• Identify, visualise and describe properties of rectangles, triangles, regular polygons and 3-D solids (Y5)
• Recognise parallel and perpendicular lines in grids and shapes; use a set-square and ruler to draw shapes with perpendicular or parallel sides (Y5)
• Calculate angles in a straight line (Y5)
• Describe, identify and visualise parallel and perpendicular edges or faces; use these properties to classify 2-D shapes and 3-D solids (Y6)
• Calculate angles in a triangle or around a point (Y6)
• Classify and visualise properties and patterns
• Use correctly the vocabulary, notation and labelling conventions for lines, angles and shapes
• Identify parallel and perpendicular lines; know the sum of angles at a point, on a straight line and in a triangle; recognise vertically opposite angles
• Identify and use angle, side and symmetry properties of triangles and quadrilaterals; explore geometrical problems involving these properties, explaining reasoning orally, using step-by-step deduction supported by diagrams
• Visualise and manipulate dynamic images
• Identify alternate angles and corresponding angles; understand a proof that:
(i) the sum of the angles of a triangle is 180º and of a quadrilateral is 360º;
(ii) the exterior angle of a triangle is equal to the sum of the two interior opposite angles.
• Solve geometrical problems using side and angle properties of equilateral, isosceles and right-angled triangles and special quadrilaterals, explaining reasoning with diagrams and text; classify quadrilaterals by their geometrical properties
