#Claude made me this: Type I and II Errors. It took minutes.

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

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...

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!

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)!

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.

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.

In #MathsToday my kiddo beat me at SKYJO. He's 5 and happily adding up those negatives. Today I showed him pairs that add to zero. He has been counting to -2 since he was 3 because of the lift in our apartment block...

In #MathsToday I genuinely used @geogebra.org as many times as I have posted. In this example a student was interested about what differentiation was so I knocked this together live. Turns out I randomly picked a very nice function to illustrate it. New to GeoGebra? try to recreate it!

@geogebra.org It is great when you can build on others' work. I nicked this from the University of Adelaide and made the ones and zeros S for success and F for Failure to introduce BinomDist. I am hoping students will appreciate me not asking for 5 trial trees! www.geogebra.org/classic/bzt4...

In #MathsToday we added sites to our Voronoi Diagrams. Open the link, export an image and use it as a worksheet for you #IBMaths Classes. Really makes you think about the sequence of an explanation. Not updated with easier coords and eqs to calculate.
