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

![An XKCD comic in the usual black outline cartoon style on a white background.
[A banner is hanging from the ceiling with a large line of text above a smaller one:]
Mathematical society
2025 meeting
[Below the banner there are four people, three of them are standing close together to the left with Hairbun leftmost addressing Cueball and Megan who is looking at her. Ponytail is standing to the far right next to a whiteboard, and is using a marker to circle in the last number on the board.]
Hairbun: Any other new developments from the year to cover before we wrap?
Cueball: Oh, the teens picked a new funny number.
Megan: Aww, I'm glad to hear they're still doing that.
Ponytail: I'll add it to the list.
[The board contains two columns of numbers, with the first having a text behind it, thus covering both columns. The last number is the new one circled in by Ponytail. From top in reading order they are:]
23 (skidoo!)

When I was on @looksunfamiliar.bsky.social I chose this sequence from a 1979 Sesame Street episode - probably the first time I ever heard Philip Glass was this exclusive piece he wrote for this animated sequence, Geometry of Circles. It's never appeared anywhere else.

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.

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.
