In this editorial, I explore what it means to teach (mathematics) in a time of polycrisis. I use Anna Tsing's argument from "The Mushroom at the End of the World" to unearth the capitalist logics that underlie much of our educational enterprise to reimagine new possibilities. #iteachmath #EduSky

Accurate 😅 (although they missed 21, which was the scourge of my early teaching career!) xkcd.com/3184/ #MathsToday

It's time for #MathStratChat! Rules: post your favorite or a clever solution! It's also fun to comment on other's strategies. Tell us about your reasoning. #MathIsFigureOutAble #MathsStratChat #MTBoS #ITeachMath #MathEd

love the structure: loose writing and figuring makes space for creative mathematics and mathematics as play challenge the content: framing mathematics in terms of monetary compensation reinforces the mathematics as competition and sorting mechanism

WHY KIDS NEED TO TALK IN MATH CLASS. Kids don’t learn math by listening to us solve problems. They learn math by talking about how THEY solve problems. Mona Iehl shares 3 tips for productive talk. #edusky #iteachmath #mtbos @monamath.bsky.social #mathed @nctm.org www.middleweb.com/52910/why-ki...

A few 👀 @catrionaagg.bsky.social geometry puzzles that definitely won't totally consume your Sunday or November or ...

From @desmos.com graph to Tinkercad to a phyical 3D printed object. My first 3D print of a Desmos project. I added a loop in Tinkercad so that I could add a string and hang it. #ITeachMath @edtechcocek.bsky.social

old rule: all updates may only be pushed out at 8 am local time. I am not interrupting my workflow to update my software at random 1:21 in the afternoon

A chess piece planned in @desmos.com, designed in Tinkercad, and printed on a 3D printer. I’m hoping to have my Calculus 12 students design their own chess pieces this year as we explore volumes of rotation. @edtechcocek.bsky.social #ITeachMath

Multiple times this week an idea from another teacher multiple time zones away has made its way into our classroom in a positive, impactful way—and I'm reminded, despite all the other stuff, that doing this work in community matters. It matters a great deal.

Treat yourself, it's not a trick! 🎃 The solutions for the October #ProblemSolving Calendar are now posted! November calendar coming soon... #iTeachMath #MTBoS #MathSky karendcampe.wordpress.com/2025/10/01/o...

Great resource for students with dyscalculia. A context dependent calculator: dyscalculator.app #disablities #iteachkids #mtbos #MathSky

Do you have a student with dyscalculia? Learn about what this condition means, and how you can help students in your classroom that have it. ➕ #MathSky #ITeachMath #SpecialEducation

How useful are for LLM's teaching proof? Check out this paper from Carnegie Mellon by Eason Chen et all arxiv.org/pdf/2509.16778 TL;DR: Improves HW but not Exams Supports low self efficacy students Would love the opportunity to play with some of these. #iteachmath #mtbos
