What does this train?
Categorization is one of the first abstract thinking skills children develop. Spotting the odd one trains the child to find the rule that unites the group, not just to pattern-match. We picked categories that go beyond shape — animals vs vehicles, fruit vs vegetable, things-that-fly vs things-that-don't.
