This is a book that really shows children the process of wondering at the world; the way that taking time to notice things, and not always conforming to the expectations of those around us, can lead to amazing discoveries and world changing inspirations. The illustrations are very stylised and some might find them dated, but as a story it's well told, and there is so much Maths to talk about! From multiplication to patterns, to the history of Roman numerals versus arabic ones, and the uses of Maths in every day life, there are so many jumping off points for discussion. For children who love to wonder, it's an inspiring and affirming read.
