Geometry

SUBJECT: Maths – Geometry – properties of shapes

Year

Key Concepts (Statutory Requirements)

Year 1

 

 

 

 

 

  • recognise and name common 2-D and 3-D shapes, including:
  • 2-D shapes [for example, rectangles (including squares), circles and triangles]
  • 3-D shapes [for example, cuboids (including cubes), pyramids and spheres].

 

Year 2

 

 

 

  • identify and describe the properties of 2-D shapes, including the number of sides and line symmetry in a vertical line
  • identify and describe the properties of 3-D shapes, including the number of edges, vertices and faces
  • identify 2-D shapes on the surface of 3-D shapes, [for example, a circle on a cylinder and a triangle on a pyramid]
  • compare and sort common 2-D and 3-D shapes and everyday objects.

 

Year 3

 

 

  • draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
  • recognise angles as a property of shape or a description of a turn
  • identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle
  • identify horizontal and vertical lines and pairs of perpendicular and parallel lines.

 

Year 4

 

 

  • compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes
  • identify acute and obtuse angles and compare and order angles up to two right angles by size
  • identify lines of symmetry in 2-D shapes presented in different orientations
  • complete a simple symmetric figure with respect to a specific line of symmetry.

 

Year 5

 

 

  • identify 3-D shapes, including cubes and other cuboids, from 2-D representations
  • know angles are measured in degrees: estimate and compare acute, obtuse and reflex angles
  • draw given angles, and measure them in degrees (o)
  • identify:
  • angles at a point and one whole turn (total 360o)
  • angles at a point on a straight line and a half turn (total 180o)
  • other multiples of 90o
  • use the properties of rectangles to deduce related facts and find missing lengths and angles
  • distinguish between regular and irregular polygons based on reasoning about equal sides and angles.

Year 6

 

 

  • draw 2-D shapes using given dimensions and angles
  • recognise, describe and build simple 3-D shapes, including making nets
  • compare and classify geometric shapes based on their properties and sizes and find unknown angles in any triangles, quadrilaterals, and regular polygons
  • illustrate and name parts of circles, including radius, diameter and circumference and know that the diameter is twice the radius
  • recognise angles where they meet at a point, are on a straight line, or are vertically opposite, and find missing angles.
