MA1-3DS-01 recognises, describes and represents familiar three-dimensional objectsMA1-3DS-02 measures, records, compares and estimates internal volumes (capacities) and volumes using uniform informal unitsContent dot points
Each dot point has its own page with resources matched to it.
3D objects: Recognise familiar three-dimensional objects
- Use the term ‘three-dimensional’ to describe a range of objects
- Distinguish between objects, which are three-dimensional (3D) and shapes which are two-dimensional (2D)
- Identify and name familiar three-dimensional objects, including cubes, cylinders, spheres and rectangular prisms
3D objects: Sort and describe three-dimensional objects
- Manipulate and describe familiar three-dimensional objects
- Use the term ‘ surface ' in describing familiar three-dimensional objects
- Sort familiar three-dimensional objects according to obvious features
- Use the term ‘ face ’ to describe the flat surfaces of three-dimensional objects with straight edges
- Select and name a familiar three-dimensional object from a description of its features
Volume: Measure and compare the internal volumes (capacities) of containers by filling
- Use uniform informal units to measure how much a container will hold by counting the number of times a smaller container can be filled and emptied into the container being measured
- Select appropriate informal units to measure the capacities of containers
- Recognise and explain the relationship between the size of a unit and the number of units needed (Reasons about relations)
- Compare the internal volumes of two or more containers using appropriate uniform informal units
- Recognise and explain why containers of different shapes may have the same internal volume (Reasons about relations)
- Estimate how much a container holds by referring to the number and type of uniform informal unit used and check by measuring
Volume: Measure the internal volume (capacity) of containers by packing
- Pack cubic units (eg blocks) into rectangular containers so that there are no gaps
- Recognise that cubes pack better than other objects in rectangular containers (Reasons about spatial structure)
- Estimate and measure the internal volume of a container by filling the container with uniform informal units and counting the number of units used
- Explain that if there are gaps when packing and stacking, this will affect the accuracy of measuring the internal volume
Volume: Construct volumes using cubes
- Explore different rectangular prisms that can be made from a given number of cubes
- Devise and explain strategies for stacking and counting units to form a rectangular prism (Reasons about spatial structure)
- Record volumes, referring to the number and type of uniform informal unit used
