Hi SAHM_TAN


I am struggling to get him to do somethinglike 2+ [] = 5. So I use fruit, marbles or toys. Just need to know what other parents do to teach subtraction.

HI,

Just to confirm, does he have any problem when the question is 5 - 2 = ?

If not then I think the confusion is because of the placement of the ? Then, what about introducing the Part-Part-Whole concept?

You know like the linked circles used to depict number bonds or even simple model.

Intro the concept that 2 is a part and so is the missing number. Then with 5 as the whole... this concept helps DD to handle bigger numbers up to 100..

optimist forum, the EPH book is it the one by Andrew Er? Frankly that book is fairly difficult - but its good as it shows me the standards out there.


My girl is in K2 and she was also having problems doing the sums you mentioned. So I am using models now to teach.

So in 4 + _ = 6

I will make her draw a model diagram. Not easy to describe using words, but let me try.

There are 2 small blocks sitting on top of 1 big block.

So the big block is 6, and one of the small blocks is 2. When she had that diagram, she could immediately tell me the other small block is 4. And I explained that the stand alone number beside the = sign is always the "whole" so should be written in the big block.

It is essentially using the whole-part concept some mummies mentioned above.

I really agree about the fact that we should lay the foundation for the language first. The maths concepts may be easy, but the way it is asked makes it baffling for P1 kids.


For example, my girl gets confused by questions such as is - What 2 numbers before 4? It may seem so simple, and I was shocked that she didn’t know. So I started by revising the concept of before and after. And then teaching her how to count the 2 numbers.

I cut out flash cards of the numbers and played a game, and get her to "test" me and I will purposely answer wrongly. So if she can correctly phrase the test questions and then correct my wrong answer, at least I know she truly understands the concept.

I figured that with 3 months to go before P1, I need to drill in the basics of the language understanding, rather than push her to do difficult questions which she may not have the foundation for.

Based on your inputs… i think i have stressed my lil one too much… oops…


she is doing those lengthy problems sums… and she sometimes get it right and sometimes wrong…

her only issue is she is very very careless… she can do the sums properly and in order… but the final answer she can write the wrong digit faints instead of 32 she can write 23… haiz…

I also agree that good understanding of the english language is very important.

btw… anyone started on multiplication??

[michyms]

r tiff, I also tried to push my girl to do problem sums, but like yours, its a hit and miss affair. My conclusion is that she doesn’t understand it all the time, so she’s guessing whether she is supposed to be using addition or subtraction.


So now I figured I better get her foundation and understanding straightened out now, then when she is faced with the problem sums next year, it will be a breeze.

I do plan to intro some multiplication to her before P1. And definitely get her to memorise some timestables.

I don't think you need to introduce multiplication so early - my daughter only started it after the September holidays and more in terms of the concept (e.g. three groups of three = 9, 5 groups of 2 = 10) than learning timetables.

I feel it's more important to make them comfortable with numbers in general and maybe basic addition & subtraction. They take it very slowly for P1 maths.

Nsm1, thanks for the advice. Do they go slowly in primary one? Or is the speed very fast?

Dear SAHM, laughingcat, RRMummy and michyms


Thanks for the advice. I am having withdrawal symptoms today as I have not been on Kiasu; I am at a conference.

DS2 can do questions like 5-2 = 3, etc...

As michyms said, i may need to teach him that 2 + [] = 5, and that 2 is a part of 5. I have tried to drill him by stating \"use takeaway\", when looking for more, less or difference. It is early days but looks like working. Tried number bonds too. I think the michyms part concept may work.

I will let you know in 24 hrs when I get back home (which will be Singapore midnight, so 2 days will suffice.........lol).

PS, michyms, the boo I mentioned is Primary 1 Step-by-Step Maths (New Syllabus). It is a great reference and question book. https://www.popular.com.sg/jsp/product/product_detail.jsp?vpd001=67955&vsc=false

I was worried my DD1 cannot cope with primary school transition. so I thought I should give her a headstart.. esp in maths since I find she is weak in it.. So I have been going through the P1 assessments books for quite a while, as I dont know if I will have time to do the assessments once she is in P1.. as I heard there may be homework almost everyday.. haizz...


As for multiplication... I started with 1 timestable on Jan, 2x on Feb and so on.. so she has learnt her 9x for this mth.

During mid year she learnt the 3 groups of 4 concept in her enrichment class, and I feel she was able to understand the whole concept better.

I believe good foundation is very impt... too :))

Hi! I believe you have started and lay a very good foundation for your DD! :celebrate:

Do not worry too much about her being unable to cope in the P1 transition as I believe most children will get into the gear pretty fast!

Ok, wondering have you read the following? This is the MOE guidelines on Primary School Maths syllabus and it does spell out what are the topics being taught
