A few days in the past I learn certainly one of Terry Freedman’s newest Substack articles. The article is titled A Dialog I Had Which I Nonetheless Do not Perceive. It is a quick dialogue between Terry and the consultant of a cab firm who cannot clarify why there is a value distinction for 2 journeys of the identical size.
Studying Terry’s story jogged my memory of a Flickr group that Danny Nicholson created greater than a decade in the past. That group known as Unhealthy Maths. The Unhealthy Maths Flickr group comprises a lot of examples of dangerous math noticed in shops and different public locations.
The Unhealthy Maths Flickr group could possibly be a great place to search out some photographs that comprise easy arithmetic issues in your college students to resolve. For instance, ask college students to search out the flaw within the math of this grocery retailer provide or this provide for cat meals.
On the same word to the Unhealthy Maths group, seven years in the past I took the image that you just see beneath. Nearly as quickly because it appeared in my Fb feed through Instagram, my buddy Kelly commented with, “should not they be extra involved about weight than the variety of individuals?” Kelly is a center faculty math instructor so this image was proper in her wheelhouse of math prompts.
