Students are provided opportunities to:
- select and apply appropriate strategies to solve multiplication and division problems
- estimate and measure areas of rectangles and composite shapes using square centimetres and square metres
- recognise the relationship between the dimensions of a prism and its volume to calculate volumes in cubic centimetres and cubic metres.
Multiplicative relations A – MAO-WM-01, MA3-MR-01
- Determine products and factors
- Use partitioning and place value to multiply 2-, 3- and 4-digit numbers by one-digit numbers
- Use estimation and rounding to check the reasonableness of answers to calculations
