This book offers a background review of the problems dyslexics face in mathematics, a philosophy of teaching approaches, a diagnostic procedure and practical suggestions on how to teach a range of mathematical topics. Although written by teachers working with pupils aged 10 and above, the level of topic they cover may also be applied to a much younger age group. For the second edition the chapters on basic numeracy have been revised to show the further evolution of teaching philosophies into a unified and developmental programme which sets firm foundations for more advanced mathematics. The chapters on percentages and time have been expanded and there are new chapters on positive and negative numbers and teaching the National Curriculum. A summary of the ever changing field of computer technology is also included. Elsewhere the chapters have been updated and adjusted to take account of new research and ideas as well as feedback on the first edition.
