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 #mathstoday on holiday I can't type!

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)!

Hard to contribute to such a great list, tha la for kicking it off. Here's one I'd add:

Here is a link to the slides if you're interested.

I do share this every year, but I like it and of you can find the time it's lovely! #iteachmath and #mathstoday

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.

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!

Wow. He's trying to draw arrays in the mirror. 😍 #mathstoday

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.

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!

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?

That is beautifully formatted!

2 or 3 left internationally, back towards mid and end of August though.

DrFrost Maths, should be available free as a charity to a scenario such as yours.

!= As in not equal to zero. I believe.

Interesting graph, so many questions.

Very pleased to be presenting at this! I'll be talking about the wonderful world of generating functions.

He said, giggling:

"I know it's 50, we don't say 5 - 2, that would be silly. We say fifty two"

In #mathstoday. When he's up for it it's the most special thing watching him learn. (My son at home)

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.

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.

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

How Liverpool's title win has completed a mysterious Fibonacci sequence Liverpool FC's victory at the weekend has produced a strange series of numbers in the league's record books.

BBC covered it too:

Still learning the rules, he keeps beating me hands down so I don't get near the negatives!

It was perfect for my class this week so o appreciated it. Look forward to seeing what you come up with.

This was a fantastic build, thanks for making it @sparksmaths.bsky.social
