A very useful resource which shows and explains very clearly the concept of adding 10 and subtracting 1 to add 9. Thanks for sharing.

Hi - I thought this was lovely. Supported what I had just been teaching my class about how the digits change when adding. Thanks for making the effort on our behalf!
