We're hoping to avoid any interview horror stories this Halloween 👻 We've teamed up with @brasenoseoxford.bsky.social to host 11 online interview workshops 3–17 November for anyone applying to @cam.ac.uk or @ox.ac.uk for undergraduate courses. Find out more & sign up:

Recently I was playing with the Square-Sums Puzzle (as explored previously by @standupmaths.bsky.social on Numberphile) and realised it would be fun for schools. So here is a FREE teacher resource: think-maths.co.uk/square-sums (and enjoy its use being modelled by my in-house mathematician below).

I even found a copy in that intellectual backwater that is Cambridge . @teakayb.mathstodon.xyz.ap.brid.gy

A useful thread for anyone who buys ebooks.

Drove past Cambourne. Lovely rainbow visible as we went by. Perhaps another column for the Large Data Set? #ALevelMaths #UKMathsChat #mathsky

Family member just pondered whether anyone had made an earth sandwich. Thanks to the #HoagieHomies, I was able to answer without hesitation. (Or deviation. Or repetition.)

Math[s] is just an excuse for cut-and-stick activities. #MathsToday #mathsky

They say that if you stay long enough in the Norrington Room then every author in the country will come and sign your book. Spotted in Oxford's unique bookshop - @teakayb.mathsy.space

Had a bit of time after teaching series but not wanting to start the next topic, so told my Y13 Furthers about the analogy between functions and sequences that takes differential calculus to difference calculus. Lots of fun! #MathsToday #ALevelMaths #UKMathsChat

I have an opportunity to get a new maths book. It's a book for me, not for work, so I want a maths book rather than a maths ed book. Recommendations, please, for books that taught you a bit more actual maths. #UKMathsChat #MathSky

The Oxgordshire Youth Maths Conference was fantastic - but then I would say that, so here's Helen saying it so you can believe it! #MathsToday #UKMathsChat PS if you're in a secondary school in Oxfordshire, let me know if you're interested in attending next year.

Just mistyped: "encouragement al9ng" It got underlined, with the suggested improvement: "encouragement, al9ng"

Oh dear! #ALevelMaths #UKMathsChat #ITeachMaths #mathsky

Gotta love it when Catriona plans my next lesson!

Anyone got any funky applications of the method of differences? (Further maths alevel) Asking for a friend #UKMathsChat #MathsToday #mathsky #ITeachMaths

Gets my vote for the worst (ie best) pun

The call for peer reviewers is very real - if you teach maths at the upper end of school through to early university and are interested in maths content useful to people like you, please get in touch via [email protected] - thanks! #MathsToday #UKMathsChat #ALevelMaths #MathToday #MathSky

Further Maths today: used the method of differences to prove the summation of squares formula, thus also foreshadowing MoD as a more general technique. Unfortunately, only left myself 3 minutes to do the sum of cubes. Did it in 2. #MathsToday #UKMathsChat #ALevelMaths

Recommendations for where/how to get audiobooks that are not Amazon? (or whatever other company we have decided to cancel this week) Yes I'm aware of my library but they don't have everything.

Perfect tribute today

Respect.

Craig Barton's experiments with genAI are interesting ... not that they will get me to start using it, but that they are more likely to mean I stop listening to what he has to say. Which would be a shame. (Though there's a certain irony in genAI being a gateway drug for LaTeX!) #UKMathsChat

yeah we're into LLMs (Large Lamb-bridge Models)

I'm teaching a course on Math and Democracy this year, so I've decided to debrief what we do week by week. Here's week 1: jclevelandtran.com/2025/09/16/d... #MTBoS #iTeachMath #iTeachCivics

#MathsToday Introduced the idea of a domain with a few examples and then used this. It worked well! I felt it helped them get a ‘feel’ for things rather than getting stuck in computation. I want to build in some generalisation next lesson to have any square with a vertex on the origin. 1/2

#extrapure first (virtual) lesson of the course. Short overview, some set theory basics using a visualiser, defn of binary operations. On to modular arithmetic. Chat blast questions work nicely to set the pace. I will try to post each week with a summary. #alevelmaths

Picard's theorem (not, not *that* Picard): an object in a free-flowing river has no free will. #MathSky #UKMathsChat #ITeachMaths

Stealing. #MathSky #UKMathsChat #ITeachMaths

Since the date is a bit triangular, it seems like a day to repost some of my ruminations on lengths and right-angled triangles. #MathsToday #MathSky #UKMathsChat #ITeachMaths

Awesome!

I popped into a maths workshop yesterday because I saw some people I recognise through the window. At one point the tutor said to a student: “Are you seriously using ChatGPT right now, when I, your human tutor who can answer your questions, am right here?!”

Math[s] friends! I have learnt of the travesty that is varpi. I have seen it and can only bear the knowledge of its existence by inflicting it on everyone else, so here it is: ϖ Naturally, I have questions. #MathSky #MathsToday #ITeachMaths #HoagieHomies

Books I would like to write: 1. Too many solutions by Andrew Stacey with not enough diagrams by Catriona Agg 2. What I wish I'd taught in Maths

New! My 192nd gems post. Ideas, updates and resources for maths teachers. 💎 www.resourceaholic.com/2025/09/5-ma... Hat tips to follow. #mathstoday #ukmathschat #alevelmaths #iteachmath

My favourite thing about the maths teacher community on Bluesky is #MathsToday. If you’ve not joined in before, I can really recommend it. Posting a highlight of your day is very uplifting! I’ve kept forgetting this term, though, so going to attempt a week’s worth in one go…

I have put a mince pie in my lunch for tomorrow and I don't care who knows.

NEW BLOG: The Wizard of AI www.emaths.co.uk/blog/general...

Cool paper out by mathematicians studying population dynamics with algebraic geometry @georgysch.bsky.social @mpi-cbg.de @csbdresden.bsky.social @math-mpicbg.bsky.social

Holding a Clubs/Societies/Enrichment Fair for your school or college? The National Cipher Challenge might be just what you need. Here is a poster you can use to promote it! The site will open for registration on Sept 18th and the competition starts Oct 9th. Challenges weekly throughout term!

Today at #TMiP25, I'm at @TeaKayB#tmip25s session on maths in museums. (You should hire him.)

This just flew past me on some sort of aggregation list. Anyone listening to @sparksmaths.bsky.social yesterday at #TMiP25 might find it eerily familiar! theconversation.com/despite-a-le...

Alas, poor Rupert! #UKMathsChat #mathsky

I have been doing Paddy's problem solving questions every day this summer, and I have found a lot of them challenging. As well as enjoying them very much, they have helped me focus on how I teach problem-solving. Here are the top five things that I have come away with. #ALevelMaths

Feels more like a channel 4 program than bbc, but good to see that the water companies are trying different things to clean up their pipes.

#CoreMaths? Definitely #UKMathsChat Is there a UK version of the report card?
