This book lives up to its subtitle completely; it is indeed a practical guide to helping learners with numeracy difficulties. There is a fascinating introduction to dyscalculia and numeracy difficulties - Steve Chinn is a master at the art of interesting academic writing. He informs at the highest level without ever losing your interest.
Vital facts are summarised in bullet point format that make skim reading easy. Crucially, problems are not just described, but solutions are offered. Not just one or two solutions for general problems, but pages of them.
General reference throughout is made to the schools curriculum rather than the adult numeracy curriculum but this does not mean that the book is not of value to those in adult learning. Many of the suggested resources can be quickly and easily prepared, building up a valuable bank of aids to support lessons.
There is a lengthy and detailed section on thinking styles in mathematics (inchworm/grasshopper) which really informs those wishing to know about the topic - a great reference for trainee teachers/tutors.
Not the cheapest resource but an invaluable one for aspiring and existing assistants, tutors and teachers. An goldmine of ideas for making numeracy sessions inclusive for all.
