Area is a twodimensional concept related to the geometric concept of an enclosed region. It is defined in the maths curriculum as the size of a surface expressed as a number of square units. Investigations of the size of an area should begin with comparisons between different surfaces and progress to the use of nonstandard, and then standard, units. The use of formulae to calculate the areas of common polygons is the final stage of the learning sequence.
