Printed Book
How to Change the World with a Ball of String
The Inca system of record-keeping by tying knots in string (quipu) provided the title of this history book for children. Fact boxes, colourful illustrations, jokes and practical activities make for an anarchic approach to topics ranging from Ancient Sumer and Genghis Khan to Darwin and the moon landings. 8-12 years.
