But circle theorems rock! The musicians and poets should definitely study them.

1T indicates that Wales have scored 1 try. This is not necessary, because the only way to score 7 pts is via a try. What is the smallest ambiguous rugby (union) score? The biggest unambiguous one? [Try = 5pts, Conversion (only following a try) = 2pts, Penalty/drop-goal = 3pts] #MathsToday

Still reeling after the theme tune from The Bill was changed from the iconic 7/4 original. Now this.

Just seen the Liechtenstein national anthem. Surprising tune!

How awful is that formatting?

Genuinely one of my proudest moments. bsky.app/profile/catr...

I blame @catrionaagg.bsky.social !

Disappointing that BBC Sport didn't put "(TEN)" after the Man City score.

I've just signed up for this. 5 twilights (Zoom) and a course day (travel and cover are funded). AMSP courses have a tradition of being superb. What's not to like! #MathsToday

Come for the maths and stay for the ethical discussions. :)

Have spent far too long thinking about this. Don't know if I like it or not! (Far too many 'thirds' knocking about ... )

Article about a planned sculpture (near Coleshill). Fails to mention that it’s a Möbius band. news.sky.com/story/mother...

Best thing I've seen this year. Just brilliant.

Interesting graph showing a massive disconnect between median and mean averages. The median is about 0.4 drinks per week, whereas the mean is 9.8 drinks per week.

I am old enough to remember when the first couple of Google results were all you ever needed. Now you get this...

Many congratulations to @bobbyseagull.bsky.social on his MBE! To see someone who so freely gives of their time to support important educational causes being recognised in this way is really positive.

I agree. It's maybe easy for me to say as a long-time atheist, but I think in the UK there are two Christmasses that sit side-by-side. There's the religious Christmas, with all the church and nativity imagery, then there's secular Christmas which is basically a celebration of family and friends.

How's your day?

News story in the Times that says every secondary school will have to offer triple sciences at GCSE (though not all pupils will have to do them). One of the images used to illustrate the story? The usual sort of nonsense...

This is very good.

Half marathon in Surrey today. 'The Hurt' was well named (not used to all the hills). But lots of fun.

In #MathsToday I made 40 A Level teachers colour in representations of the binomial distribution. This is your regular reminder that if you teach #ALevelMaths you should definitely try to join your local Maths Hub’s A Level Pedagogy group. There is some brilliant stuff going on all over England.

In #MathsToday (in fact, #MathsRightNow at the #RyderCup ), the official website shows the state of play and also gives predicted percentages for each possible result in each match. Any comments on the predictions?

If you *were* interested, a really good thing you could do is follow me in case I announce something. Also, it would only work if a good core of enthusiastic folk from both teams engaged with it, so sharing this post would let more people know about it.

@teachertapp.bsky.social sent me this. Scary to realise hope much time I have spent on the app. There are 1440 mins in a day. So if I have spent a minute each day Tapping then that's more than a full day in total. (Not that this realisation will make me stop, obvs!)

The @telegraphnews.bsky.social keeps using this graph showing private school fee increases. According to their figures, from 1986 to 2024 (ignoring the 2025 increase) school fees have multiplied by 9.6 (so fees of £3000 in 1986 would be 3000 x 9.6 = £28,000 in 2024). /1

This is key. It would have been possible just to copy down the answers from the back of the book. Did pupils do that? Maybe some of them did. At A-level there was certainly no point, because students (should) want to understand and (should) realise that copying the answers doesn't help with that.

It was very useful to see this on BlueSky. This email was rejected by the spam filter on the school email system. I have now had messages from ATM unblocked, so will receive messages immediately in future. (And I managed to get hold of this one too.) I hope that hasn't happened to other members.

New blog on the @cambridgemathshub.bsky.social website. Might be of interest to primary and secondary maths teachers. #mathstoday www.cambridgemathshub.org/post/how-to-...

Great to hear!

Hey #CoreMaths teachers. I have updated the "What the Graph" website with 7 new graphs (I have used them in #MathsToday over the past term!) whatthegraph.weebly.com

Very lovely #CambridgeHalfMarathon today. A great run in the sun!

You're right, it seems it's not in the database, even in some shifted form. The next couple of terms are 14741, 74801. (Thanks to online Chinese Remainder Theorem calculators.)

i put the first few (?) terms in OEIS and there are no results! i may've made an error: oeis.org/search?q=1%2...

Hey #CoreMaths types. Did you see this yesterday?

Not a huge fan of Giles Coren but this is top notch satire

New blog - for #CoreMaths teachers in particular. A couple of cool Excel features that I am finding helpful at the moment. www.cambridgemathshub.co.uk/post/excel-l... (And I guess this is my #MathsToday too!) @coremathscat.bsky.social

Very powerful thread.

#MathsToday featured an argument (discussion!) with colleagues about whether the modal class of a histogram is the class with largest frequency or the class with the greatest freq density (the highest bar on the histogram). Would love confirmation from someone statsy, please!

Just realised I have a 5-year streak on @teachertapp.bsky.social !

I somehow understood none of this, and also all of it 🤣 Brilliant!

Hey #UKMathsChat -3² = ??

100% agree. It might be useful for turning scribbled thoughts into sentences - but that speaks to the obsession with documenting, not to effective lesson planning.

Description in the #AltText

Looks like the radius is about 2.5. Square that times π, and round down because it's more hexagon than circle to get 19.

How did you count the frying tomatoes? #MathsToday
