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.
Wonderful tale by Ben Orlin “Math with Bad Drawings”, of a creature exploring the world of numbers, very much in the spirit of “Flatland”.

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).
"This is a fun and riveting book. Written in an accessible and engaging way, it is unputdownable." Frost Magazine
