To achieve this, students require an understanding of the nature of the different physical attributes that can be measured and the way units are used to quantify amounts of such attributes to needed levels of accuracy. It also requires the ability and understandings needed to make informed judgments about measurements for a range of purposes and to calculate measurement indirectly using measurement relationships. Learning experiences should be provided that will enable students to understand units, directly and indirectly measure, and estimate measurements.
As a result of their learning experiences, students at all levels should be able to achieve the following outcomes.
Understand Units
Decide what needs to be measured by selecting what attributes to measure and what units to use.
Direct Measure
Carry out measurements of length, capacity/volume, mass, area, time and angle to needed levels of accuracy.
Indirect Measure
Select, interpret and combine measurements, measurement relationships and formulae to determine other measures indirectly.
Estimate
Make sensible direct and indirect estimates of quantities and be alert to the reasonableness of measurements and results.
