Thank you for your enlightenment.
My child has DSA offers for RI HCI and NUSH. Which school would you recommend? Do you regret coming to NUSH?
Thank you.

RE: Q&A - PSLE Math
tianzhu:
Alternatively, you can use algebra.Maha Bodhi P6 Prelim 2010: Paper 2: Q16. Tom and Jerry shared a box of marbles. If Tom was given 10 fewer marbles, Jerry would have five times as many marbles as Tom. If Tom was given 10 more marbles, he would have Ā½ as many marbles as Jerry. What percentage of the marbles did Tom receive? [5 marks][Answer given: 25%]
Hi VC
Have you tried this question?
Could you get the same answer as given in the WS?
You may use MD.
Before
Tom -------1u+10
Jerry -------5 units
After
Tom ------- 1u+10+10
Jerry ------- 2units+40
3 units ------40
1unit ------40/3
Tom ------- 40/3+10 ----- 70/3
Jerry -------200/3
Total number of marbles ------- 200/3+70/3 --------90
Tom/Total ---------70/3/90*100 ------- 25 25/27% (25 and 25/27%)
Best wishes
---------------------------------------------------------------------------------
Let t and j represent the number of marbles Tom and Jerry received respectively.
j+10=5*(t-10)
=5t-50
-----------------------
Therefore, we have statement 1:
j=5t-60
-----------------------
t+10=(j-10) * 1/2
t+10=j/2 - 10/2
t+10=j/2 - 5
----------------------
Statement 2:
t=j/2-15
----------------------
Since we know what 't' is in terms of j,
Therefore we can replace the 't' in statement 1
in terms of 'j'.
We have:
j=5(j/2-15)-60
j= 5j/2 - 75-60
j=5j/2 - 135
---------------------
We bring all numbers to one side of the equation:
5j/2 - j = 135
Get rid of the '/2' by multiplying BOTH sides of the equation by 2:
5j-2j=270
3j=270
j=90
If Tom was given 10 fewer marbles, Jerry would have five times as many marbles as Tom.
j+10=5(t-10)
100=5(t-10)
t=30
30/(90+30)=30/120=25%
Note: the PSLE teachers are known to be stingy and MAY penalize you for this: 30/120=25%
The safest way is: (30*100%)/(120*100%)=25% -
RE: All About GEP
TwaTau:
not quite. my son's class sort of \"pressurize\" the teachers to tell them what are needed the previous day so their school bags are rather light (around an inch stack of paper), unless they need to bring their files.The trouble is they don't pack their bag, and not having it available when the school needs it, spells trouble for them. So the Kiasu mentality kicks in and everything goes into the bag, :slapshead:
Also find that ge students' bags are very disorganized because of so much worksheets. to make matters worse, the daily works takes up 10%. -
RE: Primary Science Olympiad
vlim:
Thanks, and that's correct. My son did not participate and thought he could this year... until he found out it was for p5 students.Congratulate to your son!
the 2010 Singapore primary science olympaid which is organised by NUSHU was over. Not all students get the chance to take part as I think the participating school will select 5 students to participate in the first round..unlike NMOS and RMSO, students who are keen can take part... -

3rd internationally or locally? My son was 4th internationally. and 3rd nationally. it was a bit frustrating actually, watching my son and his classmates trying to solve the questions, and getting it wrong.PettyLittle:
seems like this is the 1st year we're having this prog in S'pore (correct me if i'm wrong)...understand that some schools have started this since the beginning of the year...Can anyone share some feedback? I jus received a letter for my ds to start in Term 3...quite confused now, not sure if ds can cope with additional load..
No. I was in the programme last year and it is quite useful and interesting. My school also came in 3rd for the competition though I was not selected to take part in the competition. I guess it helped many of my friends in DSA with the certificates. :idea: They went by our SA2 marks and I did miserably. :oops: It is a fun programme with a lot of hands-on as mentioned before. I got to spend a lot of time with my friends(quite a handful of us were in the programme) and it was relaxing. Time is a factor though, it takes up a lot of time and it may even clash with tution and enrichment. He probably won't be stressed but may be worn out. Best he does not go for other classes after it. :roll: All in all, it is an unique experience and if all other factors are taken care of, I strongly feel you should not deprive your DS of such an independant learning experience. :celebrate: -
RE: 2010 DSA(Direct School Admission)
wonderm:
huh? by \"someone\", you mean his classmate? Influenced by friends, very possible! But \"paid him\"? how much must that be for your son to change his school choice? unimaginable!
Probably just the slight motivation my son needs to change to NUSHS, to create a WIN-WIN situation. I feel my self that NUSHS will suit him better, but it's too far... -
RE: Hwa Chong Institution (High School)
powershengyang:
I am from HCI personally and have not heard of any propaganda messages about NUSHS at all.[/quote]Ah, well, seems to be an isolated coincident then. It is probably because of the bond between those that is going for NUSHS that make it seem as if it has popular support. Highly likely that this all originated from one influential person and wanted classmates on his side. NOTE: DS is not that person. Or maybe that's just a joke. After all the day to decide is weeks away
No, not exactly true. The accelerated syllabus and the module courses is what that interest my son most. And some other very influential pupils, as I suspect, are leading the fight for NUSHS. Young people their age are incredibly vulnerable to such techniques, as they view themselves as \"grown-ups\" and don't really care for elders' advice and are young and indecisive enough to fall for the techniques, making the society of the class largely power-based. Fortunately, my son does not fall under any of the above categories.Guthix:
[quote=\"powershengyang\"]
Really, i thought propaganda was only between HCI and RI, have not heard of any propaganda concerning NUSHS yet. HCI and RI are strongly against each other as they compete for the best \"A\" level results each year, dont know why your child told you about NUSHS being in the equation as well. -
RE: Impersonation!
limlim:
when I first showed my DS the KSP, he was into everything... he seemed to be referencing with a book called \"Physcology Demystified\"
just curious.. what stuff in KSP can attract young kids ar..? which section does your child normally visit or is hooked to?Sun_2010:
DD is hooked too. Yesterday she was on her ipod surfing KSP, sigh!
She told me it was too tempting to resist and so gave up her ipod for safe custody till PSLE is over. Atleast on the home PC, I can keep an eye over her ...
Bet she will read this too -
RE: Impersonation!
limlim:
Not really true. My son managed to hack my password today morning. i suspect he posted something under my name. Sigh... I'm such a techno fool. btw. it'll be nice if we can check what we have posted.
Oh.. then you should be glad that she is pro-active in her studies mah..Sun_2010:
It started off with the PSLE Maths questions since Maths is her fav. I intorduced her to it. :stupid:
Then into science, english , DSA etc.
Now she browses thru other sections too - anything to get away from books i say. In fact i reward her with KSP time - \" finish paper and u get 15 mins of KSP\"
btw, we maintain our separate identities online ....
And I suspect that most KSP topics would be boring to kids too..
The only high risk section have been placed under lock and key :evil:
so there is actually very little risk to let them wonder around.. -
RE: Impersonation!
mommyellen:
no, tat doesn't work. if ur kid is meticulous enough, she take note to delete history. you can try to find a program or program it yourself something that can download the history separately onto something else. (Note: My son walk by just now and wrote that)My daughter has been very mischievous...:
Today I was using her iMac to serve the net (I'm using my old Windows XP now) because my dh wanted to load in some softwares and I saw her history. And it showed that she came here to KSP and posed as a parent... I was so shocked I called her over.
OK, it wasnt so bad. She didnt post anything, she was just checking out the site... I hope she hasnt seen my posts ( :!: ).
Btw, I am not revealing her username as it would be very embarrassing :oops: for my little daughter.
Anyway, here's just a piece of advice for all parents out there, watch what your child is doing on the net. And you could frequently look at your child's computer history to see if he/she is going to any funny sites on the net.
