This timely book provides a detailed and comprehensive overview of the teaching and learning of numeracy in primary schools. It will be particularly helpful to teachers, mathematics co-ordinators and numeracy consultants involved in the implementation of the National Numeracy Strategy. It presents an accessible guide to current British and Dutch research into numeracy teaching. Leading researchers describe their findings and discuss implications for practising teachers. The projects include studies of effective teachers of numeracy, ICT and numeracy, an evaluation of international primary textbooks, assessment, using and applying mathematics and family numeracy. The book also includes chapters on pedagogy, focusing on the teaching of mental calculation, the transition from mental to written algorithms, the place of the empty number line and the use of the calculator as a teaching aid. Most chapters include practical suggestions for helping teachers develop aspects of their numeracy teaching skills.
