● use of formal units of measurement; for example, metres to measure length, and hour, minute and second for time

● application of estimations using personal units, such as pace length and arm span, and comparison with measures using formal units, such as metres and centimetres

● use of ruler and tape measure (linear scale) and trundle wheel (circular scale) to validate estimates of length

● setting of temperature in Celsius on a circular scale; for example, on an oven, and estimation of temperature in degrees Celsius
