  • Great idea for a resource but they all need to be corrected! At the moment, if you follow the steps you end up with the wrong answer. For example at the moment it is...:47 - 23 = ___
    40 - 20 = 20 and then 20 - 3 = 17! The answer should be 24
    Either you need to change the subtract tens number so it matches the number sentence in the box (so it would be 47 - 20 =) or remove the arrow so you are not carrying you answer forward and you are just subtracting the ones. From a teaching point of view, I think changing the subtract tens number would be better! Hope that all makes sense, it's difficult to describe!

  • There is a mistake on set 1 cards. It says 58 - 30 = but then underneath it says 116 - 50.

    Like that it fits in with the NC objectives with the language used. :)

  • 'units' not 'ones'?
    Also 'subtract the tens' but then 'add the ones?????'
    Nice idea though!
