Shape, space and measures

 

Geometrical reasoning: lines, angles and shapes
	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, and recognise vertically opposite angles.
	Begin to identify and use angle, side and symmetry properties of triangles and quadrilaterals; solve geometrical problems involving these properties, using step-by-step deduction and explaining reasoning with diagrams and text.
	Use 2-D representations to visualise 3-D shapes and deduce some of their properties.

Transformations
	Understand and use the language and notation associated with reflections, translations and rotations.
	Recognise and visualise the transformation and symmetry of a 2-D shape: reflection in given mirror lines, and line symmetry; rotation about a given point, and rotation symmetry; translation; explore these transformations and symmetries using ICT.

Coordinates
	Use conventions and notation for 2-D coordinates in all four quadrants; find coordinates of points determined by geometric information.

Construction and loci
	Use a ruler and protractor to: measure and draw lines to the nearest millimetre and angles, including reflex angles, to the nearest degree; construct a triangle given two sides and the included angle (SAS) or two angles and the included side (ASA); explore these constructions using ICT.
	Use ruler and protractor to construct simple nets of 3-D shapes, e.g. cuboid, regular tetrahedron, square-based pyramid, triangular prism.

Measures and mensuration
	Use names and abbreviations of units of measurement to measure, estimate, calculate and solve problems in everyday contexts involving length, area, mass, capacity, time and angle; convert one metric unit to another (e.g. grams to kilograms); read and interpret scales on a range of measuring instruments.
	Use angle measure; distinguish between and estimate the size of acute, obtuse and reflex angles.
	Know and use the formula for the area of a rectangle; calculate the perimeter and area of shapes made from rectangles.
	Calculate the surface area of cubes and cuboids.
