Stage 1 -measurement – volume
Students need experience in filling containers both with continuous material (e.g. water) and with discrete objects (for example, marbles). The use of continuous material leads to measurement using the unit’s litre and millilitre in later stages. The use of blocks leads to measurement using the units’ cubic metre and cubic centimetre.
- count the number of informal units in a prism
- visualise the hidden units in a pictorial display
Activities to support the strategy
Using concrete materials (blocks), students build three-dimensional structures
- How many blocks were used to produce these objects?
- How many blocks are missing from diagram B?
Ask students to state the number of cubes that cannot be seen in each stack.
