The aim of this book is to offer some help to teachers who are not very confident of their own understanding of mathematics, but want to give some basic help to dyslexics and others in the particular areas needed by them. To that end the chapters give separate topics with clear explanations for the teacher of the content to be taught, suggestions about how to teach it, exercises with answers, and in the Appendix a list of helpful materials and software. Teachers can pick out a topic without necessarily following the order in the book.
