Measurement
KS1MA-Y2-D005
Pupils choose and use appropriate standard units to estimate and measure length, mass, temperature and capacity; use symbols for money; solve practical money problems; and tell the time to five minutes.
National Curriculum context
Measurement in Year 2 moves decisively from informal and non-standard approaches to the accurate use of standard units. Pupils use standard units of measurement with increasing accuracy, using their knowledge of the number system, and use appropriate language, recording using standard abbreviations (m, cm, kg, g, °C, l, ml). Comparing measures includes simple multiples such as 'half as high' and 'twice as wide', connecting measurement to multiplicative reasoning and fractions. Pupils become fluent in telling the time on analogue clocks and recording it — progressing from the hour and half past of Year 1 to five-minute intervals and quarter-past/quarter-to. In money, pupils become fluent in counting and recognising coins, read and say amounts of money confidently, and use the symbols £ and p accurately, recording pounds and pence separately. They solve simple problems in practical contexts involving addition and subtraction of money of the same unit, including giving change. The domain connects strongly to number knowledge (number bonds, addition/subtraction) and develops the practical mathematical literacy pupils will use throughout their lives.

Measuring Length, Mass, Capacity, Temperature, and Money
Mathematics Practical ApplicationPedagogical rationale
Y2 measurement introduces standard units, which is a significant conceptual leap: pupils must understand that we need agreed units so everyone measures the same way. Reading scales is a cross-cutting skill that applies to rulers, kitchen scales, measuring jugs, and thermometers. Money work connects number, place value, and measurement: 1 pound = 100 pence mirrors the base-10 number system. All measurement work should be practical and hands-on, with pupils recording and comparing their results.

Measuring with standard units: length, mass, temperature and capacity
skill AI FacilitatedMA-Y2-C014
Year 2 requires pupils to choose and use appropriate standard units to measure with increasing accuracy, using rulers (m/cm), weighing scales (kg/g), thermometers (°C), and measuring vessels (litres/ml). This represents a significant step from the introduction of measuring tools in Year 1 to accurate, independent measurement with standard notation. Mastery means pupils can select the appropriate unit and tool for a given measurement, measure to the nearest appropriate unit, read scales accurately, and record using standard abbreviations.
Teaching guidance
Provide ample practical measurement experience with real objects and instruments. Teach reading scales explicitly — scales with different intervals require careful counting. Estimate before measuring to develop number sense about quantities. Discuss appropriate choice of unit: centimetres for a pencil, metres for a classroom; grams for a biscuit, kilograms for a child. Record using standard abbreviations from the start (m, cm, kg, g, °C, l, ml). The non-statutory guidance specifies that comparing measures includes simple multiples such as 'half as high' and 'twice as wide', connecting measurement to multiplication and fractions.
Common misconceptions
Reading scales that do not label every division causes errors — pupils count individual marks rather than working out the interval between labelled marks. When measuring length, pupils misalign the start of the ruler with the start of the object. Confusing kg with g and l with ml leads to errors of a factor of 1000. Pupils may not read a thermometer correctly because temperature scales include negative numbers below zero.
Difficulty levels
Measuring the length of objects using a ruler, aligning the object with 0 and reading the end mark, for objects shorter than 30 cm.
Example task
Measure the length of this pencil using a ruler. Start at 0.
Model response: The pencil is 12 cm long.
Choosing and using appropriate standard units (m/cm, kg/g, °C, l/ml) and reading scales with labelled divisions.
Example task
Would you measure the length of the classroom in cm or m? Read the temperature on this thermometer. [Shows 18°C]
Model response: I would use metres for the classroom because it is very long. The thermometer shows 18°C.
Measuring length, mass, temperature and capacity with standard units, reading scales where not every division is labelled.
Example task
This weighing scale is labelled 0, 100g, 200g, 300g with 5 marks between each label. What does each small mark represent? Read the mass shown. [Arrow points to 3rd mark after 200g]
Model response: Each small mark represents 20g. The mass is 260g.
CPA Stages
concrete
Children measure objects using real measuring instruments: rulers for length (starting from 0), balance scales with standard weights for mass, thermometers for temperature, and measuring jugs for capacity. They choose the correct instrument and unit for each measurement.
Transition: Child selects the correct instrument for each measurement type, aligns the ruler from 0, reads scales by counting marked intervals, and records results with correct units.
pictorial
Children read scales on diagrams of rulers, weighing scales, thermometers and measuring jugs. They practise interpreting scales where not every mark is labelled, working out the value of each division. They record measurements using standard abbreviations in tables.
Transition: Child works out the value of each interval on a scale before reading, correctly reads unlabelled divisions, and records using m, cm, kg, g, °C, l, ml.
abstract
Children estimate measurements before measuring, choose appropriate units (cm vs m, g vs kg, ml vs l), compare measurements using >, < and =, and solve problems involving multiples ('half as high', 'twice as wide').
Transition: Child estimates measurements to within a reasonable range, selects the appropriate unit, records with correct abbreviations, and compares measurements using subtraction and symbols.

Access barriers (1)
Measuring with standard units requires precise physical manipulation: reading scales, positioning rulers at zero, pouring liquid to a line. Children with dyspraxia may understand the concept of measurement but be unable to position tools accurately.
Money: using £ and p symbols, making amounts, giving change
skill AI FacilitatedMA-Y2-C015
In Year 2, pupils move beyond recognising coins (Year 1) to using the £ and p symbols accurately, combining coins to make specified amounts, finding different coin combinations for the same total, and solving simple addition and subtraction problems involving money including giving change. Mastery means pupils can work confidently with money in practical contexts, record amounts accurately using £ and p notation (recorded separately, e.g. £1 and 35p, not £1.35 which uses decimal notation introduced later), and calculate change mentally.
Teaching guidance
Use real or realistic plastic coins and notes. Practise 'making amounts' by selecting coins to reach a target total. Explore how many different combinations of coins can make, say, 20p (reinforcing understanding that value matters, not the number of coins). For change, use the 'shopkeeper's method' of counting up from the cost to the amount paid: if something costs 37p and you pay 50p, count up 37 → 40 (3p) → 50 (10p), so change is 13p. The curriculum specifies recording pounds and pence separately at this stage; do not introduce decimal £ notation (£1.35) as this comes later.
Common misconceptions
Pupils mix up £ and p symbols and may write amounts like £37p or confuse 37p with £37. When counting coins to make an amount, pupils sometimes count the number of coins rather than their values. Calculating change by subtraction is much harder than counting up, so most pupils benefit from the counting-up strategy initially. Finding all possible coin combinations requires systematic thinking that many pupils do not apply spontaneously.
Difficulty levels
Recognising all UK coins and notes by name and value, and using the £ and p symbols with whole amounts.
Example task
This costs 35p. Write the price using the p symbol. This costs 2 pounds. Write it using the £ symbol.
Model response: 35p. £2.
Making amounts using different combinations of coins and finding how many different ways to make a given amount.
Example task
Make 30p using exactly 4 coins. Can you find a different way?
Model response: 20p + 5p + 3p + 2p = 30p. Another way: 10p + 10p + 5p + 5p = 30p.
Solving money problems involving making amounts, adding prices and giving change.
Example task
A toy costs 45p. You pay with a 50p coin. How much change do you get?
Model response: 50p – 45p = 5p. I get 5p change.
CPA Stages
concrete
Children handle real or realistic plastic coins and notes, practising naming values and using the £ and p symbols. They sort coins by denomination and make given amounts by selecting coins from a collection. Shopkeeper role-play provides a meaningful context for combining and exchanging.
Transition: Child selects coins to make amounts up to £1 and writes prices using £ or p symbols correctly (never mixing them: not £35p), and finds at least two different coin combinations for the same amount.
pictorial
Children draw coins to make given amounts, record different combinations in tables, and use bar models to solve money addition and subtraction problems. They practise counting up from a price to the amount paid to calculate change.
Transition: Child draws coin combinations and uses bar models to solve money problems including giving change, counting up from the price to the amount paid.
abstract
Children solve money problems mentally using addition and subtraction skills, recording amounts with correct symbols. They calculate change by counting up or subtracting, and find different coin combinations systematically.
Transition: Child calculates prices, totals and change mentally using efficient strategies (counting up, using known bonds), recording amounts with correct £ and p symbols.

Telling the time to five minutes and quarter past/to
skill AI FacilitatedMA-Y2-C016
Year 2 extends clock reading from the hour and half past (Year 1) to five-minute intervals, including quarter past and quarter to the hour. Pupils read and write the time and draw clock hands to show given times. Mastery means pupils can read any time that is a multiple of five minutes on an analogue clock, distinguish between quarter past and quarter to, and know the number of minutes in an hour (60) and the number of hours in a day (24).
Teaching guidance
Connect the five-minute intervals to counting in fives (curriculum connections): the 12 positions of the minute hand on a clock are each 5 minutes apart, and counting in fives from 0 (at 12) gives the minute values (5 at the 1, 10 at the 2... 30 at the 6, etc.). The non-statutory guidance explicitly connects the 5 times table to the divisions on the clock face. Use geared demonstration clocks so movements of the minute hand are shown to move the hour hand proportionally. Quarter past connects to the quarter turn concept from Year 1 geometry; quarter to connects to three-quarter turn. Introduce written time recording (e.g. '3:25' alongside 'twenty-five past three').
Common misconceptions
Pupils confuse quarter past and quarter to — 'quarter to 4' means the minute hand is at 9 (showing 45 minutes past, or 15 minutes to 4) but pupils may read the 9 as referring to the hour and say 9 o'clock. Reading times between the hour and half past (e.g. 20 past 3) is generally easier than times between half past and the next hour (e.g. 20 to 4) because 'to' requires pupils to count backwards from the hour. The hour hand position between two numbers is consistently a source of error.
Difficulty levels
Reading o'clock and half past times on an analogue clock (consolidating Year 1).
Example task
What time does this clock show? [Shows 9 o'clock, then half past 2]
Model response: 9 o'clock. Half past 2.
Reading times to five-minute intervals using the minute hand position: 5 past, 10 past, quarter past, 20 past, 25 past, half past.
Example task
What time does this clock show? [Minute hand at 3, hour hand between 7 and 8]
Model response: Quarter past 7. The minute hand is at 3, which means 15 minutes past.
Reading any time to five minutes on an analogue clock, including 'to' times (quarter to, 10 to, 5 to), and drawing clock hands.
Example task
What time does this clock show? [10 minutes to 6] Draw a clock showing quarter to 9.
Model response: 10 to 6. The minute hand is at 10, which means 50 minutes past or 10 minutes to the next hour. [Draws minute hand at 9, hour hand just before 9]
CPA Stages
concrete
Children use geared demonstration clocks and individual clock-face manipulatives to set and read times. The gearing shows how the minute hand movement drives the hour hand proportionally. They connect the 5 times table to the minute positions: the 1 on the clock means 5 minutes, the 2 means 10 minutes, the 3 means 15 minutes (quarter past).
Transition: Child sets a clock manipulative to any five-minute time including quarter past, half past and quarter to, and reads times set by someone else, explaining the minute hand position using the 5 times table.
pictorial
Children read times from drawn clock faces and draw hands on blank clock faces to show given times. They practise both 'past' and 'to' times, connecting quarter past and quarter to to the fraction vocabulary from geometry (quarter turn).
Transition: Child reads any five-minute time from a drawn clock face including 'to' times, and draws both hands in the correct positions (hour hand between numbers for non-o'clock times).
abstract
Children tell the time to five minutes on analogue clocks without manipulatives, write times in standard notation (e.g. 3:25), and know that there are 60 minutes in an hour and 24 hours in a day.
Transition: Child reads any five-minute time from an analogue clock and writes it in standard notation, knows 60 minutes = 1 hour and 24 hours = 1 day, and calculates simple time intervals.
