Some Puzzles I Made For My Students

This semester I’ve been teaching a module that covers a couple of different maths topics, and have been setting little puzzles for my students to complement what they’re learning – and some of them have been quite fun to write and play with. I thought I’d share some of them here, so you can enjoy them too.

Review: Math Games With Bad Drawings

Photograph of the book cover. It's big (did we mention that) and yellow, and covered in drawings of jokes about games.

Friend of the site and good writer/bad drawer Ben Orlin has recently released a new book, and we were kindly sent a copy to play with and review.

Mobile Numbers: Truchet Tiling

In this series of posts, Katie investigates simple mathematical concepts using the Google Sheets spreadsheet app on her phone. If you have a simple maths trick, pattern or concept you’d like to see illustrated in this series, please get in touch.

Since apparently I’m now a maven for interesting fun things built using Google Sheets, someone tagged me in to suggest I might like to see this Truchet Tiling Generator, built in Google Sheets using images generated in Google Drawing.

Mathematically Gifted

Between the three Aperiodical editors (myself, Christian Lawson-Perfect and Peter Rowlett), there’s a developing tradition of excellent mathematical gift-giving. This year, Christian has excelled himself by designing and creating a brilliant mathematical hoodie, which features a meme about an in-joke (and who can resist either a meme or an in-joke?)
