The Mr Barton Maths website has just had a massive update. Please share this post. @mathsjem.bsky.social @susanwhitehouse.bsky.social

Does anyone please have a list of the proofs that students need to learn for Pearson EdExcel A-Level maths? 🙏 @themathsbazaar.bsky.social @susanwhitehouse.bsky.social

Am enjoying Pythagorean Probe from @transum.bsky.social www.transum.org/Maths/Exerci... Have you tried it?

Problem of the Week 158! Please do not comment the solution so others can work it out too. Instead, like this post or comment a thumbs up if you think you have the correct answer! The solution will be posted in the comments on Thursday afternoon. #Problem #UKMT #Maths

Found at the Premier Inn. Night, night!

Today, 29th of January, is National Puzzle Day in the US. I have just counted and there are 428 free puzzles on the Transum puzzle page. The image below shows some examples. www.transum.org/Software/Puz... I hope you have a very Merry Puzzle Day and a Happy New Conundrum 🌞

We’re enjoying this from henkreuling.nl Location will be shared below.

A lot of people are finally happy to understand ’why’. Me too. youtu.be/ZocN1K_AXaA

PIN Possibilities is a new combinatorics activity in which pupils work out how many different PIN codes are possible under a range of rules and constraints. www.transum.org/Intro/?ID=546 #mathsresources #mathschat #mathstoday #mathchat

Those of you who teach the topic of circular motion in A level Further Maths Mechanics, do you use the term 'centripetal force'? It doesn't seem to be mentioned in the specifications I've looked at, though it is in A level Physics specifications. #ALevelMaths

Want a 2.5 minute primer on the ingenuity of randomised controlled trials? Of course you do.

Congratulations to Dr Chris Pritchard OBE @scottishmaths.bsky.social on the award of his OBE for services to Mathematics Education. Well deserved!

This is a maths 🆘 Please send help! In the grid, we can see exactly one multiple of 5 in each column. If I generalise the grid method for a coprime positive integer pair a and b with a<b we will have a columns and b rows. How do I prove that there is only one multiple of b in each column?

Longshot question for my network. Is anyone in Hong Kong? I am looking for a book, and one copy exists in the world, in a library in Hong Kong. search.worldcat.org/title/513774... They won't even photocopy the table of contents for me. #FindABook #iTeachMath #LostBooks

Hey all! We've got a new episode of Graph Time with Sara and Sean for you today! Sara and I were playing with some graphs and discovered a really fun way to create tons of beautiful mathematical patterns. Check out the episode: www.youtube.com/watch?v=7v0J...

Something for the weekend? A game of innies and outies.

I have two books by an author, Keh-Gong Shih, pub in 1996 that are just brilliant! But they are definitely lost. The first is PIctorial Mathematics: Patterns. It is fabulous! full of images like this. He created his own software called Mathgraf which is used to generate the images. #mathart #mtbos

An opportunity to use a ‘zero pair’ in A-Level maths @studymaths.bsky.social Lookey-likey question from @catrionaagg.bsky.social

There are a number of ways of expressing the domain of a function and hopefully they're all covered here in this new multiple-choice exercise. Choose the level consistent with your syllabus. buff.ly/DYOELZU #mathsresources #mathschat #mathstoday #mathchat

Hello @davidkbutler.bsky.social - I had the urge to create (yet another) one-player online game/puzzle based on your Digit Disguises game. I have yet to try it out with students though. www.transum.org/Maths/Puzzle... Thanks so much for all the sharing you do. Have a great weekend!

I grew up loving comics, so how am I only now discovering graphic novels? Just finished Muybridge by Guy Delisle. Brilliant. @dandq.bsky.social

Not all wrong answers are equal. I used to think students just needed the right information to fix misconceptions but then I read the work of Michelene Chi🧵⬇️

If you *were* interested, a really good thing you could do is follow me in case I announce something. Also, it would only work if a good core of enthusiastic folk from both teams engaged with it, so sharing this post would let more people know about it.

Enjoy this equilateral triangle rolling inside a square.

Here is a desmos version www.desmos.com/calculator/5...

My favorite relationship between an equilateral triangle and the horizontal distances between the roots, extrema, and inflection point of a cubic graph.

The best kind! 🧙 I lack the educational background of a mathematician, but I've studied the data behind roulette curves for many years. I have insights. I have equations. I have so many questions. Have I made discoveries and if so what should I do with them?

Have a graph idea that's outside of the box? Add variables to the definitions of your graph bounds to track a point along a curve, adjust the window using actions, keep a label in the same relative position on your screen, and more. The possibilities are boundless. #mathsky #desmos #iteachmath

If you have 5 mins and can help me with this YouTube nonsense instructions at the end of this video. It won't take long but will flag the videos to them. Appreciate retweets. If this gets resolved I can get back to making papers! www.youtube.com/watch?v=9b6z...
