MG 42 – AREA OF SHAPES USING SQUARE CENTIMETRE AND SQUARE METRE GRIDS
Children investigate the distinction between square centimetres vs centimetres square/d, square metres vs metres square/d.
Children measure the area of shapes in square centimetres and square metres using a grid in square centimetres and square metres.
Children explain the units used to measure area in the metric system are the units used to measure length turned into squares by extending into second dimension – integrated metric length Measurement and Geometry 30, Measurement and Geometry 39.
The metric measurement system is based on multiplicative place value – integrated Place Value 18, Place Value 20 Fractions and Decimals 11, Place Value 21 Fractions and Decimals 12.
