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.
