By Juliet Robertson (Independent Thinking Press, £18.99)
In this reference book, the author reimagines the outdoor space through a mathematical lens. Ready-to-use games and open-ended ideas concentrate on finding number, shape and space through the endless supply of patterns, textures, colours and quantities you find in the natural world. As well as boosting practitioners’ confidence when it comes to maths, the book aims to enable children to have lots of informal, spontaneous mathematical experiences. From age three.
