@NYTimes.com: There are so many issues with this article. How do you ask 37 experts how to improve schools and NOT ask a single classroom teacher? No wonder their list of ideas is so jarring to anyone who spends time in a classroom. #MTBos #edusky www.nytimes.com/2026/09/28/u...

I've been making CII (Correct, Incorrect, Incomplete) tasks to deepen students' understanding of particular topics. First, they discuss the Correct work in groups and I ask them questions. They do the Incorrect column and we debrief, then they finish the Incomplete. #MTBoS #iteachmath bit.ly/3YXGpW2

I am printing a noperthedron pencil holder :)

#mtbos #mathart #noperthedron
A teal noperthedron with a cylindrical hole in a drafting program with shadowing. The shape is vase-like with triangulated faces, but bulbous at the center and slanted inward at the top in bottom so that there is a band of 3 layers of shorter triangles in the middle and longer more angled-in triangles at the top and base of the vase (container).

Kid who rarely participates volunteered many answers today and came up to show work on the board.

♾️ #ITeachMath Please remember that no one makes the content here but us. Community will not be created without things to think and talk about. I may be verging on annoying but I care very much that math educators have a space to converse and grow! #MTBOS

During the last week of school, I had some students ask me if I had any coloring pages they could have. I didn't, but I did add "make mathematical coloring pages" to my to do list for this summer!

Back on Twitter, my most viewed tweet was a link to my "math pep talk"—a video I made for my students that now has 23K views 👀

m.youtube.com/watch?v=kenf...

There's a lot to expand on in that video, like structural barriers to success in math. But I'm sharing it again anyway.

The #math community seems to be growing here and becoming more active. I have presented on how to get the most of being in a community like this many times and here are my tips to grow this PLN and make it useful for educators.

Bonus Tip - Use the Feeds:
#MathChat #MTBoS #iTeachMath #MathSky
Tips to move beyond a “lurker” (and/or start to interact with the Online Math Community) Like - Who benefits: You (it acts like a bookmark) & the Poster (“Yay someone liked what I said”) Repost - Who benefits: You (it acts like a bookmark), the Poster (“Wow, they liked enough to share it”) & the rest of us (Reposting sends it back to the top of the feed increasing the chance of your followers and their followers to see it) Comment - Who benefits: You (interaction brings more friends and knowledge), the Poster (the conversation they started continues) & us (entices us to become part of the conversation too) Post - Who benefits: You (sharing thoughts and resources help to hone your own ideas) & Everyone else (the more discussion, the higher the chance we all learn) Tips for making your Posts more visible: Add an image - including a visual has been shown to increase the interaction Include hashtags (not too many) - a hashtag categorizes your Post and makes it visible to a wider audience than just your followers. Here are some math related hashtags that relate to education: #MathChat #MathsChat #MTBoS #iTeachMath #ElemMathChat #MathArt #MathSky Tag some people (not too many) - you can tag relevant people (even those who don’t follow you) in the Post or in the Image to increase the conversation potential

Math friends! I've finished (for now) getting my lectures on logic for proofwriting into booklet form: crgibbons.github.io/LogicForLine...

If you love it but also hate it, you can fork it and improve it!

Yesterday I wrote a thread about how collective action isn't just a hopey-changey platitude—it's arithmetic (mathematical topic: "Fermi problems"). I've now expanded it into a brief essay for laypeople so that anyone can understand why individual actions matter. Sharing is caring! #mtbos #iteachmath

A more balanced article from Chalkbeat on the class size law in NYC: www.chalkbeat.org/newyork/2025... #MTBoS #ITeachMath #EduSky
NYC teachers rave about smaller classes but struggle to find enough space
NYC educators say having smaller classes is “amazing,” but finding the space and funding to reach 100% compliance remains a giant puzzle.

As I finish grading my Algebra II tests, I want to tell my students that every time someone writes (x + a)^2 = x^2 + a^2, after I’ve spent DAYS using the area model, part of my heart withers away, a kitten dies, or something equally bad. I can’t take this much algebraic trauma. 😂 #MTBoS #ITeachMath

Here is a true story that just happened to me that will be *most* appreciated by any Math Twitter escapees who are here. #ITeachMath #mtbos
Y’all. I am in california. I’m weeks overdue for a haircut. I just got one and the guy asked what I did for work and I said math professor and he said “Can I ask you a question?” Im like, uhhh... “On TikTok they were saying woke lefties don’t believe that 2 + 2 = 4. Is that true?” I was like sir this is a Wendy’s.
