Venn Diagrams : Can't to kids homework tonight
 

Help from SN maths gurus please :D

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 :D :D

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 :D

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 :D

Cheers in advance

Shaun

9-2-5-4-6-1-7-3-8 for 11

Dunno about rules, I left school 20 years ago!!

Brilliant :D :D :D

Google was no help with this one !!

Now drawing 6 in a line circles on my 20th sheet of paper used so far LOL

Cheers

Shaun

I used powerpoint cos I'm a geek :D

What's the digit range for 6?

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 :D

How can powerpoint help ??

Thanks again

Shaun (left school in 1978)

You can't have more than 3 circles in a Venn diagram.

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

But not circles, they would have to be ellipses or other shapes.

Sudoko ? :D

Thanks all :D

Oooops.... I should have mentioned that the school have called them "circle puzzles" and not Venn Diagrams :)

Thanks for the wikipedia link.......I didn't know that the said Mr Venn was born in Hull like me, bit of a saddo really then LOL

Hank, can you send me the your powerpoint stuff to shaunwhitehead:aol.com

Cheers


Shaun

How confusig is this!!! :eek2:

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 :lol1:

DK1

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 :D

Cheers

Shaun

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 :D

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.

Is it me or have you ballsed up on the 4 circles one? 2-5-1 doesnt add up to 10 :wonder:

Dave

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 :D

Hopefully the teacher will enlighten me :)

Shaun

Gotcha, but the first circle doesnt add to 10!!!! LOL I might not be a genius but I can add up ;)

Would this be of use in later life? There may be a point of course but I would need it to be explained.

Les

Just, midlife is proving its of use in later life so you can teach it to the younger ones ;)

I have never heard of these before and now I hope none of mine ever come home with them :o

All seems a bit complicated, if we struggle then how can a 9 year old do them? :wonder:

Well done to your son too! :luxhello: :D

Now I see it all.

Les :D

Just a quick update...... this wasn't mentioned at school at all apart from the teacher saying that Lucy's dad (me) had got a star :D

I guess she had set the wrong homework LOL

Lets pass on the star to Hank :D

Shaun

I'll take that! :D

I now have several guys in the office, including one with advanced degrees in maths working on the 6 circles, if no success we'll put the grid to work!

Left it alone for a few weeks and went back to it today...

Six circles....

11 - 3 - 9 - 1 - 6 - 7 - 5 - 2 - 8 - 4 - 10

:D

3+9+1 = 13 :confused:

Awwwwww pooop!
