btw, China qn 8 .. just discovered the answer (not by me), works by cycling the numbers incrementally..

1 + 2 + 6 + 1 = 10
8 + 1 + 2 + 8 + 1 = 20
5 + 1 + 8 + 5 + 1 + 8 = 28
7 + 5 + 4 + 7 + 5 + 4 + 7 = x ( x= 39 )
5 + 7 + y + 5 + 7 + y + 5 + 7 = 87 ( y = 25.5 )

my ans so far:
1. 21 x 42 = 882
2. (c) 60 - seems a lot easier than i tot.. wonder why it's in the list. any catch ?
3. 65 - not sure any catch
4. 55
5. (j) 14
6. A=6, B=1, C=2 (see swiftdad post)
7. dunno - https://www.kiasuparents.com/kiasu/forum/viewtopic.php?f=1&t=88956
8. not yet solve
9. 87
10. not yet solve

1.5 hours to go…and can relax for the weekend … the week’s been too long!

i see.. unfortunately, since no answer to learn from !


agree - maths is only a tool for problem solving. if we focus only on using the 'hammer', then we may end up treating everything like 'nails'.

Coke Chan:

thanks, swiftdad - your solution breakdown is good!

I haven't actually got down to try all the questions myself or with DD - just trying to see whether there are similar questions out there on the Internet. The qn 7 SG maths problem you mentioned has been tackled by some of the parents in this forum ( check out https://www.kiasuparents.com/kiasu/forum/viewtopic.php?f=1&t=88956. But i think there is no conclusion answer yet.

I actually prefer the the open-ended Asian questions than the Us/uk questions, as they challenge some out-of-box thinking for the child in a way that it should not always require a formula to solve a maths problem. These questions encourages some observation, deducing and figuring out of the problem pattern before deciding on a solution. A formula is only a technique to achieve the solution.

good info. thanks for the timely link!

Okay, lazy sat afternoon, so tried the 10 questions in the link with my DD twins at P3. Combined, we did 6 out of 10. The ones we could not solve were (qn 4) HK P1, (qn 7) the famous SG problem, (qn China P1 and (qn 10) Preschool (?).


Although my P3s solved (qn 6) China P1, I find it interesting as it requires some serious deduction:
AB + AB = BCC - What numbers do A, B, C represent ?

- First of all, child needs to assume A, B, C are single digits.
- Then, child must deduce the sum of 2 two-digit numbers < 200, suggesting that B = 1 or B = 0.
- If B is 0, then the answer is C = 0 and A = 0 (unlikely).
- So, B should be 1, which implies C = 2, which implies AB + AB = 122, which implies AB = 61 and thus A=6.
There's quite some deductive skill to be expected from China P1 students!

I have teacher friends in the UK. They have also thought that the Western curriculum for early maths tends to be more direct and 'verbiage'-based (wordy), while the Asian curriculum tends to train cognitive skills e.g. pattern matching, open-ended thinking at early stages and thus, it reflects the difference in the flavour and style of questions in that list of primary school maths questions posted.


In fact, UK is now trying to embed the Asian curriculum/textbooks, largely from China and Singapore, into their maths curriculum. So a reverse of influence, from the UK's influence of GCE on Singapore and now, Singapore 'kiasu' education back to them - irony!

i feel the USA and UK test questions should be doable by kids.. but the Hong Kong and China questions are a bit too tough for young children, supposedly for P1 admission :yikes:

thanks too, am a new member and this site is a trove of info for a blur parent like me.

This site has been my constant companion and the site to go to for advice. Addicted ever since.

used to think a lot on purpose of life, but now the life journey at mid-40s feels tired and stressed… the purpose left at this point is to bring up the kids well into useful people in life… and by then i should be 60+, think i can rest and slowly say bye bye…

timely, maybe, but uber and grab can be more ex than taxi, their price formula not transparent…

That’s correct, I work in the telco industry and we outsource the Internet home camera installation to local suppliers. Homeowners are advised to change their password for the Internet cameras but many of them keep as default password or easy to guess passwords.
