Stage 3, mathematics, Year B – Unit 29

This 2-week, Year B unit develops the big idea that what needs to be measured determines the unit of measurement.

Students are provided opportunities to:

• compare the properties of prisms and pyramids by visualising, naming and sketching nets of three-dimensional objects
• compare volumes of 2 or more objects by observing the change in water level when objects are submerged in a container of water
• recognise the equivalence of whole-number and decimal representations by measuring, comparing and ordering measurements of capacities of up to 3 decimal places.
