Math educators, where do you fall within the levels of ethical engagement?? arxiv.org/abs/2212.11713 #iteachmath #iteachcs #mtbos

Anyone teach a high school course about Math and Visual Arts? Seeking ideas for the course I’ll be doing next year! #mtbos #iteachmath

Breaking News! Code UFB!!! It takes 2 weeks to confirm ocean sea surface temperatures and the long wait is finally over. The first day in recorded history with Nino 3.4 SST at or above 30.0°C is now officially on the record. October 7, 2026: 30.000°C. climatereanalyzer.org/clim/sst_dai...

Another surprising "seed-42 coincidence" We were reading this: doi.org/10.1057/s415... and noted a mistmatch of data in Fig2 with reported stats (e.g. the SD of x-coordinates for blue crosses cannot be 30 as reported). We extracted the plotted points to investigate... #psychscisky #science

I'm about to claim that there is no data from the last 30 years that lets us characterize how american teachers teach math, that the last reliable info we have is the TIMSS video study...anybody want to point something out before I make an ass of myself in writing?

The Modeling Teacher, AMTA's new peer-reviewed eJournal, is accepting submissions for its January 2027 inaugural issue! Share action research, strategies, DIY apparatus, book reviews and classroom stories. Deadline: Dec 1, 2026 Submit: modelinginstruction.org/ojs-3.5.0/in...

The Association for Human Mathematics (AHM) statement on OpenAI’s October 6 release of mathematical documents just dropped! www.ahmath.org/statements

one of the most beautiful formula in all of mathematics... combining so many of the most important constants... e, pi, -1, i, and 0.04321391826377224977441773717172801127...

The Doink It: A wonderful analogy for how "AI" is being sold in education. Don't build something people want, *tell* them what they want and make them feel bad if they express what they actually want. "As far as I'm concerned, the quality of the toy shouldn't matter when you're selling to kids."

It's back to school this week for many, so this is your annual reminder about draustinmaths.com. There are now over 1200 free maths resources, including over 100 resources for A-level Maths and Further Maths. And when you've exhausted all of those, there are a few paid-for resources too!

New blog post! "Starting Strong: Putting Mathematical Thinking First" in math class this school year. #MTBoS #iTeachMath #T3Learns #MathsToday karendcampe.wordpress.com/2026/08/25/s...

"The Story is Systems, Not Ideas" "What’s more true is that the daily conditions of teaching pull towards meh-ness." "a story that people need to know—that in education, ideas of any sort won’t get you far. What matters is how it’s done."

"The "output" [of human math research] is not just a paper, but the changes that happened in the brain along the way. The "output" is a person who understands something better, and can take that understanding forward in their research and their teaching." -Jonny Evans jde27.uk/llms.html #🧮 🧪 #AI

In the new 2026 CSTA standards, each includes a "Students are not expected to" to help understand what the standard is not. So, what are students not expected to "understand", "apply" or "build"? "math" appears in 31 of the standards! In 27 of those, it appears after "Students are not expected to"

Guess the year! There are some hints in there. "We must teach people not to think of technology as an authority figure. Without mathematical understanding people of the twenty-first century will be victims of computer mysticism". Bruh, math educators failed so hard at this... 😭

The #ProblemSolving Calendar is back! (sort of). Check out the August Palette of Problems to set the stage in math class this school year. #MTBoS #iTeachMath #T3Learns #RecreationalMath #MathSky #MathsToday karendcampe.wordpress.com/2026/08/02/a...

Do archives of the "Math Times Journal" exist @mctm-mn.bsky.social? Particularly looking for this reference from the 1989 NCTM standards: Day, R. P., and R. Scott. "For problem solving: consider using a spreadsheet." Math Times Journal 1, no. 2 (1987): 20-28 CC: @saravanderwerf.bsky.social

ATTENTION EDUCATORS! Interested in invention education? Interested in civics? Join us on Thursday, July 23rd from 1-2 PM for a discussion on ways invention and civic engagement can go hand-in-hand. Featuring Doug Scott and Leigh Estabrooks! #invented RSVP: https://bit.ly/PBSInventionCivics7_23

I wrote about how @hpicciotto.bsky.social makes such wonderful (and useful) mathematical activities. substack.com/home/post/p-...

We're putting together a toolkit for teachers who want resources for a more techno-skeptical critical AI literacy. If any K12 educators are willing to share their thoughts on this topic, we'd love to hear from them. Thanks! criticalaitoolkit.org/survey/ #edusky

Hi! In July I'm once again running a free online program for K-12 math teachers called "21st century mathematics". Its goal is to help teachers to connect math they teach with some math that has been discovered in the 21st century. Pass it along! Info+register: justinlanier.org/21st-century...

Please Use AI

"They're trying to do the thing in a way which is so general, that they can't possibly build on that. If they build on that they're building on top of confusion and vagueness." -- Bill Evans Wonderful description of how important it is to take your time when learning and build a good foundation.

Excited to be named a CSTA Responsible AI Fellow.

This month marks the 20th anniversary of my entering the classroom as a teacher! I was just going through a folder from my first Computer Science course (2009) and am not surprised by myself. Class #1 was "Ethics" #TeamCompSci #ITeachCS #CompSci

Here are some of my favorite #ProblemSolving questions from the April Calendar... April 9: decimal expansion of 1/17 April 14: square roots of square roots (Check out Really Radical post for more!) April 28: shortest path in a circle and square #iTeachMath karendcampe.wordpress.com/2026/04/22/r...

I never met Dr. Nancy C. Dunigan, but I have a copy of the 1981 NCTM Yearbook that once belonged to her. I occasionally get a used math book and can find information about the previous owner. She sounds like a real swell lady and dedicated educator. www.dignitymemorial.com/obituaries/l...

It looks like there are some amazing presentations from teachers in the program for #NCTMDen26. I'll be presenting on the importance of computing in mathematics and how basic familiarity with a numerical computing platform can open up new worlds of beautiful mathematics. #ITeachMath #mtbos

What does it look like to critically examine AI in the middle school Computer Science classroom? www.civicsoftechnology.org/blog/introdu...

I'm not joking when I say mRNA technology is more important than "AI" and it's a tragedy we're throwing billions into one while our government is aggressively defunding the other.
