Progression Point

Measurement, chance and data

2.0 Standard

… Students recognise the differences between non-uniform measures, such as hand-spans, to measure length, and uniform measures, such as icy-pole sticks.

2.25

• 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

3.0 Standard

… Students recognise and use different units of measurement including informal (for example, paces), formal (for example, centimetres) and standard metric measures (for example, metre) in appropriate contexts.

3.25

• Conversion between metric measurements for length; for example, 0.27m = 27cm

3.75

• Conversion between metric units; for example, L to mL, and understanding of the significance of thousands and thousandths in the metric system

4.0 Standard

… Students convert between metric units of length, capacity and time (for example, L–mL, sec–min).

5.25

• Conversion between units and between derived units

5.75

• Conversion between degrees and radians, and use of radians when calculating arc length and area of sectors

6.0 Standard

… Students select and use appropriate units, converting between units as required.
