Measure accurately using appropriate units, interpret and compare

Core learning in mathematics by strand

Measure accurately using appropriate units, interpret and compare scales Children learn to:

Foundation Stage

Use language such as ‘greater’, ‘smaller, ‘heavier’ or ‘lighter’ to compare quantities

Use everyday language related to time; order and sequence familiar events and measure short periods of time with a non-standard unit

Year 1

Estimate, measure, weigh and compare objects, choosing and using suitable uniform non-standard or standard units and measuring instruments, e.g. a lever balance, metre stick or measuring jug

Use vocabulary related to time; order days of the week and months; read the time to the hour and half hour

Year 2

Estimate, compare and measure lengths, masses and capacities using standard units (m, cm, kg, litre) and suitable measuring instruments

Read the numbered divisions on a scale, and interpret the divisions between them, e.g. on a scale from 0 to 25 with intervals of 1 shown but only the divisions 0, 5, 10, 15 and 20 numbered; use a ruler to draw and measure lines to the nearest centimetre

Use units of time (seconds, minutes, hours, days) and know the relationships between them; read the time to the quarter hour and identify time intervals, including those that cross the hour boundary

Year 3

Know the relationships between kilometres and metres, metres and centimetres, kilograms and grams, litres and millilitres; choose and use appropriate units to estimate, measure, and record measurements

Read, to the nearest division and half-division, scales that are numbered or partially numbered; use the information to measure and draw to a suitable degree of accuracy

Read the time on a 12-hour digital clock and to the nearest five minutes on an analogue clock; calculate time intervals and find start or end times for a given time interval

Year 4

Use standard metric units and their abbreviations when estimating, measuring and recording length, mass and capacity; know the meaning of kilo, centi and milli and, where appropriate, use decimal notation to record measurements, e.g. 1.3m or 0.6kg

Interpret intervals and divisions on partially numbered scales and record readings accurately, where appropriate to the nearest tenth of a unit

Core learning in mathematics by strand

Draw rectangles and measure and calculate their perimeters, find the area of rectilinear shapes drawn on a square grid by counting squares

Read time to the nearest minute; use am, pm and 12-hour clock notation; calculate time intervals from clocks and timetables

Year 5

Read, use and record standard metric units to estimate and measure length, mass and capacity; convert larger to smaller units using decimals to one place, e.g. change 2.6kg to 2600g

Estimate measurements of length, mass and capacity to a required degree of accuracy, e.g. the nearest centimetre; interpret a reading that lies between two unnumbered divisions on a scale

Draw and measure lines to the nearest millimetre; measure and calculate the perimeter of regular and irregular polygons; use the formula for the area of a rectangle to calculate its area

Read timetables and time using 24-hour clock notation; use a calendar to calculate time intervals

Year 6

Use standard metric units of measure and convert between units using decimals to two places notation, e.g. change 2.75 litres to 2750ml, or vice versa

Measure and calculate using imperials units still in everyday use; know their approximate equivalent metric values

Read scales and record results to a required degree of accuracy, recognising that the measurement made is approximate

Calculate the perimeter and area of rectilinear shapes; estimate the area of an irregular shape by counting squares

Year 6 progression to Year 7

Convert between related metric units using decimals to three places, e.g. convert 1375mm to 1.375m, or vice versa

Read and interpret scales on a range of measuring instruments; compare readings on different scales, e.g. when using different instruments

Calculate the area of right-angled triangles given the lengths of the two perpendicular sides, and the volume and surface area of cubes and cuboids
