# Is PSLE Math really that difficult?

The recent 2021 PSLE Math paper has done it again! Every year, students and parents take to the internet to consult one another on how to solve a particular math question. This year is no exception.

Question involved: (source: Mothership and CNA)

Question from my whatspp:

*Apparently, there’s different versions of the question. A reader alerted us.

I admit. I tried to used algebra to solve it. It didn’t work.

I wanted to text the person who shared the question with me that there must be some other information or that the question is incomplete. Otherwise, how can i not solve it?

My second attempt at the question taught me something. Sometimes, it the user that complicates things. The Singapore Math Model uses Bar Modeling as a pictorial method to solve word problems.

Solution based on my whatsapp message:

Please take note that diagram is not drawn to the correct scale. (It doesn’t need to)

And that both Helen and Ivan have the same number of coins.

From the above bar model, we can deduce that it does not matter how many coins do each Helen or Ivan has nor does the question ask the student to solve for the total number of coins.

What we should take note of is that as Ivan has 40 more 20 cent coins than Helen, it would mean that Helen would have 40 more 50 cent coins than Ivan. (Only 2 type of coins involved here, 20 cent and 50 cent)

From here, we know that having more 50 cent coins would mean Helen has more money and by \$12 (Difference of 50 cent and 20 cent X Difference of 40 coins)

Since Helen has more 50 cent coins, Ivan’s coins would weight lesser than Helen’s. And what’s the difference? (2.7 g X Difference of 40 coins) = 108g difference.

Therefore, mass of Ivan’s coins = 1.134kg – 108g = 1.026kg.

My math tutor used to tell me that it’s alright when I cannot mange to solve certain questions in the paper. I was quite puzzled by what he said. Now, I seem to realize what he meant. He was saying that as his assumption was that I was able to complete the math papers with above 75% grades on a consistent basis. And that if there were any questions that I could not solve, it still would not amount to my grade being less than A1.

However, it has always been my goal to get 100% for my math papers. In reality, when you aim for 100, you may fall short a little (careless mistakes, silly errors, etc). But chances are that you would still get the highest possible grade of A1 or AL1.

So I ask myself: “What would my overall math grade be, if I failed to answer Helen’s and Ivan’s coins question”?

How can you prepare your child for the GEP Identification Exercise?

Is a gifted child a product of nature or nurture? Since time immemorial, this has been a highly controversial subject. Evidence from many recent source points to the superior character of most of the homes or families as a strong contributing factor to the high standing of these boys and girls whose I.Qs are 130 or higher. According to the University of Chicago Press Journals, other than genetics, nurture is an important consideration and there has been a consideration of methods of training gifted children.

To help parents better prepare for the challenges of the GEP Prep test, we provide a 16 hours of intensive preparation (6 lessons of 3 hours each) to tackle the commonly tested components of the GEP Screening Exercise. All lessons are conducted online in small groups. Contact us today for more details!
