Use hectares and square kilometres as units of measurement for area

• Recognise the need for formal units larger than the square metre

• Identify situations where square kilometres and hectares are used for measuring area

• Equate one hectare to the area of a square with side lengths of 100 m, ie 10 000 square metres = 1 hectare (ha)

• Record areas using square kilometres and hectares

Calculate the areas of rectangles using familiar metric units

• Recognise the importance of using the same units of length on the sides of rectangles to create ‘square units’

• Establish the relationship between the lengths, widths and areas of rectangles

• Record, using words, the method for finding the area of any rectangle

• Calculate areas of rectangles in square centimetres (cm2), square metres (m2) and square kilometres (km2)

• Recognise that rectangles with the same area may have different dimensions

• Investigate and compare the areas of rectangles that have the same perimeter
