I see this all the time with maths. People who were naturally good at school maths often fall over completely at university because they donโ€™t know how to make sense of things that are difficult to them.

Thanks for this thread, really helpful

But as an aside, may the large data set burn in hell, the worst conceived most ill judged addition to any maths qualification, an absolute nonsense waste of time.

nice!

I think a pity here is that the derivative of tan is in our formula books, so it becomes the empirical result rather than one of the ways of displaying the results.

see also differentiating tan to get secยฒ, why we don't use d/dx(tan x)=1+tanยฒx confuses me as it is a lot more aesthetically pleasing

Hmmmm, the sum of the first n squares being (1/24)(2n)(2n+1)(2n+2) is a lot prettier

talking to #alevelmaths teaching colleagues across the region we think there has been a drop off in Ss asking for help from teachers, suspect they turn to AI instead

just some gentle pushback on this, although I am uneasy too. Is this black and white? 15 years ago we broadcast felix baumgartner free falling from space? is that acceptable? F1 has become a lot safer but it is still extremely dangerous. What should the limit be?

You probably want to work in Ashby.

It's lovely out there, and @blatherwicksam.bsky.social is alright too.

soup is the most simple contender here. I tend to make less stock in the summer because most of it goes into soup.

I would highly recommend working with your local maths hub if you haven't done so yet. Great networking opportunities, high quality resources, free to attend (and paid cover!). Great CPD. Also good for personal development if you want to get involved leading

First. The booklets are entirely the teacher's work copied down.

I use them for certain topics (transformations, vectors, some angles stuff), but in general no, because I find my teaching is more adaptive to needs of students at those key stages

13.01.2026 18:56 โ€” ๐Ÿ‘ 4    ๐Ÿ” 0    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 0

We use them for A level. Huge gains on where we were before it.

We get a big sparx completion rate dip after holidays. Has anyone got any strategies they'd share for attacking this? #mathschat #ukmathschat #ukedchat
