    In your question with the 4 x 5 blue rectangle, it’s like those “genius” quizzes, where they expect everyone to say “20,” but the actual answer is 40 or whatever, if you count ALL of the possible squares. That is to say, a 2 x 2 square is also a square. That might be a good way to demonstrate it for kids–that even “square” is not a specific enough unit for the answer. I also love Ruth Hicks’s idea of putting answers in unusual units, just for the practice of it–4 is also 12 thirds is also 40 tenths, is also . . .
