Yesterday Miss Loi was at Popular Bookstore with a friend who was shopping for PSLE assessment books for her son who is currently in Primary Six.
Having stopped tutoring Primary School/PSLE Math for a long time, Miss Loi was curious to know their standards these days and so she picked up a few of these assessment books and started flipping through the pages – at the same time wondering with a smirk how many nanoseconds she would take to solve each question.
That hypothesis was quickly thrown out of the window when she saw stuffs like these:
(click to zoom-in and view the questions, and apologies for the somewhat blur images as Miss Loi stupidly forgot to use the ‘flower’ mode of her N73)
Wow. Mensuration problems usually taught in Secondary One/Two E-Maths. These should take Miss Loi more than a few seconds each *massages battered ego*
Yet more browsing brought her to this:
What the … ?! Isn’t this almost like the Lazy Bugger Algebra Question Miss Loi posted here on April’s Fool Day? You mean Miss Loi actually posted a PSLE question disguised as an E-Maths problem???! She even mentioned that it had many of her O-Level students stumped!
Thrusting this aside, she opened another PSLE assessment book and saw this:
Suspecting that she had seen something similar before, she quickly took out her O-Level 10-Year Series and sure enough … :
Desperate and confused, she was now frantically flipping the pages like a mad woman. Her friend had already begun to move slowly away from her. And the salesgirl at the counter was also frantically flipping the pages of the phone directory for IMH‘s number.
In all these years, had Miss Loi really been teaching O-Level or PSLE Maths?! She got the shock of her academic life when she saw this:
This is an A-Level question from the Series (Methods of Differences) syllabus! Compare that to something similar take off a maths tutorial from a top Junior College in Singapore:
Notice that the JC tutorial question at least provided some hint/clue at the front while the PSLE one simply demands you, in no uncertain terms, to “Find the sum”!
Fast-forward to today.
To reassure herself that yesterday wasn’t some sick nightmare, she posed the last PSLE question to some of her A-Level students.
The result? One of them couldn’t solve it while another needed to use her super-duper graphical calculator to get the answer. Oh dear, Miss Loi’s ominous prophecy looks set to be fulfilled afterall.

Miss Loi, I am ashamed to let you know what passes for PSLE math test questions in the USA, though I'll try to find a copy for your amusement and my embarrassment. They are probably equivalent in difficulty to the math questions that each Singaporean needs to answer in order to leave his or her mother's birth canal.

Lol thank goodness we don't have BCLE (Birth Canal Leaving Examination) - yet!
Wonder what will happen if the baby fails!

Oh my goodness!!!! Miss Loi, are THESE really PSLE questions? They learn Pi in primary school?
Somebody get me the digital couch, I need to sit down.

Coming soon to a kindergarten near you:
English class: A for Apple, B for Boy, C for ...
Maths class: α for Alpha, β for Beta, γ for Gamma ... π for 22/7 ...

1/6+1/12+1/20+1/30
Primary Wiz kids would see the pattern
by numerator 6,(6+6=12),(12+8=20),(20+10=30), (30+12=42),(56),(72) Last term(9900)
But still unable to get a clue

Aldwin,
On behalf of the Primary Wiz kids, Miss Loi would like to thank you for trying.
FYI, a peek at the solution for the question in the book revealed that Methods of Differences were indeed used to solve it, just that they didn't name it as such!

My sister is going to answer PSLE in 2008 in Myanmar. Her email is crystalsandi@gmail.com. I want you to sent some Maths paper to her email.
I hope you accept my request.

Thanks for dropping by Jessica. Unfortunately only O-Level (and not PSLE) Maths papers available here.
P.S. Interesting that Myanmar also have their own version of PSLE!

These questions can be solved by heuristics approach... The model approach is normally used to solve stimultaneous ad fraction questions.

Sunnie: Neighbour?!
Hello miy0k0. Yes PSLE is coming soon but you shouldn't have anything to fear if you've been practising your maths regularly.
Unfortunately, Miss Loi's questions are all dealing with Sec School Maths so it's best if you can ask your teacher/tutor or lookup PSLE assessment books (obviously not those mentioned above if you're not confident of your math foundation!) for relevant/important maths questions.
Good luck for your PSLE and Miss Loi will see you in Sec One soon! 😀

All these questions frequently appear in maths olympiad for primary school. Nowadays very common
I am pretty surprised that you didnt teach primary 6. I guess you are specialised in your own way.

My son just sat for his PSLE maths paper. Conclusion ; he could do it, but I can't !
The fact is, we are having the next generation who are better than us, that is the intension of Singapore MOE.
Good luck !

The 2009 paper has a question that I couldn't do without resorting to algebra! Well yes they're taught algebra, but not simultaneous equations nor dealing with more than one variable!
I wonder what the marking scheme would look like for this question:
Jim bought some chocolates and gave half of it to Ken. Ken bought some sweets and gave half of it to Jim. Jim ate 12 sweets and Ken ate 18 chocolates. The ratio of Jim’s sweets to chocolates became 1:7 and the ratio of Ken’s sweets to chocolates became 1:4. How many sweets did Ken buy?
And while we are at it, can Miss Loi attempt this Primary School Style?

ong: Used to teach PSLE maths many, many years ago but these days Miss Loi & PSLE maths have a bit of a 河水不犯井水 relationship (i.e. River water don't mess with water from the well ... you get the idea). 😛
wilson: Simply being able to do a couple of naughty PSLE maths 2009 questions means that they will be better than us meh? The road is still loooong ....
mathslover: There are already TONS of full step-by-step solutions (that carefully avoided algebra/simultaneous equations like a plague) to that naughty Jim & Ken barter exchange question on the net if you google it.
So don't think it's necessary for Miss Loi to 插一脚 into PSLE affairs here 😉
