...quite literally – or up. There’s lots of maths-prompting above and below us. Here is a picture from the Royal Academy Summer Exhibition and it wasn’t even for sale, simply the grille on the radiator on the floor. What’s the proportion that’s metal and what’s the proportion that’s hole, I am wondering. What could pupils estimate from this image?
Here’s a sight spotted from the huge queue at Stansted Airport. It's part of the roof. Many triangle questions come to mind!
Here’s something tweeted by @NCETMsecondary in August, as he walked past a construction hoarding in central London, on which was printed a Penrose tiling design:
This month the American Mathematical Society includes a feature on Penrose tilings such as this, and their many symmetries despite being non-periodic. There’s lots here to prompt rich class discussions with pupils of all ages – and some lovely wall art in case you haven’t yet decided about your classroom displays!
If you have a thought-inducing picture, please send a copy (ideally, about 1-2Mb) to us at email@example.com, with a note of where and when it was taken, and any comments on it you may have.
