Stuart @sxpmaths.bsky.social · 8hJust spotted this AQA question (AS 2020) - nice tying together of skills 161
Stuart @sxpmaths.bsky.social · 29/09/2026To help a couple of students who have joined us for Y13, I've had to pick out exactly how much of the Year 2 content we actually cover in Y12. 010
Stuart @sxpmaths.bsky.social · 25/09/2026In bonus #MathsToday I worked with a student preparing for TMUA - looking at 2023 Paper 2 questions on necessary / sufficient conditions in many contexts, plus advice on how not to be intimidated in questions like this one. Great fun! 151
Stuart @sxpmaths.bsky.social · 21/09/2026Sometimes two wrongs do make a right.. just marking some work where a student has replaced sin²x with (1-cos x)² and then expanded that to 1-cos²x 2110
Stuart @sxpmaths.bsky.social · 17/09/2026So, normal autumn/winter weather then... www.bbc.co.uk/weather/arti...bbc.co.ukUK weather: At least seven months of relentless rain needed to end drought in EnglandAlmost 75% of England remains in drought following an exceptionally dry spring and summer. 000
Stuart @sxpmaths.bsky.social · 16/09/2026It would be hilarious if there was a mass influx of people seeking asylum in the 'principality of Piddington' www.bbc.co.uk/news/article...bbc.co.ukPiddington in Oxfordshire votes to leave UK over asylum plansPiddington residents vote over proposals to house up to 1,256 male asylum seekers nearby. 010
Stuart @sxpmaths.bsky.social · 09/09/2026In #MathsToday, my year 13 #ALevelMaths tackled @draustinmaths.com match up activity for arc length and perimeter in radians. Nice little mix of problems to solve www.draustinmaths.com/a-level 071
Stuart @sxpmaths.bsky.social · 31/07/2026If you want to purchase Argos, the code is 786/3594 www.bbc.co.uk/news/article...bbc.co.ukSainsbury's agrees to sell Argos for £120mUnder the terms of the deal, Argos will still operate in Sainsbury's shops, sell Habitat products, and offer Nectar points. 041
Stuart @sxpmaths.bsky.social · 18/07/2026I don’t want to brag, but I’m pretty sure I could run a mile in under 27 years too 061
Stuart @sxpmaths.bsky.social · 02/07/2026Having a department clear-out and there are a lot of old books that we need to dispose of. Free to good homes if anyone is interested in any of them! (I can't deal with postage sorry, so would have to be Surrey, West Sussex or Portsmouth area to do a hand-over) 324
Stuart @sxpmaths.bsky.social · 30/06/2026For anyone interested, I've uploaded one of our booklets for sharing (Unit 1 : Points and Lines) but this is still a work in progress to some extent! sxpmaths.wordpress.com/wp-content/u...sxpmaths.wordpress.com 0145
Stuart @sxpmaths.bsky.social · 24/06/2026The more you stare at this, the worse it gets. Going to ask students how many faults they can find with it! 5295
Stuart @sxpmaths.bsky.social · 22/06/2026In #MathsToday we used some of "Tyler Tutoring"'s TMUA preparation materials. I chose the pack themed around circles (second half of Coordinate Geometry Worksheet 3). A good mix of problems www.tylertutoring.com/tmuatylertutoring.comTMUA | Tyler Tutoring 0172
Stuart @sxpmaths.bsky.social · 18/06/2026A bit of a mixed reaction to Edexcel Paper 3 from ours, but relief all round that they are done with all their exams! 320
Stuart @sxpmaths.bsky.social · 09/06/2026In #MathsToday we're having fun with proof by induction. Towers of Hanoi (interactive here: towersofhanoi.info/Play.aspx) plus this interactive version of the L-tiling problem I vibe-coded this morning: ukr-reader.github.io/MathsApps/l_... 1123
Stuart @sxpmaths.bsky.social · 20/05/2026Not sure I’d trust a language learning app that says I can “Ecome ukannian excerient”... 010
Stuart @sxpmaths.bsky.social · 15/05/2026Another Ukrainian NMT question, in a similar vein to the last one I shared. Find the largest value of a such that the equation has a root. 211
Stuart @sxpmaths.bsky.social · 14/05/2026Just put together my 'warm up' question for Y13 #MathsTomorrow 1142
Stuart @sxpmaths.bsky.social · 14/05/2026"Find the largest value of a such that this equation has no real roots." [With the war, Ukraine has moved to online school-leaving exams and this is a question from a Maths practice paper. It was multiple choice but I've only taken a screenshot of the question.] 221
Stuart @sxpmaths.bsky.social · 11/05/2026In #ALevelMaths #Mathstoday we looked at when a cardioid isn't a cardioid and if it has a 'dimple'. A lot to show in one file, but in case it's useful to anyone else here's a Desmos sheet with constant slider www.desmos.com/calculator/d... 1145
Stuart @sxpmaths.bsky.social · 28/04/2026In #MathsToday I did my favourite proof by contradiction lesson, using green and red balloons and a pin. Also focussed much more this time around on examples of negations and contradictions before diving into proofs. #ALeveLMaths 3110
Stuart @sxpmaths.bsky.social · 26/03/2026I've finally put together a blog about all the changes I've been making to the sequence in which we teach A Level Maths. Let me know if you have any thoughts or questions! sxpmaths.wordpress.com/2026/03/26/a... @tickyvanner.bsky.social @runningstitch314.bsky.socialsxpmaths.wordpress.comA Level ReshuffleLast summer, some of my long-standing frustrations with a few of factors finally led me to begin restructuring our A Level Maths scheme of work. In particular: Starting with Chapter 1 of the Year 1… 4257
Stuart @sxpmaths.bsky.social · 13/03/2026Some crazy cobwebs in iteration with kx(1-x). All these are now shared at: ukr-reader.github.io/MathsApps/ 040
Stuart @sxpmaths.bsky.social · 13/03/2026Basins of attraction for Newton-Raphson on a cubic. I'll try and remember how github works as a place to share these 021
Stuart @sxpmaths.bsky.social · 10/03/2026And one for the trapezium rule. I'm at the stage now where I can type in a carefully phrased one-paragraph prompt and trust it to come up with the goods! 011
Stuart @sxpmaths.bsky.social · 05/03/2026Another 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 🫤 061
Stuart @sxpmaths.bsky.social · 26/02/2026I 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 :) 120
Stuart @sxpmaths.bsky.social · 07/02/2026Stuck 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 😆) 020
Stuart @sxpmaths.bsky.social · 01/02/2026Got 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?! 030

Stuart @sxpmaths.bsky.social · 23/09/2025@draustinmaths.com Thank you for generously sharing all your resources - your site was my first thought when students needed more practice on building up sketches of quadratics! 041
Stuart @sxpmaths.bsky.social · 08/09/2025I’m kinda curious what happens as this number gets bigger. Will it start using standard form? A couple more emails today will get me to 5 digits 130

Stuart @sxpmaths.bsky.social · 14/07/2025I’ve got an oldish Macbook Air that won’t update to whatever random name MacOS has now. This would be fine except half the appa (including Office) have updated themselves just to be able to tell me they can no longer run! Why couldn’t they just stop updating after the last functioning version?! 😭 000
Stuart @sxpmaths.bsky.social · 19/06/2025After watching Snow White last night, I’m now welcoming woodland critters into my lessons 🐿️ 000
Stuart @sxpmaths.bsky.social · 15/06/2025Is anyone else having issues with ActiveLearn textbooks today? We’re getting an error message about ‘account not being set up’ 220
Stuart @sxpmaths.bsky.social · 05/06/2025A bit more detail on my shake-up of Y12 Maths. We're going to begin with coordinates and lines. Surds will arise naturally from Pythagoras. Rationalising denoms (not quite so naturally) from gradients between two points. First taste of modelling and stats, too. Even vectors get a look-in 2130
Stuart @sxpmaths.bsky.social · 28/05/2025Just been reading about George E P Box - interesting back story from the Army in WWII to a career in statistics. Notable quotes: "All models are wrong, but some are useful" and "Statisticians, like artists, have the bad habit of falling in love with their models." 😄 010
Reposted by StuartHannah @neechmaths.bsky.social · 22/05/2025These look like a great resource for A level maths: www.alphaworkbooks.co.uk They are closing down, so his books are currently free to download from his website until the website closes. #Alevelmaths 35020
Stuart @sxpmaths.bsky.social · 22/05/2025I'm new in town, so hopefully can rebuild my A level Maths network here. I might do a series of posts about my plans for reorganising our Y12 scheme of work... Step 1: post-its! I'd love to hear if anyone has made interesting choices in their sequencing of topics 11238
