As an etymology nerd, I was excited to just read that: frustum and bruise share the same root; there is a diminutive, frustulum; and, 2000 years ago, there was a play on words with frust[r]a! latin.stackexchange.com/questions/10...
Another bit of AI coding this morning. This one for visualising Normal approx of a Binomial distribution. I like being able to specify exactly how I want it to function rather than making do and clunking around with pre-existing stuff. I just don't have a convenient place for public sharing 🫤
It garbled the labels (of course) but ChatGPT reimagined this as a slippery-slope-into-manure of attendance
Latter half looks like this
I jumped on the AI coding bandwagon this afternoon and have a working hypothesis test 'fill in the blanks' activity. @themathsbazaar.bsky.social will be devastated to hear it looks at critical regions :)
Do you have a doc you could share? Perfect timing for my Y12s!
Bathroom, EV charger and gas meter fitters all booked in for us today. Busy house!
It seems like ChatGPT is happy to check questions/solutions from the JSON format!
No worries! If I can do anything to help then let me know. I've got coding experience
Nonetheless a really useful resource! Using it a lot with my Y13s these days, especially the 4 question do nows
I wish I'd kept a screenshot of the question, but there was a Y12 binomial 'find the coefficient of...' that didn't show the correct answer. Also on a worksheet, Q13 didn't have a change of sign and Q15 had a sign error in show that answer (it had minus, not +)
Stuck indoors on a rainy Saturday? Why not pop in an application to come and see what Hurtwood is all about!? Closing date is this Friday. (And then I'll stop re-posting this 😆)
Just from your drawing!
But I love a critical region!
These are great 'interactivities'! Just a little glitch on this one. It's complaining about 65 but it's 81 that's in the wrong position!
It began with noticing how each ‘drop’ affects the score. Moving an area of 1 down decreases the total by 2. So total decrease = 2 * area of iceberg. Then seeing that we can work with each decrease, designing the iceberg from the bottom up. And shape of each ’layer’ doesn’t matter, just its area
Sure, I get that. But then imho the N-approx should be in the Bin chapter anyway (or not actually on the course at all, as with modern calcs it's pretty redundant at A level!)
We started the Normal Distribution today, too! It's got me thinking about whether to do Bin or Norm first in future.. there's much less faff with the normal
This exemplifies the algorithm I have in mind, but it generates a less exciting shape than your illustration!
I think the sum of the |differences| must be 2n| but given that it should always be possible?
Got the Sunday evening blues? Come and join my team and look forward to Mondays! A level focussed, free meals, no Saturday school, decent holidays.. what’s not to like?!
Totally agree! I like to use this warm-up just before starting the topic. We compare the different possible approaches to the final two
A friend of mine has just launched this website that I think is pretty great for generating quick starters for A-Level maths and he has started adding some questions for Further Maths too.

#MathsToday #ALevelMaths
Perfect timing as a warm-up with my Y12 Further Maths class! Thanks for sharing
No Saturday school at all. Not even any parents evenings! Each class has a lesson every day for approx 70 mins. FM students get two of those lessons per day, two different teachers
Come and join my department! We're in the Surrey hills (commutable from Guildford, Dorking, Horsham and beyond). Looking for another mathematician to grow our team. Small classes, mostly A level Maths / FM, ice cream on tap.. what's not to like?! www.tes.com/jobs/vacancy...
In #MathsToday I invented the ‘approximately implies’ sign for small angles in trig.
Madness. We have MFA now but not needed if we’re on a school desktop. Don’t know if Arbor can do similar?
We start with CPA in Y12, then in Y13 I think we follow the textbook sequence for the rest. One of my colleagues has done it for a few years and been examiner too, so DM me if you'd like to swap contact details!
These are great!!
