@ColinTheMathmo Wow! Who knew there was so much to juggling patterns! We loved your talk today. Thank you! Can’t recommend @MathsInspiratn enough - if you get the chance, please go!

Here’s a little bit of another great ⁦@MathsInspiratn⁩ show. Well done ⁦@robeastaway⁩ ⁦@StatsJen⁩ ⁦@Aoife_Hunt⁩ ⁦@ColinTheMathmo⁩ Teachers, if we’ve got a show near you soon then get your students invovled too! https://t.co/QuuHCl6wQe

Excited to be back in Leeds with @MathsInspiratn at the Leeds Playhouse for some real-life in-person talks. Talks from @StatsJen, @ColinTheMathmo, @robeastaway and @Aoife_Hunt.

The inspiration for this week's @puzzleoftheweek came from the brilliant @nrichmaths game 'American Billions'. @alisonkiddle and Charlie made a great video about it for @mathsweekldn. Divisibility tests, strategic thinking and creativity all in one.

Blame my friend Paula for how ridiculous this puzzle sounds. I wrote the problem and then promised her she could choose any theme she wanted...

The answer to last week's puzzle was 72, well done to everyone who submitted a correct answer! See the attached solution explainer for more details. #puzzleoftheweek #puzzletime #mathematics #funwithmaths #maths #schoolscompetition

It was a pleasure to deliver a remote talk to 400 students from @KocSchool in Turkey today. We discussed creativity in maths and creating your own questions. Hopefully I'll be able to use some of their students' questions for @puzzleoftheweek next year!

I made these diagrams manually for a puzzle I wrote recently. Can anyone recommend some software for drawing solids that would do this quickly? Is @geogebra my best bet?

Happy pi-day everyone! As beautiful as pi may be I deliberately never use it in https://t.co/SYCjKA6kCr puzzles to limit required curriculum knowledge. There's still some interesting geometry in this week's puzzle though...

There's over 120 free puzzles in the Puzzle Library. I've spent a lot of time over the past 6 years writing detailed solutions with extensions and further reading. It's a great problem solving resource for teachers or anyone who likes solving puzzles.

So I was playing tennis with four friends and had to sit out for a few games. Obviously I wrote a maths puzzle about it.

Happy Monday! It's #puzzletime Here is this week's puzzle for you, please submit your answers by Sunday at https://t.co/GPRIBZ1o9p or use the QR code. Good Luck and enjoy! #puzzleoftheweek #mondaymaths #funwithmaths #puzzles #mathpuzzles #mathematics #mondaymotivation

Oh, and follow @puzzleoftheweek for the new puzzle each week and competition updates! Thank's so much to the amazing volunteers @missdicksonmath and Vicky Bould who run the social media and do the majority of the weekly competition admin.

The Puzzle Library is also up and running again. I'm very proud to share these 125 problem solving questions and their full solutions on the site for FREE.

Many of you know I've run a free puzzle competition for schools for the last 6 years. I was late getting started this year, but https://t.co/SYCjKA6kCr is up and running again. It's been great writing puzzles again and seeing an enthusiastic response.

This diagram forms part of a puzzle I was writing today. On its own I think the image is dying for questions to be asked about it.

Hello Twitter, it's been 2 years. I've been hibernating, waiting for the world to become a little more accommodating for freelance maths educators. Speaking to @alisonkiddle, @FranMaths, @jamesgrime and @AJMagicMessage recently though, it seems to be getting better out there...

Good morning everyone, Puzzle is 125 attached below. Best of luck with it! If your school has registered, you can submit your answer online at the home of Puzzle of the Week https://t.co/GPRIBZiZxZ or using the direct entry form link https://t.co/e99AgScN5N

I really enjoyed writing this. Logic and number puzzles are my favourite. It's not simple though, can you solve it? All @puzzleoftheweek puzzles are completely free and if you register (for free) your school can compete against over 300 other schools around the world!
