Firsly, I think do you have a issue with deciding who is the 100%? That is usually on eof the common problem.Maybe you can send me ur solution then I can help u diagnose why u arrive at $740


Secondly, remember that Ratio, percentage and fraction can be used to solve a problem sum despite the question being a % question.

Solution (Ratio method) which is what I would usually use for this type of questions.


A : S
120 : 100
6 : 5
x 2 x 2
J : A
100 : 80
5 : 4
x 3 x 3

J : A : S
15 : 12 : 10

37 units --> 2220
1 unit --> 2220 ÷ 37
--> 60
12 units --> 60 x 12
--> $720

[quote=\"is_me_lblue\"]Hi,

I am stuck again.

Amos'salary is 20% more than Steve's but 20% less than Joe's. If their total salary is $2220,find Amos's salary.

I always get the answer of 740 but answer given is 720.

Thank you

Small,

Thank you, I not so good in math so have to learn together with my son.

Hi,

Plese refer my revised solution. Apologies for the typo error in my ealier post

Just practise n practise. I used to do my ten years series like 3 times before any major exams.


Even now , if u look at children who score well, they practise many problem sums until they are able to know what method to use for diff types of question.

Some r able to visualize the model in their mind they do not need to draw them at all.

Interesting thing is many children spend so much time drawing model as their teacher require them to look like a piece of art work, using ruler and all.

Just make sure the model is big enough to fit in information and for resizing, should not take more than a minute.

I failed maths in p6 sa1. By PSLE I also scored an A*.

From then on, maths for o,a level n uni, all A.

So don't give up .

[quote=\"kitty2\"]Sorry to bring up this topic again .
atutor2001,this's my friend's son problem and they've been wasting money on all the tutors.Most of them have no patient to teach or know how to handle him.My friend is in distress & helpless as he's already P5 and not much time left to brush up for P6.

Anyone can help :? ,thanks

Hi Kitty2

I agree with spunky's suggestions. Patience and doing our best to get improvement in his results to boost interest and confidence seems the only solution. Shower praise no matter how little the improvement may be (but not advisable to entice with material incentives).

Tutor will not have the time needed to make such kids remember. Only parents can. So parents need to follow up on what has been thought by the teachers/tutors.

There is also this funny thing, I called \"enlightenment\", which Chinese called \"kai qiao\" whereby the kid suddenly can understand all the concepts and most importantly can also remember them. Some kids found enlightenment pretty late - there is kid I know who \"see light\" in math only after SA1 in P6 - very worrisome for the parents. After that he was even aiming for A* after doing very well in Prelim.

Just to share my experience.

Regards

There is a reason for everything . The masses will always make us feel inferior . Don't we r blessed chosen few

kaitlynangelica:

Hi all,

I am the one who started the thread. But I'd like to say that I have learnt to be content and happy with just one child. I have learnt to count my blessings instead of comparing with others how come some can have 3 or 4 kids and God has only given me one. In fact, now that my dd is in P2, I have come to thank God that I have only one. Its really no joke to have to jaga the child all the time. So much homework, CCA's, tuition etc etc. I used to feel terribly inferior about just having one child but God has been kind and blessed me with peace to realise that he knows best for me.

Thing is sometimes, it helps to just give the child the same set of problem sum again. Let him/ her learn the skill of solving a certain type of problem.


Get the child to explain it to you again each time. After a few times with a similar problem, the child will actually improve. Do try it,

I used to do that when I was given the weakest lot of pupils. They always end up doing well by PSLE.

Sometimes new problem compounded with weak English means the child is handling 2 weakness at the same time.

Doing the same questions a few times and explaining to u lets the child at least master the Maths skills required, without the English problem.

When the child improves and gets more confident with repeated success , then you give your child another set of problem sums with different skill requirement.

Patience Pays

[quote=\"NIEtrainedTEACHER\"] .....
The important thing to take note is that, we should let the child develop their skill step by step. Sad to say the duration may be slower than what we may like but the reward would be greater..... :oops:

Not sure if you have encountered kids who, by nature, just has no \"logic sense\". After spending hours explaining the logic, they finally understood it and we thought hurray, he/she finally understand - only to find that 1 day later, everything is forgotten and we need to explain again and again. When the question is re-phrased, the poor kid will also not be able to apply the same logic.

The cycle goes on and the time needed to get them to understand becomes longer and longer as the problem sum becomes more difficult. Before we realise, the poor kid has already reached P6 and the final result is obivous.

My guess is that about 50% of those kids who do badly for math are in this category. It is a real heartache.

The remaining 50% are either just plain lazy or poor in English. Kids in the lazy group would not be bothered to think when the problem gets too complex and just simply give up. The English Problem group doesn't even understand the question. Teaching in steps cannot help the lazy group to overcome the need to think or the English Problem group to understand the language used when many problem steps are combined into 1 complex question.

I'm no Tiger mama though. If he can score Band 2, I'm happy...Band 1 would be a bonus.

Many conduct supp. Classes because every other school or teacher is doing it. I am not against them if the teacher really plans his/her after sch program at least ur child is learning effectively.

I have seen many teachers in staff room just printing w/s half and hour b4 the after school program starts just to occupy the class.

Check what is going on through ur child's work then decide if it is worth staying back.
U will be surprise ur child might h a more productive time at home doing his own revision w ur supervision.

I did think of taking my son out of one class. Need to check with him seriously what his teacher is doing for Chinese. Need more time to revise Comprehension OE with him. Maybe English as well. Just wondering what are the teachers doing with students during supp lessons.
2 days taken out of the week for these lessons...if take son out, will he be missing out anything ?[/quote]As an ex teacher, I really urge u to check on child's work in sch. What I told u abt what teachers do are v real. There are very dedicated ones (god bless them) but few r left as most r too involved w sch projects they r expected to do. then u decide what actions to take.

Teachers r human they get tired too so teaching is affected, but ranking system has made teachin only a small part of performance ranking in sch.

teh_oh:

1 - 3/8 - 1/8 = ____


For the above type of math questions, will marks be deducted if the child did not reduce the answer to '1/2' after getting '4/8'?
Thanks.

no marks should be deducted unless the question specifies that answer must be in the simplest form.

However, as a good habit, teach the child to reduce at all times especially simple fractions like 4/8

I agree with u.


I told u to be selective about what u choose for your child

My question to u is this : can ur child take it if u expect her to finish all the exam papers and also the assessment books u bought?


If she can without any stress, then fine, go ahead and pile it on her.

Many teachers and parents make the same mistake: The more the merrier as every other parent is doing it.

But if u plan properly, a few goes a long long way. Resist the temptation to buy so many assessment books.

Solution:

Use some of the papers in place of assessment books.

Best part is u save money buying assessment books, questions are set by teachers for the top school exam papers and thirdly, u do not waste paper
