Mathematics, Instruction Methods 

One of the aims of the book is to recognize the material conditions under which teachers in many overseas countries work. The intention has been to encourage teachers to use locally available materials where possible. The best compromise is, to talk in terms of what was available in one place at a certain time as examples. The basic theme of the book is that mathematics is a subject which is learnt by understanding rather than by blind memorization. This book began life as a series of duplicated typewritten sheets, used by the authors to aid their work in a primary mathematics project in Sierra Leone. The audience was mainly one of primary school teachers and students in training. The original manuscript made many specific references to Sierra Leonean customs and colloquialisms. These have been removed to make the book accessible to a wider audience. - from Amzon
