session is a hands-on tour of those. I love showing math teachers (often CS-adjacent) how well they work. 🤓

The CS department at Cal Poly is looking to hire tenure-track professors in two searches.

Come with work with us!

General position: jobs.calpoly.edu/en-us/job/55...

Data Science (within the CS department): jobs.calpoly.edu/en-us/job/55...
Cal Poly - Details - Assistant Professor - Computer Science and Software Engineering (AY 26/27)

Someone just mentioned this to me, but in CS. Can track it down if helpful.
Is this why I found my first NCTM so 💖-filling? Because the whole family tree is there at once, and they’re all just so good and easy to talk to? 🥹
YESSS, gang… we will teacher-move until every teacher move in the book has been moved. #MathRoutine #mtbos
Just like before, I'm saying it on social media for accountability...

THE MATH ROUTINE COLLABORATIVE IS COMING BACK!!!

Mark your calendars for January 2026!
This was a terrific series of slides! So simple, but such good fodder for planning & discussion.
This is a great idea… but ok if we get some sleep first? 😅🥱 What a week!
Haha, right there with you. 😅 Two for me today: an animation that didn’t animate and a missing thank you. New personal best! ✨
And honestly, *every* one of these brilliant people is doing something I want to steal.
I mean borrow.
Definitely Borrow.
There are some people that are just fun to have in your session cuz they’re smart and thoughtful and active and up for being stretched. Thanks, @sneffleupagus.bsky.social 🤗
I'm so so so so happy to see @mdeutschmtl.bsky.social this morning. 😍 #NCTMATL25
Hahaa, it’s not just me?! 🤣
Every time I was with Shelby your name came up. Stalking accepted, & back at ya! 😶‍🌫️
Ah. Apparently the plan is:

- Get your talk accepted at the conf that’s the source of your ideas 💖
- Let 8 months go by
- Exhaust yourself in the happy, nerdy buzz of that conf
- Collapse in your hotel room
- Wake up at midnight
- THEN finalize your presentation for the final morning.

Has this ever happened to YOU?

Me: Oh! You do [my niche] too? Cool! I’d love to show you my take on it! Come to my session VERY EARLY ON THE LAST DAY of the conference. 🤗

Them: Um, can’t. Not sticking around.

Me: Oh. 😔
... and the chain of thought you were shown is just LLM self-chatter, right? Not made of any different stuff than the rest of it.
"... folks will give you their speculative guesses as to why ChatGPT 5 gave [an incorrect result]. But these are all made up rationalizations after the fact. ... No one can predict when or how AI will fail for a given prompt without running the prompt." 💖
Declining to answer, out of respect for its boundaries. Refreshing. 🙃
Not bad—a rather selective 2 for 2, ones whose authors/speakers I’d seen and liked. T-shirt from one, materials from the other. (Ok, I grabbed a few stickers too 😜)
FedEx a few blocks east. Used it yesterday. Not open super late.
Is there anything in the world so simultaneously exciting with promise and dreary with mediocrity as a tradeshow floor?
(Apropos of nothing…)
Whoa... 😅 a whole first day of #NCTMATL25 and I've got pages of notes, dozens of pics, plenty of handshakes and hugs and "awesome to see you"s and "your work is amazing"s ... but I haven't made a single bsky post? Have I lost my touch!? #not2018anymore #mtbos
Lovely, clear column there -- and a welcome callback to the cogsci ideas I learned in 90s undergrad. Great pull quote: "Right now, it feels as if Big Tech is throwing general-purpose A.I. spaghetti at the wall and hoping that nothing truly terrible sticks."

I read ~10,000 teacher prompts they made to #AI
At #NCTMatl25 Friday @ 1pm, come hear what I learned about how and why math teachers use #AI for their classes, and how that can improve your use.

So excited to be speaking at #NCTMATL25 in Atlanta! Thurs, Oct 16 | 9:45-11 with my friend Kim Rimbey. Our session, Subtraction is the Achilles Heel But Don’t Need to Be provides answers to help all children understand subtraction. #NCTM #MathEd #ITeachMath #ElemMathChat

Hey #NCTMATL25! Want to start your conference with some math thinking? Join me at 8 am Thursday (yes, in 8.34 hours) to explore dynamic quadrilaterals. Were you at #NCTMGameNight? My session’s in the same room.
It is! Starting small, but with hopes of helping lots of folks make sense of code, together. ☺️
