The measurement framework

The focus of the measurement aspect of the continuum is the identification of units and the development of the structure of units used in measuring length, area and volume. Measurement may also involve comparison, such as determining the longest string, or the container that holds the most.

The measurement framework brings together length, area and volume by reinforcing the similarity of the processes involved in measurement of quantities where the units are spatially organised. Measurement enables continuous quantities, those which are not separately countable, to be compared and ordered. A fundamental difference between measuring and counting a discrete quantity is that in measurement the units are not visible unless concrete units are used or the units are constructed or drawn. The items in discrete quantities such as a box of apples or a group of children can be individually counted. To measure a continuous quantity requires partitioning it into units that can be counted.
