If I understand what you have written correctly then:

Tacks 4 + 8 = 12 in base 10 but we have a '5' in the Tacks column - so to get a '5' we need to 'carry' a bundle of '7' which must be how many tacks are in a tick

DS has not done anything other than base 10. Is it worth confusing him with "non base 10" addition and subtraction at this stage for 11 plus? I guess not.
