What new light do such machines throw on age-old discussions of the teaching and learning of mathematics, in particular, the common tension between fluency and understanding? What new perspective is cast on the question not ‘what is there is be known?’ but rather ‘what is worth knowing?’ in mathematics? David Pimm is senior lecturer in mathematics education at The Open University. What does the omnipresence of this term describing the doing of mathematics tell us about the two fundamental metaphors in English for understanding: touch and sight? The book also addresses a set of questions of particular relevance to the last decade of the twentieth century, which arise due to the rapidlyincreasing proliferation of machines offering mathematical functionings.

Practical apparatus in North America is known as ‘manipulatives’, some recent computer software is known as a ‘symbolic manipulator’ and we are taught to manipulate numbers, algebraic expressions, and geometric figures and images. One theme which runs throughout the book is the core metaphor of manipulation. It is in the interplay between language, image and object that mathematics is created and can be communicated to others. It is concerned with the power of language which enables us to do mathematics, giving us the ability to name and rename, to transform names and to use names and descriptions to conjure, communicate and control our images. Symbols and Meanings in School Mathematics explores the various uses and aspects of symbols in school mathematics and also examines the notion of mathe matical meaning.
