Inspired by a trip to Tescos recently where I saw this special offer, and by the Atrocious Apostrophe’s flickr group for all those instances of terrible punctuation, I decided to set up the Bad Maths Flickr group.

Bad maths

The aim is to collate any examples of bad maths out there in the real world. These images can then be used in maths lessons with students, getting them to spot the errors. It’s a fledgling group, but hopefully will grow.

If you’d like to submit any examples I’d love to have them in the group. Join here, and submit your flickr photos!
