Once children are familiar with the standard method of addition for 3 digits they can be introduced to addition of decimals. One of the best ways to do this is by adding money. On this page the first eight questions have been written out in the correct way, but the next seven will also need to be written out using the same method. The key here is to keep the decimal point in line as the numbers in later addition of decimals may not necessarily all have two digits after the decimal point. Also, don’t forget the £ sign in the answer.
