I made a starter pack for KS5 maths (teachers, posters, and other people involved in it)
Most of the starter packs I've seen for maths teachers have been for all age groups, so this one is aimed towards sixth form (16-19 ish)
Please let me know if you'd like adding (or removing)!

In #MathsToday I realised I had made an error when planning out the (very tight on time) scheme of work for further maths, and I actually have a WHOLE EXTRA WEEK of lessons before the AS exam in May. I'm giddy with the prospect of what extra revision activities I might do 🤩🤣

Introducing the Euler step by step method for differential equations with my further maths students tomorrow, so it's time to show them the clip from Hidden Figures where Katherine Johnson uses it to find the trajectory of a space capsule 😃🚀 youtu.be/v-pbGAts_Fg?... #MathsToday #ALevelMaths

In #mathstoday, I motivated z-scores by asking who was faster - Michael Phelps or Usain Bolt?
In past years, I had done this after introducing z-scores, but starting with the question prompted great discussion:
"You can't compare them. They're different sports."

It's been a while since I shared this, but if anyone has recently joined Bluesky and is looking for people to follow who teach/post about A Level Maths (and post-16 Maths education), you might find this useful:

I've just noticed the point about using number keys for shortcuts - YASSSSS 🙌 This is one of the other functions I missed from the old fx-991.

Does anyone have experience of doing both AQA and Edexcel entry level? What are the main differences? Is there a preference?

In #MathsToday my year 2 #ALevelMaths further maths students were doing improper integrals. They had *a lot* of questions about why some integrals converge and others diverge, which made for really interesting conversation, but also made my head hurt on the first day back after the holiday 😅😵💫

I once made polite small talk with a woman whilst standing at the bar in the interval at a gig. As I walked away, I heard her daughter ask her who I was, and it turned out the woman knew me from a college open event the previous week (so I thought I was speaking to a stranger, but she wasn't!)
Please quote this with stories of your minor interactions with non-celebrities, e.g. “I once accidentally bumped into a man in the Wellingborough branch of Holland & Barrett”

I am not sure I’ll get the same traction here as I did on the dark place but please answer and REPOST and let’s try to build a lovely bookish thread.
The best book you read this year was…
Mine undoubtedly The Elements by John Boyne (please check trigger warnings first).

After rewatching Home Alone, Luis Batalha couldn’t stop wondering:
how plausible is the oversleep that leaves Kevin behind?
So he wrote a tiny paper and ran the numbers.

[A banner is hanging from the ceiling with a large line of text above a smaller one:]
Mathematical society
2025 meeting
[Below the banner there are four people, three of them are standing close together to the left with Hairbun leftmost addressing Cueball and Megan who is looking at her. Ponytail is standing to the far right next to a whiteboard, and is using a marker to circle in the last number on the board.]
Hairbun: Any other new developments from the year to cover before we wrap?
Cueball: Oh, the teens picked a new funny number.
Megan: Aww, I'm glad to hear they're still doing that.
Ponytail: I'll add it to the list.
[The board contains two columns of numbers, with the first having a text behind it, thus covering both columns. The last number is the new one circled in by Ponytail. From top in reading order they are:]
23 (skidoo!)

Love this 😅
Bored over the festive season? We're still seeking contributions to our ridiculous saytheprime.com video project: sign up and make a 5-minute video of yourself saying a chunk of digits of the largest known prime number. Can we finish before they discover a bigger one? It's a race against maths!
Say the Prime
We're attempting to get a collection of humans to say every digit of the newly-discovered (and currently largest-known prime number) Mersenne prime M136279841, and hope to achieve this before another…

Oh, there's my further maths starter for the first day back 🙌 #MathsToday
a lot of people are aware that you can factor
2025 = 45²
i'm honored to announce the factorization
2026 = (45-i)(45+i)
2025 = 45²
