All should be able to
Develop calculator skills and use a calculator effectively.
Use, read and write standard metric units of length, mass and capacity.
Suggest suitable units and measuring equipment to estimate or measure length, mass or capacity.
Use all four operations to solve word problems, including time.
Most should be able to
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.
Use names and abbreviations of units of measurement to measure, estimate, calculate and solve problems in everyday contexts involving length, area, mass, capacity and time;
convert one metric unit to another (e.g. grams to kilograms); read and interpret scales on a range of measuring instruments.
Break a complex calculation into simpler steps, choosing and using appropriate and efficient operations, methods and resources, including ICT.
Present and interpret solutions in the context of the original problem; explain and justify methods and conclusions, orally and in writing.
Some should be able to
Know rough metric equivalents of imperial measures in daily use.
Give solutions to an appropriate degree of accuracy in the context of the problem.
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.
Calculate angles in a triangle or around a point.
Use a protractor to measure and draw acute and obtuse angles to the nearest degree.
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.
Use a ruler and protractor to:
-measure and draw lines to 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.
Solve geometrical problems using side and angle properties of equilateral, isosceles and right-angled triangles and special quadrilaterals.
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).
