My Garden is a Square: A Journey Through the Home of Numbers and Shapes. This rhyming children’s picture book enables young readers to see the patterns and structures in numbers and shapes through the magical world of Numberland; a land where numbers come to life and have their own houses and gardens! The story and pictures inspire us to find mathematics in the world around us: Number Four has 4 braids in her hair and 4 flowers in her square garden… Why? And what else can you find? The concept of Numberland was first conceived in 2004 from research into children’s mathematical development by Dr Gerhard Friedrich of Germany.
