Nicky Hudson, It's all about stories
This is great - it combines hundreds of ideas for "maths" experiences with an approach that is indeed based on play and mess and outdoors and open-ended resources and inspiring possibilities. It's one to read front to back, but also one to pick up and dip into if you are stuck form ideas for experiences based on symmetry, pattern, time, measurement, number or money.The last chapter is my favourite - entitled The Mathematical Garden, it it full of ideas for the outdoor environment from a Froebelian perspective, a childrens' garden which is both inspiring and meaningful.
