Good math bed-time stories for children? What are some good references/books/articles from which to derive some good bed-time math stories to pique a child's interest in math? I am fascinated by math (used to hate it as a kid) and want my kids to be curious about it and fond of playing with the subject.
I was thinking a good way would be to talk about the history/origins of various concepts ideas in math and present them as a "once upon a time" stories and then let them explore the ideas. As a kid I felt a story of "why" behind the what would've been motivating for me to explore the ideas in the field instead of shun them away.
What would be some good math 'stories' to tell them all the way from counting to advanced math (for when they grow older)? I don't mind reading existing books and spin a story on the topics by myself :) Any references to use in particular? Age range 3 to 18 :)

You could always tell the story of the Princess and the Frog.
