Stage 3

Two-dimensional spatial structure A
2D shapes: Classify two-dimensional shapes and describe their properties

  • Identify and classify Loading  as equilateral, isosceles or scalene triangles

  • Recognise that triangles and quadrilaterals can be classified in more than one way (Reasons about spatial relations)

  • Compare side and Loading  properties of triangles and quadrilaterals using measurement and symmetry

  • Investigate the symmetry properties (Loading  and rotational) of quadrilaterals

  • Identify regular and irregular Loading 

Area: 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 Loading  with side Loading  of 100 m,

    ie 10 000 square metres = 1 hectare (ha)

  • Record areas using square kilometres and hectares

Area: 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
