What is she learning~??

[LilMatchGirlInVictorianSqualor]

My 8 yr old DD is doing some homework.
She has to add up some double figured numbers as part of a game but doesn't know how to do sums!!!
How on earth can she get to year 3 without being taught sums?
Surely they are still supposed to learn to add up hundreds, tens and units??

Did you not know before know she didnt know how to do sums?

Her homework has always been single numbers before.
I'm flabbergasted.
She said that everything they add up is written in a sentence, not as a table.

If she's used to adding horizontally this may help...e.g.
27+36= 20+30+7+6= 50+13=(50+10+3)=63
May not need the step in brackets.

Do they not do tens and units anymore then?
I still use tens and units now if I'm adding things up!

They don't start vertical sums until Year 4. Makes it hard for old-fashioned parents to help with homework! The way infin did it is how mine have been taught.

dd is year 3 and does it both ways !

Yes...they do use tens and units but horizontally as in the example I gave. As KateF says, vertical addition is usually introduced in Y4 (although can be summer term of Y3) but will not initially be the tradtional layout...tens and units are still separated.
27
36

13
50

63

Left out so digits line up!!!!

They learn something called partitioning first where they split the numbers up into tens and units first. e.g. 25= 20+5
They do that for both the numbers in the sum then add them up separately

e.g.
25+34

20+30=50
3+4= 7

57

The reason for this is that they learn what the digits in each number represent. They move onto the tradidional column method later on (year 4 I think)
This also helps to develop better mental skills.

my dd is doing vertical sums in P3, which is equivalent of year 2 (Scotland). She has grasped the concept of "carry the 1", but is struggling a bit with the idea of carrying 2 if the column adds up to more than 20 .

Children who are ready for it might learn the column method in Year 3.
A whole range of strategies are taught nowadays, so that children can choose one that's appropriate for the calculation in hand. Mental strategies are vitally important.

Ah, so have I just messed her up by teaching her the vertical way?

Not really. She may or may not understand it, but at least she'll recognise it when she meets it "officially" at school.
