Shape and space in the primary curriculum
 

2-D shapes - fifth and sixth class

Content for fifth class

The child should be enabled to

  • Make informal deductions about 2-D shapes and their properties
  • Use angle and line properties to classify and describe triangles and quadrilaterals.
    Name, explore and compare a wide variety of three and four-sided figures in terms of size and number of angles, type and number of sides e.g. trapezium, scalene triangle and regular hexagon?
  • Identify the properties of the circle?
    Explore and compare circles of various unit diameters?
    Measure and identify the relationship of diameter to radius?
    Examine area by counting square units?
  • Construct a circle of given radius or diameter?
    Draw using a compass.
  • Tessellate combinations of 2-D shapes
  • Classify 2-D shapes according to their lines of symmetry.
    Explore, compare and record lines of symmetry in 2-D shapes?
  • Use 2-D shapes and properties to solve problems.
    Make a specified shape with Tangram shapes.

Content for sixth class

The child should be enabled to

  • Make informal deductions about 2-D shapes and their properties
  • Use angle and line properties to classify and describe triangles and quadrilaterals
  • Construct triangles from given sides or angles.
    Complete the construction of triangles, given two sides and the angle between them or given two angles and the line between them.
  • Identify the properties of the circle?
    Relate the diameter of a circle to its circumference by measurement.
    Measure the circumference of a circle or object such as a rolling-pin or wheel e.g. using a piece of string.
  • Construct a circle of given radius or diameter?
  • Tessellate combinations of 2-D shapes
  • Construct a circle of given radius or diameter?
  • Classify 2-D shapes according to their lines of symmetry
  • Plot simple co-ordinates and apply where appropriate.
    Use geoboards and squared paper.
  • Use 2-D shapes and properties to solve problems.
