Students make, describe and compare
measurements of length, area, volume, mass and time using informal units.

Calculation of
area through multiplication of the length of a rectangle by its width

Students
estimate and measure length, area, volume, capacity, mass and time using
appropriate instruments

Estimation and measurement of perimeter of
polygons

Estimation and measurement of surface area;
for example, use of square metres, and area of land; for example, use of
hectares

Students use
metric units to estimate and measure length, perimeter, area, surface area,
mass, volume, capacity time and temperature

Development and
use of formulas for the area and perimeter of triangles and parallelograms.

Students measure length, perimeter, area, surface area, mass,
volume, capacity, angle, time and temperature using suitable units for these
measurements in context.
They interpret and use measurement formulas for the area and
perimeter of circles, triangles and parallelograms and simple composite
shapes.
.

They interpret
and use mensuration formulas for calculating the perimeter, surface area and
volume of familiar two and threedimensional shapes and simple composites of
these shapes.
