Geometry and Measurement: Measurement, Level 2
AO1: Create and use appropriate units and devices to measure length, area, volume and capacity, weight (mass), turn (angle), temperature, and time. This means students will recognise that the attributes length, area, volume and capacity, and weight can be measured. At Level Two students are expected to recognise that measurement units are countable and therefore able to be partitioned and recombined in the same way as other units of one, e.g. If a 8 unit length is cut from a 14 unit long strip the remainder will measure 6 units. Units of measure have other characteristics including being a part of the attribute they measure and uniformity (same size). When measuring the units need to fill a length, space, time etc, with no gaps or overlaps (this is known as tiling). Students should create measurement devices, e.g. rulers, rod towers, scales, to quantify the attributes of objects in numbers of units. In doing so they should develop an understanding that the marks on a linear scale show the endpoint of units and that scales always have a baseline (zero). Less tangible attributes such as turn (angle), temperature and time should also be measured. While the focus at Level Two is on students’ understanding the role of units in measurement it is also expected that students will encounter simple standard measures such as metres, centimetres, kilometres, minutes, seconds, kilograms, litres, etc, through using everyday measurement instruments.
AO2: Partition and/or combine like measures and communicate them, using numbers and units. This means students will perform and communicate calculations involving like measures. Like measures involve the same units for the same attribute. This allows the result of joining or separating units to be anticipated using additive number strategies, e.g. A box has a volume of 36 cubes. If a 3 by 4 cube layer is put in the empty box then there will be space for 36 – 12 = 24 more cubes. At Level Two students should be able to use numbers and common symbols to communicate measurement results, e.g. my lunchbox holds 60 cubes. I took 13 minutes to walk home. My pencil is 14 cm long. I weigh 26 kg.
