Robert Kaplinsky’s Real World Problems

Robert Kaplinsky uses images from everyday life to pose interesting math challenges for students in Kinder through high school.  You can choose problems by grade level on his site, or you can look at this spreadsheet that identifies the Common Core Standards covered in each problem.

Questions like, “How Many Combos are there on a Coke Freestyle?” are sure to elicit curiosity from your students.  Kaplinsky shares the image, a challenge, questions to be asked by the teacher to encourage discussion, and background information regarding the facts and the math related to each image.

Robert’s site inspired me to look for some other free images that might spawn some intriguing math questions, and I found this one on Pixabay:


Can you think of math questions for your own students that would correlate to this picture?

By the way, I’ll be adding this to my, “15 Math Sites that Won’t Make You Fall Asleep” post – which will actually make the current number of recommended sites 17 at this point 😉

  1. I love using photos in math and will have to spend some time checking out the resources on this site. I will put up a pic and then ask my students to come up with unanswered math questions-so they ask how many, about shapes, temperature, etc. It really helps them start to be able to differentiate reading from math. 🙂
