How heavy are eight $1 Singapore coins? Six grams, 60g, 600g or 6kg?

That question in the Primary School Leaving Examination (PSLE) mathematics paper on Friday (Oct 2) has upset a number of people, including parents.

Here’s the views from the Founder of this website.

The Math PSLE question is FAIR. The outcry over the fairness of ‘What is the likely weight of 8 $1 coins?’ has only 1 yardstick – is it in the MOE Math Curriculum? And IT IS. An assessment is fair if students are tested on what had been taught. According to MOE Math Syllabus http://www.moe.gov.sg/…/scienc…/files/maths-primary-2013.pdf, it is apparent that this is within the Primary 2 Math curriculum (pg 40), under Length, Mass and Volume.
‘Students should have opportunities to:
(a) recognise that the term ‘weight’ is commonly used to mean mass in everyday situations;
(b) compare masses of objects using balance scales;
(c) use everyday examples to develop a sense of
– how long 1 m/ 1 cm is, e.g. using a metre ruler, width of a fingernail;
– how heavy 1 kg/ 1 g is, e.g. using a packet of sugar/ flour/ rice, a pin, a piece of paper
– how much 1 litre of liquid is, e.g. using a bottle of mineral water/ cooking oil, and 1-litre containers in different shapes.’
The only question now is whether the students are exposed to these adequately. It also shows the importance of referring to MOE syllabi (found on MOE website) when preparing P6 students for PSLE.

If the students have been taught on logic questions like such, it might not be an unfair question. At Primary 6, it is necessary that kids have already developed such logical thinking skills.

By sheer elimination, the pupils should be able to arrive at the answer.

Option A, 6g, is too light while option D, 6kg, is simply too heavy.
That leaves option B and C.
It cannot be option C because it would mean that eight coins weigh slightly more than half a kilogram.
That’s about the same weight as 600ml of water.
Have you ever felt like you carried 600ml of water in your wallet?
