It seems that @casiojapan.bsky.social have changed their calculator again, just when we'd almost got used to the new one, and loads of kids have them. Now there is another different model to deal with - apparently the S-D key is back! Not fair.

Big Q: my HoD is worried that given the #edexcel grade boundary hike last yr (esp at G6) more schs might put more kids in for F rather than H, and this will hike grade boundaries yet again. He is considering moving to #AQA. I know it should be fair, but poss isn’t? Thoughts please! #mathstoday

In #mathstoday I’ve been desperately trying to find some short videos I remember on the maths needed in various careers, aimed at KS3/4 (rather than A Level which I can find on AMSP
@meimaths.bsky.social ) I’m sure one featured Grove Lodge Vets in Brighton. Any ideas anyone pls? Or similar?

In #mathstoday I discovered that the @cambridgeocr.bsky.social Add Maths FSMQ and paper 2 of @aqaeducation.bsky.social L2 Further Maths are both pm of June 15th, with Physics GCSE in the morning. Now I know not many candidates will sit both but surely there will be some? Seems like poor planning!

In #mathstoday my further mathematicians told me it was their favourite A Level as "it makes us realise how everything links up" 😁😁 #ALevelMaths

In #ALevelMaths today we looked at why inverse matrices work, which I am very happy about. I haven’t taught this before and was getting cross at the seemingly random stuff to learn! I didn’t do matrices until my degree and that was a loooong time ago. #MathsToday

I read a great blog the other day, presumably recent as I found it through a weekly digest. It talked about breaking down tricky topics and used the hormones in the menstrual cycle as an example. Now I can't find it - any ideas please? My son is studying this and there was a great diagram! Thnx

#ALevelMaths please get involved in helping to produce some A-Level transition matrices for AQA A-Level maths.
Thanks to those who have sent data already. To hopefully make it easier to submit your prior attainment and @aqaeducation.bsky.social Maths A-Level Grade please use the file linked here: www.dropbox.com/scl/fi/pdqqh... DM me for instructions on when to send it. Hoping to share beginning of November.

@mathsjem.bsky.social just reading your latest blog and I do sympathise with your stance on graphical calcs at A Level. We changed to @numworks.bsky.social and a benefit is it has a free identical phone app, so you could just have a school set to lend out for exams to save them buying?

#ALevelMaths question please
Mod graphs
I know they need to sketch y = mod(2x+3)
Do they still also need to do y= 2mod(x)+3? Used to be in C3 but very vague in pure 2 textbook, can't see any questions like the latter? Thanks
