  • A great step-by-step visual resource to help teach column subtraction.

  • It should carry ten over not one! Could be confusing...what a shame.

    • Hi AnnieSherrard,

      Thank you for your resource comment on the Twinkl website.

      The reason that we have written '1', rather than '10', is because this follows the examples shown in the National Curriculum. These would still be called 'tens', but written as '1', which then joins with the digit it is next to. E.g. carrying a ten to join with a 5, to make '15'.

      I hope you have a lovely day! : )
