P2 Math - General Discussion

[UmmuMuadz]

Hi,


I was going through DS1’s Maths Textbook yesterday.. He’s in Primary 1.

Under the topic addition / subtraction within 20, the method is follows:

12 + 3 = ___

First, break the 12 into 10 + 2

Second, take 2 + 3 = 5

Lastly, the to get the answer, you take 10 + 5 = 15

This is the method he was taught in school. This is the first time I come across such method. :shock:

When asked whether he understands this method, he said no. Instead, he is using the old school method of putting 12 (in the head) and calculate using the 3 fingers to add on.

I would like to ask if the textbook method better in terms of making the child understand the concept as compared to the old school method?? :?

Thx

This new method uses the strength of number bond for 10s to help the children calculate faster.


Using fingers for calculation has its limitations so it is not encouraged as numbers get bigger.

Abacus method also uses number bonds of 5 and 10 to calculate big numbers.

Hi there UmmuMuadz... same here, my DD2 is in P1 as well.

If you have noticed... the FAN-Math books that you got from me also
encourages the method used above. It so calls encourages children
to find it easier to calculate without the use of fingers, stick or circle
drawings, or even the number line... it moves towards the method of
speed maths which is more of a mental calculation.

During the early stages of Primary education, it is more on these number
bonds' skills, which if nurtured; can be automatic for them and assist them
to solve math workings much faster.

UmmuMuadz:

While there is nothing wrong in using the old school safe method of
counting, it is still nevertheless essential to learn it... cos i dunno lah
yah... it comes out in the children's assessment/class test and exams
(at least for both of mine).

UmmuMuadz:

I would like to ask if the textbook method better in terms of making the child understand the concept as compared to the old school method?? :?

If the child eventually grasps the concepts, understands how it simplifies
their counting process and in the end, able to apply this method in his or
her assignments, then the answer would be a BIG yes to it being a better
method as compared to the traditional ones..

PS : If you've noticed, the textbook method introduces the ability to *so-
call calculate faster when one number is rounded off to ten. As the
numbers get bigger later on... i assure you they will (become bigger!)...
children will have to round off one number in math questions like the one
above, to the nearest ten.. ie. 22+5 is broken up to 20 and 2+3..

*Why so call? Cos while it challenges my DD2 to work with even bigger
numbers, my DD1 finds it a hassle and like your son, she used to say
dunno... dun understand... and also dowan to understand.. :politebleah:

:faint:

So, UmmuMuadz... hope this helps.

Hi ksi and buds,


Thanks for the clarification

I guess when I saw it for the first time last night, I felt that its quite confusing, well at least to the \"old skool\" brain of mine

It took me longer to solve the problem using the textbook method but my son could do it quite quickly. :lol:

In fact, he was also showing me how to solve 22+5 using the textbook method. I bet he can also solve 30, 40 using the same method. Come to think of it, he did understand what the teacher taught him. Thats a relief.

Thanks again for the clarification. :celebrate:

Thanks for the clarification

You're welcome and it's a pleasure really.. :hugs:

Yeah! I know watcha mean girl! :roll: Me too! :lol:
Old school brain takes time to receive and adapt to new things. :politebleah:

UmmuMuadz:

Yep, initially i saw it as an extra troublesome step.. heheh..
But children grasp it much easily and have the ability to apply what
they have learnt much faster than we credit them for huh?

UmmuMuadz:

In fact, he was also showing me how to solve 22+5 using the textbook method. I bet he can also solve 30, 40 using the same method. Come to think of it, he did understand what the teacher taught him. Thats a relief.

Yeah! I bet so too! :celebrate:

Hi,

These qns are under the "Addition and Subtraction Within 20" topic.
Qns 1: ___ +8-5= 10
Qns 2: ____-7+4=10

Any advise on how should i teach my ds? Thks!

A friend of mine told me to get Shaping Math for son in P5 to practice…also got Li Fang Lan (set of 6 books) for daughter (going to P1) recently.


Fabian Ng is also good for problem-solving, but not avail for P1. Could only find Simon Eio for P1. Any other Maths assessment book to get for P1 ?? Thanks.

janet,

is Simon Eio book available in popular? If yes,which publisher is he with?

[janet88]

Hi Pokemon,


Step-by-Step Maths Problem-solving using models by Simon Eio.
Publisher is EPH…I bought it from Popular. Li FangLan also has a model approach assessment book.

:? Hii all I need help !


My older boy just went to P1 this year. Initially he is good in his maths and English and always has an interest in reading.

I only send him for Maths tuition every Sunday. He has been going to the same teacher since K2 and is the only one in class.

He has always got good feedback from the teacher and I often buy him many assesstment books to practise. The only time he is told to study harder is when he is having his SA1 and the maths paper is today.


Since he has started Pq, he has become more vocal in talking ,most of the time spouts nonsense. Sometimes he can be a real good boy.
He just doesnt want to listen to me when I teach him Maths. I have tried talking to him many times with a soft approach. but he makes funny faces or reacts in a manner that shows me that he is not listening.

I have spoken to his teacher and she says that he makes silly mistakes at times. Even the tuition teacher told me last week, that my son used to be above the rest but now he shows an attitute of laziness and doesnt want to listen.Its not that he doesnt know his maths, he puposely doesnt want to think and wants the answer to be given to him.


I am very worried with his attitude. There is a boy who is in the same class as him and they are friends from the same MMI. but they only play during recess and sit separately in class during lessons.

After trying the soft approach, I had to resort to showing him the cane ( just to scare him).There are times that I have given him a soft whack on the bum... but still he isnt bothered.

I have never controlled him in any way, and he buys whatever he wants ,,, I dont spoil him too much anyway.

Today morning ,I went through his maths with him... he just didnt want to pay attention and they are simple things like

2 + 2+ 2 + 2=____ X 2

or just simple length ..i am very worried and dont know what to do. I am thinking of stopping his Maths tuition in June and lettng him rest..but I dont know if I am doing the right thing ...
