P2 Math - General Discussion

...how to improve my girl's literacy skills in understanding Pri 1 maths questions especially Section C. She scored 0 for Section C in recent test but if I read to her she can answered all questions correctly!

Sounds like that she's an audio learner - same like DD1.

What I've done with her is to read the question out loud (ok, not so loud in the classroom context)...then translate to a \"subtraction/addition/multiplication/division sentence\". Then guide her to check - which is bigger/smaller? or who has more/less? Sometimes need to get them to read and interpret mathematically.

Hi Jolyn,


Just curious abt what is the correct answer that your child's teacher had given the kids??

Btw, if \"exchange\" means 1 for 1, that shd means that there is no changes at all right??

I hate maths..Urgh!!! I will also check with my boy tonight on this question.

Thanks!!

I agree that exchange means 1 for 1. I used to exchange stamps as a child, and I definitely don't have increase or decrease in the number of stamps that I owned when I exchange !

Why can't the teacher just say give away and receive ?

It is definitely very important to make sure that kids can read very well before entering P1. But then if they encounter Maths teachers who write this kind of English, I will vomit blood !

My younger boy has problems with such exercises. What can I do to help increase his understanding?

TIA

My P2 son is very confused over the topic on "TIME". So far he is able to tell and write down the time correctly. He is also able to tell 1 hour / 30 mins before or after certain time. However, he starts to get confused when there are two clock faces with the right/left arrow in between and he has to fill in "Before / After". I get confused with the right and left arrow too. He is also confused as to how to calculate the difference in time. Any parent encounter this problem? What is the most effective way to explain this topic?

[quote=\"Jolyn\"]Dear all


I have a math question as follows:

Jenny and Jonathan collected stamps.
Jenny had 355 stamps.
She exchanged 56 stamps with Jonathan.
Jonathan exhanged 44 stamps with her.
a) How many stamps did Jenny have after giving some stamps to Jonathan?
b) How many stamps did Jenny have finally?

Appreciate if anyone could advise on the above.

Hi,

I think the question did not sound logical. Did Jenny exchange or give stamps with/to Jonathan? The story said \"exchanged\" while the question said \"gave\". So conflicting. If it was exchange, then Chiefkiasu's solution is correct.

It seems to me that the person who came out with this question lacks basic written communication skills and is incapable of presenting a problem clearly -- without causing confusion. I also find such problem with my child's school, both Math and Science. Maybe it's time MOE brush up subject teacher's communication skills ![/quote]'
aiyo yo isn't 'exchange' means i give u two and u give back two to me..... then so end up the both answer is still 355
.... the teacher who set this qn is either trying to be tricky (which I don't think so) or got language problem. :siao:

I can exchange 1 (rare) stamp with 3 (more common) stamps with my friend. Hence exchange is not necessarily 1 for 1.

I can also exchange 1 duck for 2 chicken (if a duck is more expensive than a chicken).


Based on my understanding, I believe

\"She exchanged 56 stamps with Jonathan. Jonathan exhanged 44 stamps with her.\" is meant to be \"She exchanged 56 of her stamps with Jonathan for 44 of Jonathan's stamps.\"

\"a) How many stamps did Jenny have after giving some stamps to Jonathan?\" is meant to be \"How many stamps did Jenny have after handling over the stamps to Jonathan and before she got the exchanged stamps from Jonathan?\"

While I agree with u on this, ie, 'exchange' need not be one-for-one, the use of 'exchange' in that qn is definitely NOT appropriate.

ok.. then I think it would be more sound or more apppropriate to say' jenny exhange 56 with jonathon for 44 stamps...instead of putting it in two separate sentences.. very confusing and misleading :?
