Welcome to

Rush Green Primary School



The following  page outlines the order in which subtraction is taught in our school. There are many different methods and so the following pages should provide some clarity as to the methods taught in our school.


Using Tangible Resources

When children first begin to carry out subtraction, they are encouraged to use resources such as cubes, small toys etc. to help them to understand the processes involved. Click on the link below to explore how we teach children to learn subtraction this way.



Using Number Squares

Number squares play an important role in the teaching of subtraction. In our school they are introduced to the children formally in Year 1 and children will use them regularly throughout Year 2.





Partitioning involves splitting numbers up into more manageable chunks which can then be used when calculating. This is introduce to the children in Year 1, when they partition numbers into 'Tens' and 'Units.' This method of calculation is essential for helping calculate both mentally and when performing formal written calculations and is used all the way up to Year 6. Want to find out more?

Mental Methods

Being able to calculate mentally is an essential skill which the children will need to use in their future lives. It is important that these skills are embedded before the children can move on to learning formal written methods of calculation. Click on the link below for some of the many strategies which the children are taught whilst in our school.



Formal and Informal Written Methods of Subtraction

From Year 3, children are taught how to set out subtraction calculations, leading to the traditional columnar method which parents are likely to be familiar with. Click on the image below to find out the steps children learn to set out their calculations.
