Clearly I need to go back to school! Why is this wrong?

DD came home with a workbook to show us. She asked why it is wrong. Honestly, I'm stumped. Someone explain!

She hasn't matched the dice to the circles

"Draw the spots on the domino, colour in the tiles"

I think, looking at exercise 2, it's a simple addition. It doesn't matter how you spread the dots across the two rows, as long as the total matches the number of dots on the domino as well and they both reflect the number in the final column for each?

Interested in this thread?

How old is your daughter? I presume well under ten years old.
If that is the case, good for the school giving the pupils things like this to do in addition to the usual subjects. They will become accustomed to such tests and even find them fun after a while, doesn't matter about getting bits wrong now, she will improve.

That sort of thing is now part of the 11+ and so many primary schools don't bother with it.

So why are they wrong ShmooBooMoo?

ShmooBooMoo · 30/08/2018 16:19

Although, this wouldn't explain why the answers in exercise 1 are marked incorrect! Confused

it looks like, where possible, the teacher wants the dots displayed across the rows to match the dominoes, but that goes out of the window when there is a six!

It's maths Hmm The point is why is it wrong because as far as I can see it isn't. And she's going to be demoralised pretty quickly, not to mention utterly confused, if all her correct work is marked wrong!

I think I may have sussed it. Only shade in the ones she doesn't need. So for example there are 5 blank dots on one side and say 6 blank dots on the other. To show 4 on the right she needs to shade in 1 then show 5 on the left she needs to shade in 1. She only shades in what she doesn't need. Then blank ones represent what the amount she does need. Hope I've made it clear. Ask the teacher so you can explain it to your daughter.

It's a really stupid and poorly designed exercise, that's what's wrong.

I've asked if the technical people can move picture 2, with the printed example, to the OP. Don't know if it's possible.

Yes. This.

argentino · 30/08/2018 16:31

What a weird exercise.

CottonSock · 30/08/2018 16:33

I think there should be six dots each side?

^ this and I don't see how it teaches maths. Convoluted problem solving, maybe, but not maths.

ShmooBooMoo · 30/08/2018 16:36

i think the teacher wants the arrangement of dots on the domino image to match the arrangement of dots over the two rows so in OP's original example 5/1 = / =6.
The next three are marked wrong because they should look like this:
4/4 = / =8
4/1=/ =5
5/2=/ =7
The last one the teacher marked as being right because, as there is no sixth circle in the row, she expects the child to make the first circle of the second row into the sixth one of the first.

It's totally stupid as far as I can see! It's confusing and not helpful!

InterstellarSleepingElla · 30/08/2018 16:36

Ok, not sure if this has been mentioned/suggested but could it be an exercise of "5+a=b". So each domino face should be 5 on on face and then the remaining number on the opposite face? The circles to colour should be just the total - no pattern as such for the circles?

InterstellarSleepingElla · 30/08/2018 16:38

Oh just seen the second image so that rules out my suggestion.

ShmooBooMoo · 30/08/2018 16:38

Still, this theory wouldn't explain why the teacher marked the last answer in the second exercise as correct. I am wondering if the teacher gets it/ actually knows what s/he wants! Confused

That's what I first thought, but the last one (6+3) is marked correct and if you follow that logic it should be wrong (5+4).

ShmooBooMoo · 30/08/2018 16:40

Yes, CottonSock but that wouldn't explain why the last answer in exercise 2 is marked correct... This is starting to really hurt Confused

TheVonTrappFamilySwingers · 30/08/2018 16:43

The last one should also be marked wrong, not right. Looks like a confusing piece though.

ShmooBooMoo · 30/08/2018 16:48

That's a good question, Silent Grin

PattiStanger · 30/08/2018 17:02

I'll be interested to hear how the teacher explains what was required and how it fits with the example

DGRossetti · 30/08/2018 17:06

I wonder if it's a misprint/mistake ? Not impossible.

MrsRubyMonday · 30/08/2018 17:12

I would think that the child should have used max of five on the left, and then the remainder on the right to add up to the total. She did the colouring wrong for the first three as she didn't allow for the two sides therefore they are marked wrong, as previous posters have said.

However, for the last one she used a six. As an adult, I would have used five as I have a max of five dots to colour for that side of the domino. As it doesn't specifically state that she cant use six, and she's coloured the first six and then the rest needed, I think the teacher has used some flexibility to mark that one correct, as she has technically coloured the correct combination if the dots were divided differently. If it had said use a max of five on the left it would be wrong. I would think the teacher is trying to encourage that she thought outside the box to come up with an answer.
