Year 3


The pupils are working on a broad curriculum in mathematics including: place value; addition and subtraction; multiplication and division; fractions; measurement; geometry and statistics. Their Homework Booklets support all the areas below. They are learning their 3, 4, 6 and 8 times tables.


Number - number and place value

Pupils will learn to count from 0 in multiples of 4, 8, 50 and 100 and find 10 or 100 more or less than a given number. They will recognise the place value of each digit in a 3-digit number (100s, 10s, 1s) and compare and order numbers up to 1,000. Pupils will read and write numbers up to 1,000 in numerals and in words and solve number problems and practical problems involving these ideas.


Number - addition and subtraction

Pupils will be adding and subtracting numbers mentally, including:

  • a three-digit number and 1s
  • a three-digit number and 10s
  • a three-digit number and 100s

They will be learning to add and subtract numbers with up to 3 digits, using formal written methods of columnar addition and subtraction. They will be estimating the answer to a calculation and using inverse operations to check answers. Pupils will solve problems, including missing number problems, using number facts, place value, and addition and subtraction.


Number - multiplication and division

In Year 3, pupils will recall and use multiplication and division facts for the 3, 4, 6 and 8 multiplication tables. They will calculate mathematical statements for multiplication and division using mental and written methods. Pupils will solve problems, including missing number problems.


Number - fractions

Pupils will count up and down in tenths; recognise that tenths arise from dividing an object into 10 equal parts and in dividing one-digit numbers or quantities by 10. They will learn to recognise, find and write fractions of a set of objects: unit fractions and non-unit fractions with small denominators. They will use diagrams and find equivalent fractions. 



In measurement, pupils will measure, compare, add/subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml). They will measure the perimeter of simple 2-D shapes. In money they will add and subtract amounts of money to give change, using both £ and p in practical contexts. For time, they will tell and write the time from an analogue clock. They will estimate and read time with increasing accuracy to the nearest minute. They will learn the number of seconds in a minute and the number of days in each month, year and leap year. 


Geometry - properties of shapes

Pupils will draw 2-D shapes and construct 3-D shapes. They will recognise angles as a property of shape or a description of a turn. They will identify right angles and identify whether angles are greater than or less than a right angle. They will begin to identify horizontal and vertical lines and pairs of perpendicular and parallel lines.



Pupils will interpret and present data using bar charts, pictograms and tables. They will solve mathematical problems relating to the data.
