If dd learned this during Pri level, she won't suffer this much now.. but I think she may have issues solving this type of problems due to carelessness.

It’s super inefficient on these sort of questions. Solving questions this way could result in not having enough time to check the paper or even complete the paper.

However in secondary school, yes u are expected to learn and use algebra fluently. There will be a lot of questions that models cannot solve. Their minds are more developed to handle complicated high order questions.

Have your child practice more, keep track on what was the mistake, systematic or transfer or calculation error? Practice practice practice

I am not saying a P6 can form these algebra equations to solve the question as I am only showing the steps to that someone who was unaware and asked parents to show her the steps how it can be done.[/quote]Oh haha 😆

Thank you for sharing this!

Thank you all…


I need try to look at the Math see if I could still follow.

Using the model method, one critical insight is that since both Helen and Ivan have the same number of coins, Helen would have another 40 50 cent coins.

Without this insight, I would think that many P6 pupils would be staring blankly at their drawn models and cry…

And before looking at the answ, I thought the qn was incomplete lol..

That’s true. Not easy.
You feel like you need to know the total number of coins Helen and Ivan have as well as the weight of a 20 cent coin. But this information is not required. That’s why some children will get panicky and cry.

Those parents whose kids have yet to take psle papers, pls remind them, if can’t do, pls move on and do not stare at the paper blankly.

To me, I will use algebra instead of model method, as it is more easy for me to use algebra.....provided the answer is correct, no need to insist whether algebra or model method is used.

This make me recalled the time I had an argument with my Japanese teacher because she insisted that I had to answer the test paper in \"Romaji\" to show that I knew how to use the \"Romaji\" but I could directly answer the test paper in \"Hiragana and Katakana\".

Wow, thank goodness my teachers (not even the Business Japanese teacher!) did not make me write rōmaji! - I wouldn't know where to parse... But she was shinsetsu not to have you write kanji (we were not to use hiragana if there's a commonly used kanji)

Helen/Ivan. Simplified accepted answer for a 2marks-each-part qn. No need algebra or models also can… math Olympiad type of thinking


a) 104-64= 40 (coins diff)
50c - 20c= 30c (value diff)
40 * 30c = $12 more

b) 40 * 2.7g = 108g
1.134 - 0.108= 1.026kg

I also tried algebra at first glance cos like u all, I’m old 😆 Kids not just have to learn to solve problems but also to know best means to do it. More Options good. Algebra skills of course must let them be aware too but if they are not ready, can still acquire later

Just curious..is there answer for Helen & Ivan qn.

Pls ignore..I go Google..

I just watched..you need some exposure to this kind of qns In order to answer? And where do we usually see this type of qn? I agree with model mtd for this type of qn..very clear.

Hi MKS, to answer your qn, the kids are taught how to solve this type of heuristic qn beginning of P5.

Of course my son’s class forgot. After the PSLE qn made the news and everyone was talking about it, P5 Math teacher went through it during HBL Zoom again to refresh their memory.

Personally, for a child to be able to recall & implement under exam conditions is not easy. The P5 boys could all solve part (a) on their own using their own methods, but only after thinking very long, definitely longer than under exam conditions.
