For example is this question. It is faster to construct a table and write down the number of dots required for Figure 5, 6, 7, and so on rather than to find a formula to calculate which figure will need 108 dots to build. Do you think it is ok to construct a table instead of using a formula to calculate?

If the child is able to derive the formula, it will be great. But if cannot, constructing table will solve at least 2 out of the 3 questions. After constructing to figure 9, hopefully the formula becomes obvious by then to solve the 3rd question.

Thanks, Zeemimi. In this particular problem, my son is slow to work back the formula although he can construct the table.

I think its also weighing the pros n cons...
constructing till figure 9 can be really time consuming, but if can get the answer, good la.
but at the same time, the time spent can be used to develop the formula...
so solving math questions involve a lot of thinking process, what if I do this, what will happen...if I do that, then what may happen. While working on more questions, guide your child on how to think too.[/quote]I think sometimes it is faster to construct the table instead of working back to derive the formula. Like in this case, all answers can be obtained once we calculate the number of dots for Figure 10. But once the question asking for far away figure, then the child must come out with formula lah.

Good morning everybody. Time to work hard today. Yay!


Jia you, jia you :rahrah: :rahrah: :rahrah:

Good morning!!! 2 more weeks! :boogie:


Steady! Keep calm! Stay healthy! Run, run, run! Go for it!

Morning,


It is kind of late to ask but may I know for Science, how much of p3/p4 topics will be tested? Is it necessary to do/revise p3/p4 assessment books? I have upper primary science assessment books (topical revisions which do not cover p3/p4 topics) but not PSLE assessment books. Thanks in advance.

Did u buy the authorised PSLE booklet? This booklet should give you an idea of how much of P3/P4 topics will be tested.

I would strongly encourage the revision of lower pri topics.

Hi


I was the one who posted earlier on my experience on the usage of Algebra in PSLE Math. I dug out my email correspondence and will be reproducing it here. I have a correction to make. While I wrote directly to MOE, MOE forwarded my query to SEAB (Singapore Examinations & Assessment Board) to handle. So, the replies given were from SEAB.

Please read and judge for yourselves:

MY EMAIL TO MOE

I was informed by the school that while Algebra is accepted as a method for solving PSLE Math questions, no \"method\" marks (or marks for showing correct working), will be awarded. Full marks will be awarded only for final correct answers. This means that it is a \"do-or-die\" if you choose to use Algebra. However, if a student uses the Model Method, this can earn him method marks even if the final answer is incorrect.

I would like to seek clarification on whether the information above is accurate. And if so, the rationale behind it?

I find the preference for Model Method puzzling, all the more so because after PSLE, the secondary curriculum rarely mentions the Model Method. Instead, Algebra is taught. I know this because I have an elder son in Secondary school.

While the Model Method has its merits, I believe the examination process should give the child the choice to use other effective methods. This is more so for Algebra -- a problem-solving method which is fundamental to Mathematics and for which he or she will be using anyway in a few more months.

Both Algebra and Model Methods, therefore, could be accorded method marks. Answer sheets for standardized PSLE marking could include Algebra as well as Model solutions so as to ensure fairness in the marking process.

MOE FORWARDED MY QUESTION TO SEAB. SEAB'S REPLY:

SEAB can only provide broad guidelines as marking at the PSLE is a confidential exercise. The broad guideline to your query is “All solutions presented in a clear and systematic manner which demonstrate the candidate’s correct understanding of mathematical knowledge and application of skills will be given credit in the PSLE marking exercise.”

MY CLARIFICATION REPLY TO SEAB

I take it that since \"all solutions\" are accepted, Algebra is also accepted alongside any other solution and will be awarded method marks, not just for the final solution?

I believe answering this question will not entail reveal specific details in the marking process.

SEAB’S FINAL REPLY TO ME

We regret we are unable to reveal specific details in the marking of PSLE as it is a confidential exercise. In general, all solutions presented in a clear and systematic manner which demonstrate the candidate’s correct understanding of mathematical knowledge and application of skills will be given credit in the PSLE marking exercise.

As you can see, SEAB stopped short of saying Algebra is acceptable, preferring to give general, un-committal answers. But I personally take it that Algebra will also be awarded method marks.

Hope this clarifies, rather than confuses.

yogaqueen, thank you for sharing your email correspondences with us.


Yesterday I WhatsApp my son’s Maths teacher asking about method marks for using Algebra and she said the marking is confidential. Now I understand that it is SEAB’s guideline to keep the marking confidential.

:thankyou: for sharing.

I checked with ah boy ytd on what he was told by sch teacher.

He says:

writing let x be number of apples and y be number of oranges - no method marks awarded.

writing an equation based on the qn info, eg x + y = 100 - no method marks awarded

only the solving of equations correctly will have method marks awarded.

I wrote an email to MOE ytd afternoon, giving a specific qn and writing down in detail the equations, hoping to get a clear reply. But from your earlier correspondence with SEAB - marking scheme is confidential, it seems like I wont be getting any clear cut answer :rant:

[ngl2010]

Would writing to The Straits Times get a straight forward answer from SEAB? What is so confidential about got method marks or not? :scratchhead:
