What’s it about?

The story.

This is a counting book quite unlike any other. Instead of stopping at ten, it begins at zero, an octopus has zero bones, and journeys all the way up through the single digits and the powers of ten to nine billion, pinning an astonishing fact about the natural world to every number along the way. From the creatures of the ocean to the reaches of space to the workings of the human body, each spread uses a number as a doorway into wonder, inviting curious children to see the world through the lens of quantity and scale. Anne Richardson, drawing on years at the Exploratorium science museum, pairs her fact-filled text with Andrea Antinori's award-winning, playful illustrations. A browsable, endlessly re-readable book that makes maths and science feel like the same thrilling act of noticing.
