Place Value
In Year 4, before we begin any calculation work, the children need to gain an understanding of what each number in a four digit number represents. Children will use this knowledge to access more difficult concepts as the year progresses. You can find more information and practise this skill using the links below

Addition and Subtraction 

 

Children will use their strong understanding of place value to add and subtract two 4 digit numbers using exchanging. 

 

We use concrete resources to physically show the children why an exchange is needed. Please see the video below for video aimed at Key Stage 2 children and their parents. This shows how to add two 3-digit numbers together using Dienes. The calculation shown is 263 + 119. Made by St Helena's C of E Primary School, Willoughby, Lincolnshire, UK.

Some children may also need some additional support with number facts and quick addition and subtraction. Practicing these simple number facts at home is a great way to ensure your child feels confident in class during this topic! Please use the link below:
