Measurements

SUBJECT: Maths - Measurements

Year

Key Concepts (Statutory Requirements)

Year 1

 

 

 

 

  • compare, describe and solve practical problems for:

                    - lengths and heights [for example, long/short, longer/shorter, tall/short, double/half]

                    -  mass/weight [for example, heavy/light, heavier than, lighter than]

                    - capacity and volume [for example, full/empty, more than, less than, half, half full, quarter]

                    - time [for example, quicker, slower, earlier, later]

  • measure and begin to record the following:
  • lengths and heights
  • mass/weight
  • capacity and volume
  • time (hours, minutes, seconds)
  • recognise and know the value of different denominations of coins and notes
  • sequence events in chronological order using language [for example, before and after, next, first, today, yesterday, tomorrow, morning, afternoon and evening]
  • recognise and use language relating to dates, including days of the week, weeks, months and years
  • tell the time to the hour and half past the hour and draw the hands on a clock face to show these times.

 

Year 2

 

 

  • choose and use appropriate standard units to estimate and measure length/height in any direction (m/cm); mass (kg/g); temperature (°C); capacity (litres/ml) to the nearest appropriate unit, using rulers, scales, thermometers and measuring vessels
  • compare and order lengths, mass, volume/capacity and record the results using >, < and =
  • recognise and use symbols for pounds (£) and pence (p); combine amounts to make a particular value
  • find different combinations of coins that equal the same amounts of money
  • solve simple problems in a practical context involving addition and subtraction of money of the same unit, including giving change
  • compare and sequence intervals of time
  • tell and write the time to five minutes, including quarter past/to the hour and draw the hands on a clock face to show these times
  • know the number of minutes in an hour and the number of hours in a day.

 

Year 3

 

  • measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)
  • measure the perimeter of simple 2-D shapes
  • add and subtract amounts of money to give change, using both £ and p in practical contexts
  • tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks
  • estimate and read time with increasing accuracy to the nearest minute; record and compare time in terms of seconds, minutes and hours; use vocabulary such as o’clock, a.m./p.m., morning, afternoon, noon and midnight
  • know the number of seconds in a minute and the number of days in each month, year and leap year
  • compare durations of events [for example to calculate the time taken by particular events or tasks].

Year 4

 

  • Convert between different units of measure [for example, kilometre to metre; hour to minute]
  • measure and calculate the perimeter of a rectilinear figure (including squares) in centimetres and metres
  • find the area of rectilinear shapes by counting squares
  • estimate, compare and calculate different measures, including money in pounds and pence

 

Year 5

 

 

  • convert between different units of metric measure (for example, kilometre and metre; centimetre and metre; centimetre and millimetre; gram and kilogram; litre and millilitre)
  • understand and use approximate 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 rectangles (including squares), and including using standard units, square centimetres (cm2) and square metres (m2) and estimate the area of irregular shapes
  • estimate volume [for example, using 1 cm3 blocks to build cuboids (including cubes)] and capacity [for example, using water]
  • solve problems involving converting between units of time
  • use all four operations to solve problems involving measure [for example, length, mass, volume, money] using decimal notation, including scaling.

 

Year 6

 

  • solve problems involving the calculation and conversion of units of measure, using decimal notation up to three decimal places where appropriate
  • use, read, write and convert between standard units, converting measurements of length, mass, volume and time from a smaller unit of measure to a larger unit, and vice versa, using decimal notation to up to three decimal places
  • convert between miles and kilometres
  • recognise that shapes with the same areas can have different perimeters and vice versa
  • recognise when it is possible to use formulae for area and volume of shapes
  • calculate the area of parallelograms and triangles
  • calculate, estimate and compare volume of cubes and cuboids using standard units, including cubic centimetres (cm3) and cubic metres (m3), and extending to other units [for example, mm3 and km3].
