Anyone help with what method this could possibly be?

[secretlemondedrinker]

Dd is in Y3 and has recently moved to a new school, in her new school it seems they use a new method for partitioning, according to dd, which she says she doesn't understand at all, which I have to say sounds odd as she was easily partitioning 5 digit numbers at her old school, she says it is a collum method and I can't think what it could possibly be? and dd is not able to explain it very well so I'm a bit stuck as to how to help her, I'm going to ask the teacher next week but thought in the meantime I would ask here.
TIA (I appreciate its a bit of a tough task)

It could be 234
+ 567

                 11    ( 4+7)
                 90    ( 30 +60)
               700    ( 200 +500)

              801

( which probably won't come out right at all!)

Is it this?

Expanded Column Method (taught from year 3 or 4 onwards)

327+255 = 582

327 +255 500 + 70 + 12 582

That should be

327
+255
500
70
12
=582

I give up all the tens and units should be underneath each other in columns but it won't come out right when I press post

In my class we are currently doing partitioning to add. So 567+231 is

500 + 60 + 7
200 + 30 + 1
__
700 + 90 + 8 = 798

We would then move on to:

567+
231

8
90
700
_
798

(Bl00dy lining up does NOT work! Have to imagine units under units, tens under tens ...

Thanks everyone.
She pointed at Thornrose 's post and said that's it and she understands it now, although I have to say I'm a bit as to why she didn't understand it in the first place as it Isn't all that different to the method used at the old school and pretty straight forward.
What sort of nc level would this be? I guess if it's year 3 or 4 then about a 3c/3b?
