1. This website was inspired by the MTBoS
        with special thanks to Christopher Danielson and his Which One Doesn't Belong - A Shapes Book.
        This is Which One Doesn't Belong?, a website dedicated to providing thought-provoking puzzles for math teachers and students alike. There are no answers provided as there are many different, correct ways of choosing which one doesn't belong. Enjoy!
