P2 Math - General Discussion

Hello


My DS1 (8 in July) is struggling with the following question from EPH Challenging Maths P2.

DS1 will start the final term of his UK Year 3, in May . NB UK Year 3 is the same as Singaporean P2.

I am concerned that he is not able to master a question as follows. I want to ask fellow parents of P2 Children whether this is a normal P2 problem-solving question? In short should I be worried that DS1 cannot attempt it, even when I explained it to him.

The question is linked below. Please excuse the poor scanning, showing a grey shadow to the right-hand-side. Also, ignore the workings out, as I forgot to rub them out.

DS1 struggled on Part (a) for which the answer is 52 (28 + 24 seats).

Can anyone respond on 10 April, please, as we jet off for a holiday to Mexico on 11 April - for two weeks. Althhough, I most probably will log on when I get there.

This is part of the P1/P2 syllabus in understanding ORDINAL NUMBERS. In most questions, they would ask the children to identify which position is the person in from the left or from the right. In this question, it takes one more step in using the understanding of ordinal numbers to find the total in the row. This is also quite a standard question especially in queue situations, they like to know total number of people in the queue.

To me, this is practical math, when you are holidaying in Mexico if you are taking him to any children's playland where queueing in a must, try to play a practical game with him to ask him if he is standing in position X and you in position Y, how many people are in the queue if he does not need to count one by one....perhaps he would see the connection and be able to understand this better. Good luck

Agreed with ksi that you can probably explain the concept when you are out with your children, they might understand better.

My girl who is in P1 is already attempting such questions and I also see several similar questions in her assessments...Hence, it is essential for kids at P1 to start grasping such concepts..

Yes, school started. I can understand Part-whole model and comparison models.... he do not quite get it for some reason.... I ran out of ideas on how to explain all these.....

Hi Idono,
Have the school started teaching modelling?
I had trouble making my child understand models when I tried to teach him in P1. But it took only a few lessons from his Math teacher and now he is better at modelling than I am :oops: .
To start, P1/2 modelling is essentially 2 typees; Part-Whole model and Comparison model (I think there will be 'multiplication modelling and division modelling at a later stage although I am not well-versed in it). The child must first know how to differentiate when to use which. I did not know that when I was frantically trying to teach my child how to draw models based on the problem sum. It was my child who first introduced these 2 'new terms' to me. :oops:

my friend asked me this P2 Math question, can somebody help? the answer is 73, but how to get 73?

Hi KSI

I have tried with this, however, believe it or not DS1 is more interested in swimming here.

I will try the question again when we get back to England, next week.

We are all sunburnt and dying to get back home. Mexico is not all it is cracked up to be. :x The fellow tourists, especially from Canada, are wonderful companions

PS, to Anna Ng, this is a difficult question and I cannot get t5he answer too.

Hi, Can you post a clearer image....I cannot see the numbers...blur and too small.

If he likes swimming perhaps you can use swimming to teach ordinal numbers, it will appeal to him better.

I also don’t know how to derive the answer…

Pls help me


Jovi had 2 strings, string A and string B.Initially, string A was thrice the length of string B. Jovi then cut 9.1m from string A and 140 cm from string B. The length of string B became 1.5 times of string A. What was the length of string A at first? Express your answer in centimeters.
