Hello Math Teachers,
Which One Doesn't Belong is a collection of shapes, numbers, and other math representations that I present as morning work or warm-up before math. Curation is done on the web by Mary Bourassa and is inspired by the Christopher Danielson book of shapes, but I mostly have Sesame Street stuck in my head as I share one of these with students. Nothing too complex, but it does present a good challenge at first for those students who are sure that there must be a correct answer. Students then have great discussion (argument!) how each shape has a quality that is different than the others. In the subsequent examples, the students know that their claims are important, but must be backed up with evidence and reasons why (good practice for math and science practice standards to argue from evidence). The collection includes examples with money, numbers, clocks, games, and some seasonal pictures that are just fun: Check out the full collection here: http://wodb.ca/index.html I use Google Slides to share them with my class, you can access the slideshow here They even inspire student created examples. Here is one from Mariska in Team 508: Comments are closed.
