Teaching subtraction as the inverse of addition

Discussion in 'Primary' started by KarrieGem, Jul 9, 2011.

  1. Hi everyone,
    I teach a top set year 1 class for numeracy and just wondering if anyone has any tips for helping children to understand that subtraction is the inverse of addition, just not sure quite how to teach it, any suggestions welcome,

    Children will find subtraction harder than addition and division harder than multiplication unless they are taught together so children can clearly see the relationship between them.
    Also important to use a range of language for the operations, particularly subtraction.
    Maybe choose a context linked to your topic or story and provide addition and subtraction problems for children to solve using appropriate resources.
    What do the children know and understand already? Use this to help them make links to new learning. So if they know some addition facts such as bonds for 5 or 10, this might be a good place to start.
    Hope this gives you some ideas to get started.
