Look at this, from @jonny-griffiths.bsky.social Mr Tessacadabra - a story for Maths students! colleenyoung.org/2026/10/19/m...

I've now added questions, solutions and videos for Year 1 mechanics to my site to add to the statistics already there. All 98 exam style questions are original but obviously based on past exam questions. www.1stclassmaths.com/alevelrevision

AI Overview: The Collatz sequence starting at 334 takes 68 steps to reach 1. Is there anything else that I should notice?

It's back to school this week for many, so this is your annual reminder about draustinmaths.com. There are now over 1200 free maths resources, including over 100 resources for A-level Maths and Further Maths. And when you've exhausted all of those, there are a few paid-for resources too!

Some holiday maths 🙂

One of the things I want to improve with as an #ALevelMaths teacher is my knowledge of #physics in order to teach mechanics without just saying "it's magic, right?!" Any recommendations of introductory books/texts for this?

We have absolutely loved having Ayliean speaking at our events - both for students and adults. Strong recommendation from me 😍

Great news! I've finished creating the Emerald 5-a-day for KS1 🟢🎉 corbettmathsprimary.com/5-a-day/ Answers (and proof-reading) will be completed tomorrow ✅ In addition to Ruby ♦️ and Emerald 🟢 I'll make sure that Diamond 💎 will be added by the end of August. I hope you find these useful 😀

If you are having trouble with the May Puzzle of the Month, I have produced this interactive version to help you. There is also an opportunity to extend the puzzle and turn it into an investigation, so pull up a chair at the circular table and have a go. www.transum.org/Maths/Invest...

In "broken calculator" style, find angle x, but your sin button is bust. Tried a few of these types of questions with Y10 earlier this week. #MathsToday

Hang the treasure sacks on the balance beam. The objective is to get the beam to balance (multiplying weights by distances). Mental Maths and problem solving. Have a look: www.transum.org/Intro/?ID=1169 #mathsresources #mathschat #mathstoday #mathchat

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

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!

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...

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
