Free subtraction worksheet: using the standard method (2)

Another maths worksheet from mathsblog.co.uk which shows the ‘standard’ method for subtraction. It is an excellent practice page at getting used to the method as it only deals with 2-digit numbers. Two points need to be made:

1. It is normally expected that 2-digit subtraction should be done ‘in your head’ and this page is only a beginning to learn the method for harder 3-digit, decimal etc. subtraction later.

2. All the questions here require ‘decomposition’ and there is a danger that a child comes to think that they always have to ‘decompose’ even when it is not necessary.
