It covers the whole mathematical curriculum for primary-age children - the book is divided into sections by age (5-7 years, 7-9 years, 9-11+ years); in each section the development of topics follows a similar pattern and is set out in a framework at the beginning so that the full range of ideas is clearly presented.

The topics covered include: sets, number, pictorial representation, shape (2D and 3D), volume/capacity, area, length, weight, time and money. It's an invaluable aid to any primary school teacher in planning classes and gives a helpful outline of the progression of skills that children can be expected to follow.
