This publication is a resource for those who teach basic mathematics to adults. It assumes very little knowledge or formal mathematics by teachers, tutors and students and provides background, strategies and rationale for people inexperienced in teaching adult numeracy as well as new ideas for the experienced teacher. The worksheets and activities have been especially designed for adults and the language used is suitable for students with low level literacy skills. The book is divided into six sections: Getting Started; Exploring Numbers; Addition and Subtraction; Multiplication and Division; Money and Metrics; and Fractions and Percentages. The materials and methods used in this book encourage students to learn through interaction and co-operation, which involves the use of discussion, practical activities and hands on materials.
