Ds1's homework! Write these fractions as decimals. How do i explain to him how to do it?

[tortoise]

Not really sure how to do it myself! So how on earth do i explain to him in simple terms how to do it! He is 10 BTW.
Please help.

not a lot of help after half a bottle of wine and very little sleep

And now my spelling has gone too. maths i meant!

He will be learning long division by chunking

Really - it is so much easier than long division. He will have done lots of place value for years so will know that 0.1 is a 1 in the tenths column......

chunking ?????? isn't that about throwing pumpkins????

I didn't exactly mean long division where you go down hte page I meant write out bottom number as 8.00000000 until you get no remainders to carry....

The 10ths and 100ths are easy as you say, but how would you teach the 1/8ths one without saying there are 8 parts in a whole and that 1 part is 0.125, without doing the calculation 1/8 without dividing?????

chunking!!! I had to ask him to explian that and he completly lost me.

ok eighths

you have or think of your hundredths and decimals are in hundredths.....

he may know how to share by 8 by using halving
he should certainly know how to share by four by halving (half it then half it again). sharing by eight you just half it again

so you have you 100 100ths
half it 50/100
half it again (sharng by 4 so a quarter) 25/100
half it again (sharing by 8 so eighths)
12.5/100 so 0.125

toroise - will link you to a fab site...

look here ESPEICALly 4th and 5th blue link on main page. brill homework help for parents

I have to go to bed....but will check back in the morning (early!!!!) to see if I can be of help.

Email if you want - I don't have CAT.

Use popsycal2005
at yahoo dot co dot uk

Thanks, I will have a look at that and talk him through some bits in the morning. Not sure when i will be online because i'm on dial up at the moment!
(Has to do HW by Monday!)

Grrr can't open the file.

Tortoise. You need to save the file and then open in Microsoft wrks or other word processing program. It doesn't work if you use wordpad/notepad which is the default.

Open your word processor first and do file open....

HTH

Well, i am no closer to understang how to explain it to him. Should i leave it and speak to his teacher tomorrow? Or is that going to be leaving it too late?
Going offline for a bit now but will be back later.

Gosh, this is all so different to the way I was taught. Vaguely remember the faction x 100 over 1 system myself. So to turn 1/4 into a percentage you multiply it by 100/1.

1 100
x

4 1

Not sure the spacing will work when I press post, though. But four goes into 100 25 times so 1/4 = 25 per cent.

fraction

OMG. I'm skulking about on here. Dd is only yr4 atm. We've got this to come then .

Popsycal needs to write us a crib sheet I think.

am happy to do crib sheets
in fact i have dsome

tortoise
if he is really struggling i would tell teachrt.....needs to know if he really cant d it

He did some this morning using a calculater! (I didn't see that) He really doesn't seem to know what to do. He says they haven't done them at school.

In that case, I think you need to let him get them wrong and write a little note just saying you spent lots of time on it but realise that your way of doing it will not be the same as the methods used in schools today so were hesitant about showing him your way. Ask if the school has any 'numeracy evenings' where parents get shown methods.

FWIW - if I am sending homework home I always make sure that a) it is something we have been working on all week or b) revision of something that we have worked on previously or c) extends learning wher children have to apply what they have been learning.

I always send a parent sheet home if there is a likelihood that it contradicts methods that parents will have learned in school.....
