Math puzzles to get students talking about their mathematical thinking. The site provides a collection of shape, number and graph sets. Each activity has four images/numbers, students then need to pick which one doesn't belong. But the trick is this, the puzzles do not have one correct answer. This can lead to interesting conversation and descriptions of what the student notices about the arrangement.
If you think up your own, you can submit them to the site.
