Revise: Basic Number Skills, Scale, and PercentagesGeographical numbers describe different things: a population is a count of people, a river's width is a length, and a woodland's area measures the surface it covers. A number needs its context and, where appropriate, its unit to make its meaning clear. A distance of 500 metres is very different from 500 kilometres.
