Children's Mathematics: Making Marks, Making Meaning.
Maulfry Worthington & Elizabeth Carruthers. Published by Paul Chapman Publishing: A SAGE Publications Company.

"After my first book, The Emergence of Literacy, came out in 1987, I waited for someone to write "the emergence of numeracy" and could not understand why nobody did. Now they have. I have only seen it this afternoon, but just skimming through it looks absolutely fascinating. It really ought to appeal to more than maths teachers; in a way it is as much about literacy as mathematics, for numbers are written language"
