3 1 A student: describes and represents mathematical situations in a variety of ways using mathematical terminology and some conventions MA31WM gives a valid reason for supporting one possible solution over another MA33WM selects and uses the appropriate unit to estimate, measure and calculate volumes and capacities, and converts between units of capacity MA311MG Students: Choose appropriate units of measurement for volume and capacity (ACMMG108) select and use appropriate units to measure the capacities of a variety of containers, eg millilitres for a drinking glass, litres for a water urn measure the volumes of rectangular containers by packing them with cubic-centimetre blocks explain the advantages and disadvantages of using cubic-centimetre blocks as a unit to measure volume (Communicating, Reasoning) describe arrangements of cubic-centimetre blocks in containers in terms of layers, eg 5 layers of 8 cubic-centimetre blocks (Problem Solving) recognise the need for a formal unit larger than the cubic centimetre construct and use the cubic metre as a unit to measure larger volumes explain why volume is measured in cubic metres in certain situations, eg wood bark, soil, concrete (Communicating, Reasoning) recognise that a cubic metre can have dimensions other than a cube of side 1 metre, eg 2 metres by metre by 1 metre (Problem Solving) record volumes using the abbreviation for cubic metres (m3) estimate the size of a cubic metre, half a cubic metre and two cubic metres select and use appropriate units to estimate the volumes of a variety of objects, eg cubic centimetres for a lolly jar, cubic metres for the classroom Background Information The attribute of volume is the amount of space occupied by an object or substance and is usually measured in cubic units, eg cubic centimetres (cm3) and cubic metres (m3). Capacity refers to the amount a container can hold and is measured in units, such as millilitres (mL), litres (L) and kilolitres (kL). Capacity is only used in relation to containers and generally
