First Published in 2001. Starting with references to the Cockcroft Report of 1982 and the National Strategy, this study defines numeracy as mathematics in action and outlines its importance in everyday life. Using and applying mathematics within the early learning setting means children are also taught to solve problems, to communicate their ideas and develop their reasoning skills. Teaching Assistants provide the most effective support in mathematics when working in partnership with the teacher, by sharing goals. To do this effectively it is important for assistants to understand how mathematics learning takes place within the early years setting and to know how and when to use mathematics language and equipment. The purpose of this book is to provide such understanding and knowledge.
