Although as recently as 1968 the World Federation of Neurology defined dyslexia only in terms of language skill difficulties, it now seems established that many dyslexics have difficulty in at least some aspects of mathematics. 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.
