MA3-3DS-01 visualises, sketches and constructs three-dimensional objects, including prisms and pyramids, making connections to two-dimensional representations MA3-3DS-02 selects and uses the appropriate unit to estimate, measure and calculate volumes and capacities
Prior Knowledge
- Three-dimensional Spatial Structure (Stage 2)
3D objects: Compare, describe and name prisms and pyramids
- Compare properties of prisms and pyramids
- Name prisms and pyramids according to the shape of their base
3D objects: Connect three-dimensional objects with two-dimensional representations
- Visualise and sketch three-dimensional objects from different views, including top, front and side views (Reasons about spatial orientation)
- Examine a diagram to determine whether it is or is not the net of a closed 3-dimensional object
- Visualise and sketch nets for given three-dimensional objects
- Visualise and name prisms and pyramids, given representations of their nets (Reasons about spatial visualisation)
Volume: Choose appropriate units of measurement for capacity
- Select and use appropriate units to measure the capacities of a variety of containers
Volume: Use displacement to investigate volumes of irregular solids
- Recognise that an object’s volume takes up space by observing the change in water level when an object is placed in a container of water
- Compare the volumes of 2 or more objects by marking the change in water level when each is submerged in a container
Volume: Connect decimal representations to the metric system
- Recognise the equivalence of whole-number and decimal representations of measurements of capacities
- Interpret decimal notation for capacities
- Record measurements to 3 decimal places
