Year 5 Measurement The metric system takes centre stage in the new Year 5 Measurement Programme of Study, emphasising the importance of converting between different units of metric measures. By the end of Year 5 children should know the following relationships between metric units: 1 kilometre      = 1 000 metres 1 metre    = 100 centimetres or 1 000 millimetres 1 centimetre = 10 millimetres 1 kilogram     = 1 000 grams 1 litre        = 1 000 millilitres They should know the equivalent of one half, one quarter, three quarters, one tenth and one hundredth of 1 km,  1 m,  1 kg,  1 litre respectively in smaller units. know that  one hundredth of a litre is 10 millilitres. They should be able to write larger units in terms of smaller units. e.g. 7.5 km is 7 500 m 2.58 m is 258 cm 6 cm is 60 mm. Whilst most measurement that children come across will be metric, in the real world the old Imperial system is still used, especially with regard to road measurement and vehicle speeds. This means that children will also be expected to understand and work with both systems, including equivalence between metric and imperial, something which many will find a step in the wrong direction. Children should know common imperial unit conversions to metric, including: The mile is about 1 600m, a little more than 1.5km The pint is about 570 ml, a little more than half a litre The gallon is a little less than five litres. Calculating and comparing the areas of squares and rectangles is also highlighted using standard units such as square centimetres and square metres. It is suggested that measures questions can be expressed algebraically (e.g. 4 + 2b = 20 for a rectangle of sides 2 cm and b cm and perimeter of 20 cm). Children will calculate the area of shapes from scale drawings using given measurements. The full Programme of Study is shown below: Measurement Pupils should be taught to: •    convert between different units of metric measure (e.g. kilometre and metre; centimetre and metre; centimetre and millimetre; gram and kilogram; litre and millilitre) •    understand and use equivalences between metric units and common imperial units such as inches, pounds and pints •    measure and calculate the perimeter of composite rectilinear shapes in centimetres and metres •    calculate and compare the area of squares and rectangles including using standard units, square centimetres  and square metres and estimate the area of irregular shapes •    estimate volume (e.g. using 1 cm cube blocks to build cubes and cuboids) and capacity (e.g. using water) •    solve problems involving converting between units of time •    use all four operations to solve problems involving measure (e.g. length, mass, volume, money) using decimal notation including scaling.
