Scales can be used to show large amounts. When the numbers get too cramped the scales are often simplified and a label is used to show the value of the numbers used on the scale. Scales are a bit like number lines. On a measuring jug the scale goes upwards rather than across. It is read up from the bottom. On weighing scales there may be a circular scale. An arrow rotates clockwise and the numbers may be displayed around the edge. While this scale goes in a circle it is really just another type of number line.
