Another AI Use witnessed in school: Tutor needs to write end of year form tutor reports for each tutee. Tutor leaves long vocal note to AI for each student. AI comes back with a couple of paragraphs. Copy/paste paragraphs after quick check. #MathsToday

#mathstoday #alevelmaths Ridiculous personal view below (back in my youth). Disclaimer: view does not relate to any thoughs about maths pedagogy.

Before going to bed, I will leave with the bombshell and very controversial opinion that I absolutely hate the notation df/dx for derivative of f. In my students days, I would see it as a physicist notation, unworthy (🫢) of the mathematician notation f'

The notation "fg" for composition of functions is a terrible notation... Responsible for much confusion and mistakes galore from students. Do you have your own "most hated" maths notation? Let me know #MathsToday #Alevelmaths

Is is normal to have the end of June and all of July taken out by a flurry (not just one) of trips or activities such as "fun days", in schools? #Mathstoday Too much. It might sound crazy, but I'd rather teach and finish whatever students need to finish studying.

The theorem that was taught to me, many moons ago, and is still taught today to all Year 7 students in France, called Thales theorem (proportionality in triangle) is not called Thales theorem in the UK, but the basic proportionality theorem? Is that correct? Help #MathsToday

In #MathsToday we looked at flow/depth problems with Year 9. I give you a depth/time graph and on your MWB you must sketch a corresponding 3D shape... When we spot an erroneous shape amongst the MWBs we reverse the question and class must draw a graph corresponding to that particular 3D shape.

Recently in a French bookshop: I saw the name Kolmogorov, stopped, scrolled a few pages, and quickly went to the till with this book. Maths books, 3 volumes, sixth form to early uni. Russian masters. Right up there. English version: "Mathematics: its content, method and meaning" #MathsToday

Love Maths, but not always in tune with what are commonly called "puzzles". Sometimes feel "puzzles" look down on you while I like Maths which look straight at you. Therefore am a fraud? Maybe.

Are we part of the social structure? #MathsToday

Forgot #MathsToday

Remind me again why National Exams are given by different "awarding bodies" (some private), hence giving students slightly different tests, having slighly different ways of doing things, with teachers having slighly different ways to prepare students for them...?

Why is a lot of "classic" American authors from late last century, and American litterature in general, so hard to find in bookshops in UK? A bit of McCarthy and DeLillo, that's it? Jim Harrison and Tom Wolfe might not be to everyone's taste, but 0 book in most london bookshops, really ??

I read an exchange once (can't find) between A-Level maths teachers, regarding the sequencing of Stats in the Pearsons textbooks, how it was not great and how some used a different order in practice... If that rings a bell, I d be grateful to get your opinion on it. #Alevelmaths #MathsToday

After immense pressure put on me (see picture attached, not the post quoted), I have ordered this book. It does look great. Hope it arrives at the door fast. #MathsToday #ALevelMaths

Not another textbook, just a great book about Mathematics. What do we really do when we "do" and "think" about Mathematics? I recommend without a doubt. #MathsToday

I did not know this book, apparently "an old classic". I enjoy it. Quite pleasant to open at random and read. #MathsToday

A-Level Maths related question: Is it frequent, not frequent, or in between, to give a Year 13 to a teacher who has never done a Year 12 before? #MathsToday

This seems low to me. For comparison purposes: i am in a London comprehensive, and homework is given on a popular online platform: I see/suspect much higher % #MathsToday

"Overscaffolding is a bigger issue than the lack of scaffolding" Some merits or just a provocation? #MathsToday

"97% of homework given nationally is entirely completed by AI." This is a fabricated statistic. Which might be true. #MathsToday

With Year 10, tried something for experimental probability... Gave them tables with number of tails outcomes for each of 2 coins (one biased, one fair) after a series of flips...the experiment repeated several times.

I have a small sample of observations/experience to formulate this hypothesis this but i ll do it anyway: A-Level Maths is generally being taught rushing. (?) #MathsToday

Pythagoras: The most "well known" theorem by students, even before they start learning about it. What have your tried, in your years of teaching, as an introductory lesson to Pythagoras, which work well and is not routine? #MathsToday

Forgot to #mathstoday

So I have done this lesson with a Year 9. I thought it was not too bad for a first but who am I to say... I used a similar structure to the lesson than the one used in the paper, but changed the start a bit...

Planning on stealing and trying a lesson from a Japanese teacher with some Year 9...as seen in Colin Foster's paper.. #MathsToday

Question asked on board to Year 10s: A=B C=D From this, create as many equalities as you can. Got some nice answers and some to discuss (eg can we really write sqr(A)=sqr(B) for sure?). To be fair, was already happy to see some do A+D=B+C, as opposed to just A+C=B+D. #mathstoday

Anyone has done a percentage task with chocolate bars and cocoa solids % requirements yet? Can also be extended to various regulations such as: there is a max thresold of 3 g of fat per 100g for a product to be labelled as "low fat". What is the max % of fat i can put in my product? #mathstoday

Have you ever asked one of your class (any year) the following: "What is the area of a line? What is the area of a segment?" ? #MathsToday

Was thinking of giving this to Year 10 soon to sum up what they have seen in trigonometry. Goal: Find as many ways as possible to solve. One exact solution needed. Could be turned into a more or less rigorous exercise with bounds as well. #MathsToday Improvised hashtag: #HowManyMathsWays

Hello #MathsToday, would someone know a good place to find quite challenging questions for Year 11s, and which are as remote as possible from a GCSE style question (but workable with what a year 11 should know in theory)?

Curious...i'd be interested in honest thoughts of uk teachers about how Geometry is taught in KS3/KS4 and its curriculum in those years? #mathstoday

In #MathsToday (actually last year, first year teaching), we trained with Y10 on quadratic substitution with the challenge to be the first to find a non prime number generated by special polynomials (mathworld.wolfram.com/Prime-Genera...). Drawback is not using negative integer values to substitute.

Curious. How many of your students could do the following without using "angles in polygons" type of reasoning? "On the plane, a quadrilateral has three right angles. Prove that the last angle is also 90°." #MathsToday #iTeachMaths

Challenging students to come up with some convoluted equalities after I showed them Grid Algebra (by Dave Hewitt), I wrote on the board what was dictated to me by a Year 7 student. Sorry for the squished 14. #MathsToday
