More Fun With Math in Pictures

I love Instagram because it prompts me to take and share pictures of things that I might otherwise glance at then forget about. Before cell phones entered my life I rarely took pictures. Last week I took the picture that you see below. Almost as soon as it appeared in my Facebook feed via Instagram, my friend Kelly commented with, "shouldn't they be more concerned about weight than the number of people?" Kelly is a middle school math teacher so this picture was right in her wheelhouse of math prompts. (If you want to use the picture as a math prompt, you are welcome to download it).

Kelly's comment reminded me of the Bad Maths Flickr group which contains lots of examples of bad math spotted in stores and other public places. Some of the bad math is obvious as in this picture taken in a Walmart store. Other examples are not as obvious.

Along the same lines of taking math pictures, last year Andy McKiel shared a neat mathematics and photography project started by a grade 3 class in Thompson, Manitoba. The project asked students to take photographs of things representing various topics and concepts in elementary school level mathematics. There was a different concept for each day of the month of May. You can certainly modify the project to suit another month of the year.
