# Anyone good with maths? Homework help needed!

ok, so i'm obviously having a blonde moment not being able to do year 6 maths homework, but can anyone give me an idea of an easy how to solve this? Pic in next post

I'm sure homework wasn't this hard when I was in primary school!

what about the second one, is there any way of doing without guessing? (thanks to herewego1234 for getting one way of doing it!)

Does anyone else think this is hard for a year 6 (10 year old)?

Yes, definitely - and it's certainly hard for this 68-year-old!

I can't fathom how to approach the first problem logically.

Nor can I see any method for answering the second problem "how many ways of making 200".

My grandson is 9, and his homework isn't this difficult.

I have much sympathy with a headteacher somewhere who has stopped homework altogether. He says the advantages of setting homework are dubious, and certainly not worth the aggravation for pupils and parents.

Anyway, what is your child's school up to, setting homework during school holidays? Kids need their rest and relaxation as much as adult workers.

Our son brought some home and it was blatantly WRONG...

It was a reproduced sheet rather like the above from an online supply of worksheets.

I did some research and found others reporting similar problems, but the teacher had just printed it off and sent it out...

He's 10 now and Very good at maths, but his homework was not nearly challenging enough untill we complained...

He does LOVE maths, so he didn't mind

Other stuff has been harder than I remember for sure...

usually they do quite a few of these with teachers, modelling how to work it out before they expect the children to be able to get to the stage of answering correctly.

You would be surprised at what children can do.

she gets quite a few like this, but usually i can see a logical way of working them out, this time either my brain went blank or it was just a case of guessing numbers

easy to give an answer after someone has already given it

and if ktdd has an iq above 167 then she may be better than me

I couldn't see any way that you could easily work out a formula! Trial and error only for me. It gave my old grey cells a bit of a work out and I guess that's the general idea! I have no idea what I could do when I was 6 but I doubt it was stuff like this - we had weekly mental arithmetic tests!

The only way to do it without guessing would be formulaically, and even using this you would just end up using trial and error ultimately.

Substituting each of the values for letters:

w x

y z

which leads to:

10w+x + 10w+y + 10y+z + 10x+z = 200.

====>

20w + 11x + 11y +2z = 200

or

10w +5.5(x+y) + z = 100.

with the obvious constraints of w =/ x =/ y =/ z and they are all 1-9.

From that, all that comes out obviously is that x and y are both even or both odd, but after that it's down to trial and error I'm afraid (or a mathematical calculator!)

So, yes, I think this is too hard for a 10 year old.
