A Million Dots is the winner of the New York Times Illustrated Children's Book Award 2019! It's a stunning graphic visualisation of numbers, starting with 1 (a single tree) and doubling the number on next page, all the way up to 1 million (actually 1,048,576) in 44 pages.
Each number is brought to life with a simple graphic illustration, like dots on the back of a ladybird, bubbles in a drink, water in a swimming pool. On each page, a single neon dot illustrates what one means in the context of the sum. This is a brilliantly way of conceptualising numbers and maths to kids.
