Check a result by considering whether it is of the right order of magnitude and by working the problem backwards.
Carry out calculations with more than one step using brackets and the memory; use the square root and sign change keys.
Interpret the display of a calculator in different contexts (decimals, percentages).
Calculate simple fractions of quantities and measurements (whole-number answers); multiply a fraction by an integer.
Recognise the equivalence of percentages, fractions and decimals; calculate simple percentages and use percentages to compare simple proportions.
Break a complex calculation into simpler steps, choosing and using appropriate and efficient operations, methods and resources, including ICT.

Calculate fractions of quantities and measurements (fraction answers); multiply and divide an integer by a fraction.
Recognise reflection symmetry.
Recognise where a shape will be after reflection.
Recognise where a shape will be after a translation.
Calculate angles on a straight line, in a triangle, or around a point.
Use a protractor to measure and draw acute and obtuse angles to the nearest degree. Visualise 3-D shapes from 2-D drawings and identify different nets for a closed cube.
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.
Explore transformations and symmetries using ICT.
Use a ruler and protractor to: -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 a ruler and protractor to construct simple nets of 3-D shapes, e.g. cuboid, regular tetrahedron, square-based pyramid, triangular prism.
Solve geometrical problems using side and angle properties of equilateral, isosceles and right-angled triangles and special quadrilaterals.
Classify quadrilaterals by their geometric properties.
Use straight edge and compasses to construct:
-the mid-point and perpendicular bisector of a line segment;
-the bisector of an angle;
construct a triangle given three sides (SSS).
