I know!


23-3=20
20/5=4

So, each child gets 4 apples

Anyone else with different answer?

Hi ksi,
Agree with teachingmum's answer. The key word here is share with. You will need to include Mrs Tan who is sharing with her 4 children. If the question says, share among or share between, only then will you divide 20 by the 4 children. Hope this helps

Actually my answer is the same as teachingmum and so is my dd's answer.

The answer key provided was 5, so I just want to see how many people would give different answers. As usual, many of the answer keys are blatantly wrong in the top schools exam paper unfortunately and I hope parents would be alerted not to mark blindly with the answer keys.

Agree. Hopefully the real answer keys are correct else our kids' ans will be marked wrong.

Hi parents,


Is it ok for P1 kids to still count using their hands, I am a bit worried as my child keeps counting using her hands, for example when I ask her what is
9 + 5, she must use her hands to count, is that normal for P1 or should I be worried?

If the child has not been exposed to any form of Maths classes before, it is quite normal for P1 children to use their fingers to count. With practice, they will stop doing that by the end of P1 or the start of P2.

Yes, I agree with mrswongtuition. Using their fingers shows they understand addition at a fundamental level, and are not just memorising symbols on a page. This builds a good foundation for critical thinking math later on.

Hi. Maths Guru, please help:


Sam wanted to buy 7 T shirts but was short of $14. He bought 6 T-shirts and was left with $9. The cost of each T-shirt is the same. What was the original amount of money does Sam have?

I have used the guess & checked method but still in vain!

Thx…

[corneyAmber]

cost of shirt = u


7u-14 = 6u + 9

u = 23

So originally Sam had (6*23)+9=7*23-14=$147

[teachingmum]

Let me see…


After buying 6 t-shirts, she had $9 left.

However, this remaining $9 was not enough for her to buy one more t-shirt. She needed another $14.

Therefore, one t-shirt cost $9 + $14 = $23

6*$23= $138

$138 + $9 = $147.
