To not make DD correct her school work

[MayhapMayhem]

DS has dyscalculia and we have been spending the past few weeks trying to convince him that 43 = 34 etc

Teacher has returned some of DD's school work (Year below DS) and told her to do corrections. It's maths, her favourite subject and on the first page she has been marked 2/9. I haven't told her yet as she's going to be upset.

What has been marked wrong
47=28
34=12 (this has been corrected to 43=28)
63=18
16=6
45=20
27=14
36=18

In each case the teacher wanted the sum written the "other" way round I.e. 74, 61 etc.

On the next page
6+6=6*2=12 is marked as wrong.

AIBU to not make her "correct" it or should I tell her to write = b*a at the end of each sum?

Sorry, instructions: Write the addition first and then the multiplication. You will need to search for the items in the picture above.

In Scotland the multiplication tables are taught the other way around, so
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8 etc.

I really don’t think you can say that 3 lots of 4 has to be written 3 x 4. It is exactly the same conceptually as 4, repeated 3 times which you can write as 4 x 3.

The ordering of 3 and 4 is just a convention. England does it one way, Scotland the other.

The teacher is wrong to mark those correct answers as wrong.
Later in Maths, it doesn’t matter how you got to the right answer so long as you get to the right answer!
So it does nothing but confuse children to say an answer is ‘wrong’ simply because they arrived at the right answer through a different method.

I think it’s cos she wants number of groups x number in each group. Which I think makes 5, 8, 13 and 16 correct. 12 isn’t if that’s what she wants.

Possibly she doesn’t know herself and is just following the scheme but having to think about it. I had to think about which was the ‘right’ way to put the numbers.

But 5) there are four bunches of 5 flowers so in my logic it should be 5+5+5+5=20

I agree with you about 5+5+5+5. It looks to me like your child is confused, probably because of the 3 x 4 or 4 x 3 thing not being written the way that makes sense to them, and simultaneously the teacher has gone cross-eyed with all the marking they’re doing so missed the mistake. Or maybe they’re trying to mark while being distracted by small children or something.

Ex maths teacher here.

I don't think DD is confused. She originally only wrote the multiplication. I made her go back and do the addition and she probably did it without looking at the picture. I've told her she has to re-do the whole second page.

Teacher doesn't have small kids!

Ah yes, that makes sense. She would have to be really tied in knots to write it as 4+4+4+4+4 otherwise.

Well it looks like your DD swapped the order halfway round but then again so did the teacher when marking so I'd just leave them, as long as they're correct.

Since questions 3 and 8 are basically inverse, I don't understand why one is marked wrong and one marked correct?
