Maths in Year 3


In Year 3, we place a big focus on developing efficiency in mathematical skills. As with English, we continue to build on the work from Infants to ensure children become confident mathematicians.


Year 3 end of year Maths expectations:


Number and Place Value

Count from 0 in multiples of 100 – e.g. 100, 200, 300, 400…

Count from 0 in multiples of 4, 8 and 50 – e.g. 4, 8, 12…

Recognise the place value of each digit in a three-digit number (hundreds, tens, ones)  - e.g. 231 is 2 hundreds, 3 tens and 1 one.

Read and write numbers up to 1000 in numerals and in words  - e.g. 123 = one hundred and twenty threee

Identify, represent and estimate numbers to 1000 using different representations and partitioning in different ways  - e.g. draw diagrams, number sentences etc.

Compare and order numbers up to 1000  - e.g. 231 < 987, 231 is smaller than 987

Solve number problems and practical problems with number and place value from the Year 3 curriculum

Round whole numbers up to 100 to the nearest 10  - e.g. 29 to the nearest 10 is 30.


Addition, Subtractions, Multiplication and Division (Calculations)

Add 1s, 10s and 100s to a 3 digit numbers

Subtract 1s, 10s and 100s from a 3 digit number

Solve problems including missing number problems, using place value and more complex addition and subtraction

Solve calculation problems involving multiplication and division, including missing number problems, simple positive integer scaling and simple correspondence problems in which n objects are connected to m objects

Know my tables for 3, 4 and 8 and their division facts

Add numbers with up to 3 digits using a written method (column method)

Subtract numbers with up to 3 digits using a written method (column method)

Multiply two-digit numbers by one-digit numbers, using written methods (column method)

Estimate the answer to a calculation and use inverse operations to check answers



Find a fraction of an amount such as 1/6 of 24

Find a fraction of an amount such as 4/6 of 24

Count up and down in 10ths

Understand that 10ths come from dividing an object by 10

Recognise and draw equivalent fractions

Compare and order fractions by their size

Add and subtract fractions with the same denominator within one whole for example 5/7 + 1/7 = 6/7 

Solve problems that involve fractions 



Know the number of seconds in a minute and the number of days in each month, year and leap year

Record measurements using mixed units, e.g.1 kg 200 g

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 

Tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks 

Measure the perimeter of simple 2-D shapes 

Compare durations of events for example to calculate the time taken by particular events or tasks 

Add and subtract amounts of money to give change, recording £ and p separately

Measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml) 


Geometry (Shape, Space and Direction)

Draw 2-D shapes with straight sides measured in cm

Make 3-D shapes using modelling materials 

Identify horizontal and vertical lines and pairs of perpendicular and parallel lines 

Describe 2-D shapes using accurate language, including lengths of lines and angles greater or less than a right angle

Recognise 3-D shapes in different orientations and describe them 

Identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn 

Recognise angles as a property of shape or a description of a turn 

Mark a given square on a grid, e.g. B3 


Statistics (Data Handling)

Interpret bar charts, pictograms and tables

Present data in bar charts, pictograms and tables

Solve problems with one or two steps using scaled bar charts, pictograms and tables
