A description of the domain of measurement

Measurement is a way to gain control of reality. For example, we talk about how big something is or how heavy it is. Or we wonder how far away something is, how much it costs, how sweet it is, how hot it is, or how long something lasts. Measurement is a specific mathematical approach to reality. If we want pupils to learn to look at reality in a similar fashion, we must encourage them to structure and quantify situations in reality. For many children, this appears to be difficult.
