Calculating with Money and Giving Change
Children learn to combine coins, calculate totals in pounds or pence, and work out change in everyday shopping problems.
Y1.M.3 recognise and know the value of different denominations of coins and notes
Y2.M.3 recognise and use symbols for pounds (£) and pence (p); combine amounts to make a particular value
Y2.M.4 find different combinations of coins that equal the same amounts of money
Y2.M.5 solve simple problems in a practical context involving addition and subtraction of money of the same unit, including giving change
Y3.M.3 add and subtract amounts of money to give change, using both £ and p in practical contexts
In Year 2, children use the symbols £ and p to solve simple addition and subtraction problems using money of the same unit. Working within 100p or £100, they combine coins to make a particular value, find different combinations of coins that equal the same amount, and calculate how much change is due from purchases.
A common mistake occurs when children count the number of coins rather than their actual values, such as thinking four 5p coins are worth more than one 50p coin. Children also frequently struggle when calculating change, often adding the cost of the item to the money paid instead of subtracting to find the difference.
Practice tasks use everyday store scenarios to make these ideas concrete. Children work through activities such as Shopping and change, select Which coins to pay with, and check whether a set of coins Is there enough money to buy an item. Other activities ask pupils to calculate How much do several items cost or find calculation errors in Change: fix the mistake.
Calculating Time and Comparing Durations
Children learn to work out how much time has passed, compare durations of events, and convert hours into minutes using the knowledge that an hour has 60 minutes.
Y2.M.6 compare and sequence intervals of time
Y2.M.8 know the number of minutes in an hour and the number of hours in a day.
Y3.M.7 compare durations of events [for example to calculate the time taken by particular events or tasks].
Y1.M.1.d time [for example, quicker, slower, earlier, later]
In Year 2, children build on reading clock times to sequence events and calculate simple intervals of time. Using the core facts that there are 60 minutes in an hour and 24 hours in a day, they convert whole hours into minutes, determine how long an activity lasts, and find start times by working backward from a finish time.
A common hurdle is confusing the base-10 number system with units of time. Children often incorrectly assume there are 100 minutes in an hour rather than 60, leading to mistakes when converting hours to minutes or calculating elapsed time. They can also mix up the duration of an event with the clock time at which it ended.
Practice tasks apply these concepts through everyday routines. Children order daily events in The day plan: put the times in order, solve word problems to determine Time duration (how long?) or How many minutes have passed?, and compare activities directly to find How much longer one lasted than the other.
Reading a thermometer in degrees Celsius
Children learn to read temperatures to the nearest degree Celsius on a thermometer scale and compare different readings.
Y2.M.1 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
In Year 2, children learn to measure temperature to the nearest unit using standard degrees Celsius (°C). They read vertical scales where values count up from zero, applying their knowledge of counting in steps of 1, 2, 5, or 10 to identify where the liquid line stops.
A frequent error occurs when children misinterpret unlabelled divisions on the scale. For example, on a thermometer marked in tens with halfway dashes for fives, a child may assume every tick mark counts by ones, reading 25°C as 21°C. Others occasionally read down from the top of the tube rather than counting up from the base.
Worksheet tasks present clear thermometer diagrams where children write down the temperature shown or choose the correct reading from multiple choices. Exercises also include deciding whether a given reading is true or false, spotting mistakes on a misread scale, identifying which thermometer shows the warmer reading, and calculating how many degrees a temperature has risen.
Measuring Length in mm, cm and m
Children learn to read measurements from rulers and convert lengths between metres, centimetres and millimetres.
Y2.M.1 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
Y3.M.1 measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)
Y1.M.2.a lengths and heights
At this stage, children measure lengths and heights using standard units, working within numbers up to 100. Using rulers, they read lengths to the nearest unit and explore the relationships between units, converting between metres and centimetres as well as centimetres and millimetres.
A common error occurs when measuring with a ruler: children often align an object with the physical edge of the plastic or the number 1 instead of starting cleanly at the 0 mark. When converting, they also frequently mix up the scales, treating a metre as 10 centimetres rather than 100, or forgetting that 1 centimetre contains 10 millimetres.
Practical tasks include reading the length of an illustrated object aligned with a ruler, converting metres and centimetres to centimetres, and converting centimetres and millimetres to millimetres. Children also reinforce these conversions by spotting errors in fix the mistake tasks, answering true-or-false prompts, and choosing the correct value from multiple-choice options.
Telling the Time to Five Minutes
Children learn to read and write the time on an analogue clock to five minutes, including quarter past and quarter to the hour.
Y1.M.6 tell the time to the hour and half past the hour and draw the hands on a clock face to show these times.
Y2.M.7 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
Y3.M.4 tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks
Y3.M.5 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
Y4.M.5 read, write and convert time between analogue and digital 12-and 24-hour clocks
Y1.M.2.d time (hours, minutes, seconds)
In Year 2, children build on reading hours and half hours by learning to tell and write the time to five minutes on an analogue clock. They read times such as twenty past four or ten to eight, with a particular focus on key landmarks like quarter past and quarter to the hour, and practice drawing the hands accurately on clock faces.
A common mistake happens when the minute hand points to the left side of the clock face (the "to" side). Because the hour hand has crept close to the next number, children often read the upcoming hour too early—reading twenty to six as twenty to seven, or confusing whether to count minutes past or minutes to the hour. They may also swap the roles of the long minute hand and short hour hand.
Worksheet tasks ask pupils to look at a clock dial and choose or write the correct time, decide whether a stated time is true or false, and spot and correct mistakes in clock readings. Children also practise calculating how many minutes remain until the full hour and comparing two clock faces to identify which one shows the earlier time.
Measuring Capacity in Litres and Half-Litres
Children learn to measure, compare, and calculate liquid capacity using standard units such as litres and half-litres to solve everyday problems.
Y2.M.1 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
Y3.M.1 measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)
Y1.M.2.c capacity and volume
In Year 2, children learn to choose and use standard units—specifically litres and millilitres—to measure, estimate, and compare capacity using measuring vessels. Working with simple quantities, they combine whole litres and half-litre amounts, calculate how much liquid is needed to fill a container, and compare which vessel holds more.
A common mistake occurs when children confuse the number of containers with the total volume of liquid. For example, when working with half-litre bottles, a child might count each bottle as one whole litre, or assume that two half-litre bottles hold more liquid than a single 1-litre bottle simply because there are more physical containers.
Practice tasks use visual containers to reinforce these concepts. Children answer questions like How many litres from that many half-litre bottles, work out How many more to fill it, find How much more one container holds than the other, and calculate How many bottles will the juice fill.
Comparing and Ordering Lengths and Weights
Children learn to compare and order objects by length and weight, finding which is longest or lightest and calculating how much longer one item is than another.
Y2.M.2 compare and order lengths, mass, volume/capacity and record the results using >, < and =
Y1.M.1.a lengths and heights [for example, long/short, longer/shorter, tall/short, double/half]
Y1.M.1.b mass/weight [for example, heavy/light, heavier than, lighter than]
Y1.M.1.c capacity and volume [for example, full/empty, more than, less than, half, half full, quarter]
In Year 2, children build on everyday comparison words to compare and order measurements such as length and mass. They order multiple items from lightest to heaviest or find the longest object, and they record comparisons using the >, <, and = symbols. Children also work out the difference between two lengths to state exactly how much longer one object is than another.
A common error happens when children are asked how much longer an object is. Instead of subtracting the shorter measurement from the longer one to find the difference, pupils often simply read off and report the total length of the longer item.
Practice tasks use visual measurement prompts. Children may see a set of items and be asked to complete Which one is the longest or Put them in order from lightest. Other tasks present paired measurements, such as How much longer is the ribbon, where children solve multiple-choice questions or decide whether a statement about the difference in length is true or false.
Measuring Mass in Kilograms and Grams
Children learn to choose and use grams and kilograms to measure mass, convert between units, and calculate how much is needed to complete a whole kilogram.
Y2.M.1 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
Y3.M.1 measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)
Y1.M.2.b mass/weight
In Year 2, children learn to choose and use standard units of mass—kilograms (kg) and grams (g)—to measure and compare weight. They learn that lighter items are weighed in grams while heavier loads are measured in kilograms, and they explore how smaller units combine to make a whole kilogram.
A common difficulty arises when children treat the numbers on a scale without considering the unit of measurement. For instance, when finding how many grams are missing to make a full kilogram, children frequently attempt to count up to 10 or 100 instead of 1,000 grams, confusing standard base-ten facts with the metric conversion.
Worksheet tasks give children structured practice with mass through activities such as:
- Deciding whether statements converting kilograms to smaller units are true or false.
- Selecting the correct answer to complete a conversion from kilograms to grams.
- Calculating how many grams are missing to reach a full kilogram.
- Solving simple division problems to find how many portions a packaged mass makes.
