These definitions are essential to the study of Mathematics at the target age range. The book provides clear and simple definitions supported by examples and diagrams. Nearly 1000 mathematical terms are defined. The book is a reference for pupils, parents and mathematics teachers who are not mathematics specialists. The publication is an important resource for classroom practitioners for Mathematics. It is intended for teachers to explain clearly most of the Mathematical concepts learners will encounter. This has been done, with the needs of teachers and learners in mind, in a simple way and with examples to illustrate and enhance the meaning and application of key concepts. It is a must have publication. A great resource in the classroom, library and home. The Author has used his extensive experience to highlight the need for such a publication and has undertaken a remarkable task in producing this for practitioners in the classroom.

An experienced Mathematics teacher, founder of after-school classes now in their 19th year, and possessor of an MBE, he is echoing the government's concern about the paucity of black role models for teenagers teetering on the edge of disillusion. "It's not just individual role models either," he said.
