Winner of the New York Times Top 10 Best Illustrated Children's Books of 2019.A book to promote interest in numbers and wonder at the scale they can represent, with lots to interrogate and talk about. -- School Library AssociationPotential goldmine of teaching ideas. -- School Reading ListDouble the numbers to go from 1 to 1,000,000 in 40 pages. A stunning visualization of numbers big and small.We start with a single tree; 1. As we turn the page, we are presented with a sum doubling the number on the page before it: 1+1 = 2; 2+2 = 4; 4+4 = 8. In this way, we reach a million (actually 1,048,576) within 44 pages.Each sum is brought to life with a simple graphic illustration in the distinctive style of Sven Völker. The dots form the back of a ladybird, the bubbles in a cup of soda and the water in a swimming pool. On each page, a single neon dot illustrates what one means in the context of the sum.Gloriously simple in its concept and execution, this is a book that will bring mathematics alive to parents as well as children and will also make a stunning gift book.
