Measurement > Perimeter and Area

Australian Curriculum Version 9 Says:

Solve practical problems involving the perimeter and area of regular and irregular shapes using appropriate metric units.

What this means

Calculating perimeter and working out the approximate area of shapes.

  • Formulas are not mentioned.
  • Perimeter is found by adding lengths.
  • Area is found by direct measurement, that is placing squares on top of shapes to determine the area.

Tips

  • No further reference to perimeter is made in Year 6.
  • When counting squares to determine area count any half squares or larger. Do not worry about the rest.
