Cockburn (education, U. of East Anglia, Norwich) and Littler (mathematics education, Charles U., Prague) have edited this mathematics guide for teachers who need to understand how young children acquire concepts about numbers. Contributors from the fields of mathematics, psychology and education converge to explain how children comprehend and use numbers at an early age, and why their preconceptions can influence the learning process. These articles explore such topics as understanding the properties of zero, defining mathematical equalities and common misconceptions about basic math operations such as adding and subtracting.
