Sion, Switzerland. Sorry about the light I couldn't take a better photo unfortunately.

And this one. If memory serves me I was asking questions about shop visitors and whether it was uniform or there was some reason there were fewer on sat/sun. Both Chi GOF granted. Looking forward to others suggestions. www.geogebra.org/m/uqmkcage

On the import, what about pasting csv or markdown with latex, does that work? I'm thinking I'd work it in Claude and paste in a tool like yours. Thanks for sharing!

Take a look at this from @dalechapman.bsky.social I love seeing apps like this pop up now. Vibe coding has unlocked so many doors

Brilliant, missed this by a day as we used a similar exploration on #Geogebra. Did you make this yourself? Vibe coding has really opened a door for me; creating these things has become an easy reality.

Claude to reorder the questions. I know there could be mistakes, but the benefits outweigh the costs, and I'll work closely with the student if something doesn't match the worked solutions Claude generated. AI didn't replace me; I used it to my advantage, and I showed the student I was doing it.

Dr Jason Murphy @mathstweetcher.bsky.social · 27/01/2026

In #MathsToday, I used Claude to very quickly generate some questions with exact trig values in response to a student's question. He needed a way to practice beyond simple recall. I tweaked it a couple of times to remove supplementary angles, that is limit to 30 45 and 60, I also asked...

Looks great! Have you tried playing with LaTeX in overleaf? I've had some success with it, you might be able to make yourself a standard template and fill in the maths. If you open Claude or Gemini in an IDE, like Visual Studio, you can have some real granular control too :)

I added a display about #mathematics #books. It's a look into my bookshelf at home, but importantly, it encourages the students to read about #mathstoday... www.jmaths.xyz/posters/books/ There are many more out there I didn't include, so feel free to tell me your favourites, and I'll add them!

Composite functions anyone? I like to share this one each time I use it. Here's a dynamic version on @geogebra.org www.geogebra.org/classic/hf2k...

Dr Jason Murphy @mathstweetcher.bsky.social · 15/10/2025

I don't quite have time to do this, but I have bookmarked it because I am wondering if there is a version of this question that asks for the equation of the straight line resulting in 2 equal areas. Perhaps through the origin to make it easier. I like the whole premise, thanks for the prompt.

The claim of 30000 combinations in Cold Rock Ice Cream doesn't feel like a lot, does it? Anyone want to do the combinations for me?! I wonder where that comes from. 6CR is already 38760. #MathsToday

In #mathatoday I read @kityates.bsky.social and the kiddo was introduced to decimal numbers at the pool depth. He stood at what we assumed was 1.6m (another linear scale Kit)!

If you don't know, a plât diviseur has it's origins in Pornic, France and is intended as an aid for cutting circle cakes into uncommon divisions 5, 7, 11 etc. Traditionally the design incorporates rotational symmetry.

On LinkedIn I shared a project for our project week. Plat Diviseur. Applied mathematics at a moment of expertise, the students can measure angles and divide and therefore in year 8 they put these skills into practice (with a little about constructions too)

"wow a rectangle, hey wait a minute I can see 3 twos!" In an exaggerated surprised voice. Love this kiddo v. much, father son week while mum is away and moments like this are so special. #iteachmaths but in #mathstoday I was teaching this little man to explore...I know what I can do, he says.

Dr Jason Murphy @mathstweetcher.bsky.social · 25/06/2025

Nice! I'm thinking now about the graphs too, an image with the vertex fixed and identified then questions about a b and c (or h & l) in various forms. On my phone so can't create a quick example, but you made me think - thanks!

I appreciate the original question was directed at ALevel teachers but thought it interesting that it's fairly standard for us (I never taught it at ALevel) and thought others would be interested too.

Dr Jason Murphy @mathstweetcher.bsky.social · 19/06/2025

It's used in IB, this is a question from 2021.

He's 6, he's working on handwriting and all manner of other things in school (in a second language nonetheless) this parent perspective has contributed so much to my professional growth. I'd love learn a little more and to teach some primary maths now!

Dr Jason Murphy @mathstweetcher.bsky.social · 16/06/2025

Family fun. Sometimes I wonder if I am cheating the system. What about the kids who arrive at school who haven't played with mathematics very much? Do I contribute to a disparity and raising of an artificial bar? With time being squeezed at schools, how can we promote more of this home?

In #MathsToday we were talking about Chekhov's gun (the idea that, in a play, if a gun is introduced early on then it must be fired at some point later) The Chekhov's gun in our question was that the area of a triangle was 8. We hadn't used it yet, so we had to figure out a way to introduce it.

The equation x³ - 8x² + cx + d = 0 where c and d are real numbers, has roots α, β, γ.
When plotted on an Argand diagram, the triangle with vertices at α, β, and γ has an area of 8.
Given α = 2, find the values of c and d.
Fully justify your answer.

A little challenge in arithmetic would be to ask what would have to happen, and in how many years, for this sequence to continue.
