Why are parents nowadays so kiasu..and doesn't the grading scheme follow a bell curve? So why is there a cause for worry if the paper is truly that difficult..?
i still cannot get 68sweets
Alamak why move here..
I also found the standard to be a little high...
But if everyone does badly, you just have to be better to get a better grade/score
Every single year confirm got parent make a mountain out of a molehill one
english not good just say la, top student got top in english comprehension anot ?
u canot compre the qn no matter how good maths is also die.
2cents. dun flame me la. wthhhh
then later if paper easy
parents ask why all a* nvr get * insert mark* =.=
stupid right?

Solution
Let Jim's Ratio of Sweets to Chocolates be x
Ratio therefore would be: x : 7x
Let Ken's Ratio of Sweets to Chocolates be Y
Ratio therefore would be: y: 4y
since Jim ate 12 sweets, Ken Ate none.
(x+12)=y ---(1)
therefore 2y = Ken's total sweets
Since Jim did not eat any of his chocolates, Ken ate 18.
(4y+18)= 7x ---(2)
from (1)
x= y-12
sub into (2)
4y+18 = 7(y-12)
4y+18=7y-84
102=3y
y = 34
2y =68 (solved)

Hi Yihao,
I believe that it is usual practice for PSLE to have one or two very difficult questions which are meant to separate the most outstanding students from the others. These questions will usually requires students to think out of the box, or consists of lower secondary-level mathematics such as algebra.
I hope this tell you why 1 or 2 questions which requires algebra appears in some of the years for PSLE.
Cheers.
My Sis finish leh~
gosh! she ish smart!!!!!!!!!!!!!!!!

a) like u ?
b) unlike u ?
choose 1 . xD
I just don't understand, year after year parents make a big fuss with the paper being too difficult.
I think they have to come to terms with the fact that either
a) Paper difficult, everyone is taking the same paper
b) The student is "buay kan" lor.
Should watch Mr.Brown's podcast on PSLE questions being too difficult; epic
Pretty disappointed with myself. BTW the last 2 questions are 4 marks each and not 5 marks.
Honestly, I think that making the last 1/2 questions the toughest is a good idea.
It separates the best students and critical thinkers from a pool of good students.
Getting an A* should not be a problem if you score well for all the questions except for the tough ones.
Cheers!
i nvr study also can get A already. good student should be able to get A* la...
just 15more marks righT?

halo mister.
i also nvr complain about the qn what, why is that u said directed at me
Ken
S I__I
C I__I__I__I__I 18 I
Jim
S I__I 12 I
C I__I__I__I__I__I__I__I
In Jim's model, 1 unit + 12 sweets = 1/2 of Ken's original number of sweets = 1 unit in Ken's model. Therefore, Ken's model will become: (since chocolates is 4 times sweets + 18)
S I__I 12 I
C I__I 12 I__I 12 I__I 12 I__I 12 I 18 I
Similarly, 4 units + 18 chocolates in Ken's model is equivalent to the 7 units of chocolates in Jim's model, which is 1/2 of Jim's original number of chocolates.
From the model above,
4 units + (4X12) + 18 = 7 units
4 units + 66 = 7 units
3 units = 66
1 unit = 22
1/2 of Ken's sweets = 1 unit + 12
= 22 + 12
= 34
Ken's number of sweets = 34 X 2 = 68

Hi Yi Hao,
I am sorry if you find my reply to have been offensive, but please be assured that my only intention is to let you understand the reason behind why algebra only appears in some of the years for PSLE.
Cheers.

As long as you done your best, no need be disappointed

NONO , relax, its nth offensive la.

MOE should have made it clear to parents that the scores will be moderated according to the cohort's performance. the intro of calculators had surely reduced the chances of careless mistake n the students would have saved time calculating answer. that is probably why qns are set to make them think more to compensate. also, it can better differentiate the better ones from the best. tell me, if there is maybe 40 pupils getting 100%, who can tell who's better? with influx of foreign students, surely the standard has to be raised some way
Got this question from somewhere else on the internet:
6/14 of the chairs in a hall are in rows of 13. Half of the chairs are in rows of 7. There are 112 more chairs in rows of 7. The rest of the chairs are stacked up. Find the total number of chairs. (5marks)
Turns out the answer can be easily obtained to be 1568. But then if it is so how can 6/14 of the chairs be rearranged into rows of 13*? I used to do very badly in primary school math because of these extra details that 'tricks' or confuses the student by having them consider extra details that most of the time adds to the confusion! Oh well, no point complaining about PSLE as I got over it aeons ago (there are better things in life than getting good grades, or a well paid job), and the current P6 kids and their parents should too.
*Turns out it wouldn't be a whole number.
I think people need to look at the questions from the viewpoint of a 12 year old kid.
As adults, we can easily rationalise and solve primary school maths questions even if they were tricky because most of us have (hopefully) taken maths up till O levels or higher. Our problem solving skills and mathematical abilities will definitely be higher and more advanced than those of the Primary 6 kid.
Kids will still be kids, regardless of how smart or mature they may seem for their age.
Faced with an exam which they thought they would do well but instead got whacked will hit their morale and confidence hard. It's just the normal way kids will react in these situations.

honestly, i dun think primary school kids know how to apply algebra to the qn =)
A P5 Math Olympiad student is taught how to solve maths questions using simultaneous equations (elimination and substitution methods), form algebraic equation and solve them using all the different solving for x methods by her teacher.
Teachers are very kiasu now.
