Venn Diagrams : Can't to kids homework tonight
Help from SN maths gurus please 
Tonights homework for the 9 year old is about adding using Venn Diagrams !!
I can't post a pic but imagine three circles in a line each intersecting the other, I have to put numbers in the 5 spaces (1-5) so the circles all add up to the same number
I have solved the 3 circle puzzle using 5 1 3 2 4 in the spaces from left to right adding up to 6
I have managed to solve 4 circles overlapping in a line using digits 1-7 adding up to 10 using 7 3 2 5 1 4 6
But for the life of me I can't work out the soulution to 5 circles using digits 1-9
Any idea's or even better is there a sort of "rule" I can follow as the number of circles increases
Cheers in advance
Shaun

range 1-11
I've been at this for the last hour, I've been trying to work out groups of 2 numbers which add up to the same as the one in the circle next door so that they can "share" a number.
I always start with the two biggest numbers at the end.
Why this has been set for a nine year old baffles me
How can powerpoint help ??
Thanks again

Typically, they have no more than 3, but you can have more. Venn diagram - Wikipedia, the free encyclopedia

How confusig is this!!! 
Best thing to do would be to go and ask the teacher about it tomorrow, if you understand it, you can help your child understand it without doing it IYKWIM
I refuse to do my daughter's homework, she's great in class yet lacks the concentration at home and is lazy, so I make her think and go on until she gets it and does it right

to be honest I don't think any amount of thinking on behalf of my daughter would have cracked this one LOL
I help with my kids homework but don't "do" it for them..my boy is leaving the same school this September with 5's in all SATS subjects

Sorry to interrupt...
Well I'm stumped and I'm a teacher! I expect (or hope) there is a much easier way of doing it that was explained in class! I'd ask the teacher too. Then can you tell us how to do it?!!!

Shaun, I just used it for the circles and numbers, easier to move around for trial and error and I forgot how to use a pencil in 1996
The 6 circles has got me beat so please post the solution when you get it!
I was always very good at maths at school/college but sometimes on a new subject, I'd need the answer to help the understanding and get to that moment where it clicks. So as long as they're helping the understanding, providing the actual answer shouldn't be a problem.
If they're just cutting and pasting off the internet, that's helping nobody.
Education should be about learning, not answers.

for the 4 circle puzzle
1st circle has 7+2
2nd circle has 3+2+5
3rd circle has 5+1+4
4th Circle has 4+6
That one only took me half an hour and four sheets of paper LOL
Not sure if homework is going to be marked today as it's sports day, well if the rain stops
Hopefully the teacher will enlighten me

All seems a bit complicated, if we struggle then how can a 9 year old do them?
Well done to your son too!
