Honestly I do not understand how such questions can differentiate a or a* students?

Or am I missing out something

Most kids will get 9 rolls without considering in depth the question, kids who get 10 rolls will put in more thought into the question.

Hence separating the A and A* students.

Doing well in PSLE maths is like a chess game, you must have a game plan but ready to change if the situation changes.

Heard that the ribbon question costs 2 marks, correct me if I am wrong, if is a 3-mark qn. Because if is a 3-marks qn, that's a lot !

Suppose there are two P6 students at PSLE : X and Y

Supose a student, X, had scored 89 marks (before reaching / attempting this ribbon qn) if this student X managed to get this ribbon qn correct, after analysis & working :-
Add back another 2 marks : Total, how much he get now ?

89+ 2 = 91, hit A*

So, student X scored A* (91 or higher), for Maths


But, suppose another student Y (also with 89 marks, initially) attempted same ribbon qn, but did not manage to get it correct, end up final score still 89+ Zero = 89

So, student Y scored A (89), not A *

Qn
Does this 2-mark PSLE ribbon qn set, help to differentiate students from a pool, to score A * vs A ?

Not really, but it can still determine the student's final grade, eventually.

How ?

Without ribbon qn present, initially -
both students X and Y would have ended up the same, at 89 marks. Both would have just scored A grade.


But, With ribbon qn, thrown in :
Student X finally scored A*

while Y remained at A.

Why ?

Because In any exam, every single mark counts.
It is up to students to read the question carefully, understand what the question really want, interpret the qn, analyse carefully, work out the steps, calculate each step carefully, show all working step-by-step

2 mark question can differentiate A or A* student? :scratchhead:

No...of course not. But a 2 mk qn can determine whether you get a A or A*...no? 😉

So what even if the question is ambiguous?

Simply taking 200 x 110 / 2500 = 8.8, round up to 9 is inadequate, and does not show any understanding of the mathematical concept. If you take 9 rolls and cut it up into 110 cm strips, you only get 198 strips of 110 cm and 9 strips of 80 cm. You do not get 200 strips of 110 cm and a strip of 500 cm as remainder.

In order to demonstrate understanding, the child must go further:

1 roll yields 2500 / 110 = 22 ribbons of 110 cm + 1 remainder of 80cm
9 rolls yields only 9 x 22 = 198 ribbons of 110 cm
2 more ribbons of 110 cm need to be made by joining 2 x 80cm ribbons with 2 x 30cm from the remainders.

I seriously doubt that many students who answered 9 would have put in those last necessary steps in the working. 😉
LOL!
You those stupid questions where they give you a larger piece of paper and ask you how many smaller pieces of square or whatever shapes you can cut out if it...yeah...you can actually tape those leftover bits together and make a few more of the smaller shape.

A star calibre gets an answer and know WHAT E NUMBER MEANS. But A calibre likely to be able to manipulate numbers based on what they have learnt n might not know what e number means thought they managed to get an answer.

From ext year e format has change n nn instead of kca, qn’s r based on authencity levels. Like it or not, expect more of this. For me I like it cos it makes number’s real n thus relevant in life.

Imagine…a man goes to a shop to buy A4 paper:

Man: uncle A4 paper 1 pack.
Uncle: nah ( passed him 2packs of A5 pack cos he happened to have more stock of A5 paper n willing to charge 2 A5 for lesser than 1 A4)
Man: uncle I want A4.
Uncle: 2 A5 pack n 1 A4 pack same what. Means u dunno if u join 2 A5 can get A4? Some more cheaper.
Man: but I want A4!
Uncle: nah I give u sticky tape free u go home join.
Man: but I need whole piece A4 cost I using for printer to print document!
Uncle: say early lah! Next time be clear of what u want then we don’t waste each other time.
Uncle: take out a pack of A4 paper finally.

Is e man being ambiguous of what he wants or e uncle being unreasonable?
U be e judge.

inxj:
These few years, many of these life skills questions appeared in the Maths paper.

Had been preparing my students for these types of questions and they have no problem solving it when this question came out.

Remember the $1 coins question 2 years back.
There might be more of these kind of questions in future.
Yes, u are right

Since that year when the $1 coin qn started to appear, subsequently in the next few batches, also got similar weird or unexpected \"out of the box\" qns appear during Psle, perhaps to sieve out / differentiate A* students, from A students in the common pool, for Maths.

I am just trying to give an alternative view on the question.


Ambiguity always open to more interpretation. Why do one want to leave it ambiguous in the first place?

slt:
I do not understand why so many experts come out and support that there is no ambiguity, this is a good question and seem to imply that this type of question should be further encouraged.


What is the math concept tested here? You need only simple arithmetic skill to solve it. The expert in the yahoo articles pointed out that even a P2 student would be able to solve it. Number does not only count in whole but in fraction, decimal too. Math concept does not tell you that you must count ribbon only in one whole.

If this is a real life case. Try if you call for a bid based on what the question say. I will not be surprised you will get 9 tapes end of the day if both parties did not clarify in the process. In examination, some student may have doubt but they were not given the chance to clarify.

Creativity. I do not see any but may be more on maturity.

Ppl who say join ribbon, if u want to buy 5 pcs of 100cm ribbon n e last piece is join w glue using 40n60cm…will u accept e reason being we ran out of full 100cm. N if can join then might as well slice along e run to half or even thirds then u get triple e quantity without compromising on length.

If ur boss ask u to organise a party n needed 200 ribbons to tie this is exactly how u need to calculate n get full 110cm length. Will u go buy loose small pcs n join n tell ur boss is creativity?. Boundaries allows thinking to be stretched. If forces u to think what u can do. This is a good question. If students think logically they should get it. Go ask ur kids how long is a school bus or how much water is in a swimming pool u will be surprise most of them do not have any sense what meter n cubic meter means though they do it all e time. Time to learn that numbers r real n in thus qns, e number’s e authentic n real.

As if anyone will ever say, I have 3 times more money than you now after you gave me $50. How much did I have originally. I think if the kids know that in a math question, they are expected to calculate how many strips can be cut from one 25m roll and therefore how many rolls they will need to cut x number of strips, then the answer is really not controversial, no? We may not like the question, and it may disturb our thrifty attitudes but it doesn’t make it a bad question.

chanus88@yahoo.com.sg:
We should send this conversation to MOE so that MOE may think twice before rejecting 9 as an answer.

Perhaps MOE may accept 9 as the answer if the child explains clearly in the working that the remainders are joined to make some ribbons of 110 cm. Without mentioning joining of ribbons in the working, the methodology will be wrong and 9 should not be accepted as the correct answer.

It is not the answer. It is how one arrives at the answer. Just saying that the question is ambiguous is not good enough.

Just saying.

Son: “Mother, can I buy the type which can be joined so that I can join them in case the length of one piece is less than 110cm?”

We should teach our next generation to be able to think in order to save monies and environment. Extra roll of 24m to use up only 0.09% is a waste (can’t remember the exact figure). How can we educate our kids to waste the resources?
