Is That a Big Number is now a book, published by Oxford University Press. (Google ISBN 0198821220 to find many online booksellers). Although there is serious purpose behind the book - to explore how we think about numbers and how we can understand big numbers - it’s written in a light and engaging style.
Entertaining, full of practical examples, and memorable concepts, Is That A Big Number? renews our relationship with numeracy. If numbers are the musical notes with which the symphony of the universe is written, and you’re struggling to hear the tune, then this is the book to get you humming again.
This article about log scales and how to think about them (and how they naturally reflect how we think about big numbers) pretty much nails it, for me. Using log scales is an essential tool in your mental numeracy toolbox.
Thank you, Chalkface blog.
Thank you, too, Vi Hart for your passionate and engaging video on the topic.
This thought-provoking blog post accurately describes one of the most important reasons for mathematical (and other) education: for the habits of thought and not always only for the content.
Numeracy, and a numerate approach to understanding the world, becomes a habit also. Keep asking: “is that a big number?”

Take a bunch of everyday stuff (not just clothes) and weigh them. Why? Just to see how much they weigh! (and along the way maybe help internalise a sense of relative weights).
Yes, there's now an engaging, informative book based on these numbers. Oxford University Press: July 2018.
