I bought this as I am an adult literacy and numeracy tutor and wanted a book I could recommend for extra home study to my students - this is definitely the one. Starting from scratch, the book gives clear, practical examples of numeracy problems and takes the student through them step by step. The book contains lots of interesting facts that makes numeracy come alive for the student- if you've ever wondered why zero Fahrenheit is so far below zero Celsius, this book gives a possible explanation.
Plenty of examples are given in the areas learners seem to find most challenging- for example, how to calculate ratios and metric conversions. The book is broken down into easy to find, meaningful sections that broadly map to the Adult Numeracy curriculum, starting with whole numbers and ending with data. Illustrations are plentiful, clear and helpful. There are several useful appendices, containing tables and the old/new favourite, a learning styles questionnaire.
If you are wanting to study at home to pass the National Tests in Numeracy and prefer paper-based materials to studying on the Internet,- or perhaps there are no dedicated numeracy classes in your area - this book is very much written for you.
