Thks Tianzhu,

the article is abt the stress that kids in Singapore are facing now, they then give a few examples of the Math question that our P2 and P4 are getting.
after reading the article, i feel for the children, as quoted by one of the parent: \"the kid is learning how to cycle and juggle at the same time\"
i wish something can be done to lessen their work load. Children shld have a beautiful memories of childhood and not buried in books all day long.

if not for the help i got here, i doubt i ever solved those question

Good Morning chloecube & Tianzhu :grphug:
Totally agree with chloecube; I have learnt and am still learning about Maths. Am so thankful that I can tips from this P4 Maths thread :salute: :salute:

I think these parents are stressed coz they r not happy with a band-1 or A grade...they wanna A* or perfect100. I believe there are usually only a couple of such difficult questions unless u r from a premium school. Even if u don't get them right and get the rest correct, u should still get band-1.

Hi

In answering these questions, it may useful to get your child to read the chapter on Factors in the school textbook.

Q1) The answer is 9 (1,3,9).

Q2) The number 50 does not have 6 as a common factor.
The sum of 42, 72, 84 and 96 is 294

Patrick had thrice as many marbles as Joe.

Patrick gave away 15 marbles and Joe gave away 3 marbles.
Then they had an unequal number of marbles.
How many marbles did Patrick have at first?

Hi

additional information for Q1. All numbers have even number of factors except square numbers. So, if we are looking for odd number of factors, we can narrow the search to square numbers only ie 1x1, 3x3, 5x5,7x7 etc.

cheers.

Hi

If unequal is replaced by equal, then the answer is Patrick had 18 marbles at first.
