In the last post, we looked at multiplying and dividing by 10, 100 and 1000. We are now going to look at how children can apply this skill to help them with other mental maths questions which will arise in the arithmetic test and during grid method for multiplication.
In the next part of the mental maths series, we are going to look at multiplying and dividing by 10, 100 and 1000. Your child will come across these type of questions in their arithmetic tests but it is also a really important skill to help them answer other mental maths questions and to use within grid method for multiplication.
Children tend to start this in Year 4 and Year 5 and the aim is for children to be able to do this mentally. However, a good starting point is using a place value chart.
There are some rules to remember:
There are three formal written methods for multiplication used in Key Stage 2 : grid method, short multiplication and long multiplication.
What does multiplication looks like in each year group?
