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).

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.

If there were such a thing as an email discussion group aimed at giving #history #teachers and #maths teachers (mainly secondary) somewhere to discuss the history of maths and the maths of history with a view to exploring each subject in the other's lessons...

@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).

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.

And then we flicked to the back of the book and marked our own.

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.

#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!

I don't speak German, and neither do my calculus students, but even so I think this is one of the best explanations of the derivative of sine and cosine I've ever seen.
