Hi plum-cake,

Met daughter's teacher yesterday when we went to pick her.
Her FT very concerned about number bonds which my daughter seems to be weak in. I feel rather stretched at both ends now - P1 and P5.

Hi Janet,
I know how you feel about being stretched....my DDs are in P6 & P2 and preparing both of them for CA1 was a real challenge. Sometimes, I tend to give priority to DD1 as she's sitting for her PSLE this year & her work is much harder now. Feel guity sometimes as DD2 tends to be left to fend for herself.

As for number bonds, I agree with plum-cake.....keep practising addition & subtraction with your DD

Your gals are 4 years apart too? I will face this prob next year when older one is in P6, sitting for PSLE and younger one going to have SA2.
Will work on her foundation next wk. Thanks ladies.

Hi,


My son is in P2 this year. Until now, he still has difficulty figuring out when to use a single model and when to use a double model. Each time I ask him for rationale, I get a different explanation. This makes me just as confused as he is. I went to http://www.mathplayground.com/ but found that all the models there are double models. Is there any site that a P2 child go have hands-on like mathsplayground that can stengthen his and my understanding on situations for single and situations for double models? Or could anyone please advise me on the rule so I can be less blur and would be able to better help my son?

Thanks much!

Hi plum-cake,

Your DD did well overall. :rahrah: Carelessness seems to be a common problem with kids. With practice, kids can usually overcome this. DD1 was like that when she was in P1/P2...either transfer the wrong answer or careless calculations. After lots of practice and reinforcement, she managed to change her habit and is not making too many careless mistakes these days. I'm sure your DD will overcome her carelessless. :lol:

Thank you Tinkerbelle
hopefully...

I thought am having a lil break but she is having her piano( practical) exam on 22nd...

Hi plum-cake,
All the best to your DD with her piano pract exams. :ugogirl:
What grade is she sitting for? DD2 started late so will only have her Grade 1 pract exam in Sept. :lol:

Hi onlyling,
Sorry....what do you mean by single model and double model? Do you mean drawing 1 or 2 models to solve parts (a) and (b) of a question? Or do you mean when to draw 1 bar of model eg. part/part/whole question and when to draw 2 bars in one model as in a comparison model?

Hi plum-cake,
All the best to your DD with her piano pract exams. :ugogirl:

Thank you.She started when she was 3. group lessons. She took her Gr 1 when she was in k2. we didn do any exams last year. I wanted her to adjust with the school timings ...so now she is taking gr 2. I dont like to skip the grades. cos I've noticed teachers teach only the exam pieces. I want her to learn beyond that. some songs may be. thats why we are going a bit slow. one exam per year....

Impressive...your DD started piano lessons at 3. DDs also taking it so & easy. Furthermore, their piano teacher doesn't like to skip grades either. She believes in builing a stronger foundation for the gals. As for my DDs, well, it's all done in the name of fun.

Good luck. :xedfingers:

Hi Tinkerbelle,


Hmmm…I was referring to, when to draw 1 bar, part part whole and when to draw two bars to compare. Tks, now I know the right term to use, bars is it?

However, I am also not sure about the first one you mentioned - when to draw two sets of models. If there is only one question, ie no part a) and b) indicated but the questions needs some steps in order to get to the answer, can we draw more than one set of models? I have seen my son drawn three bars for comparison in questions that I thought may be clearer if two sets of models were drawn instead. Should any models come with three bars?

Thanks much!

Hi

Good Evening

Model Drawing helps students to solve Maths questions in a pictorial way.It enables a student to “see” Maths.

Some students start as early as primary one learning basic configurations like “part whole model” and “comparison model”. These form the foundation for MD in later years in primary school
.
A child should be free to express himself/herself. Using the fundamentals of MD, he/she should be encouraged to explore different forms of MD to solve problems.

Whether one bar or rectangular block, two blocks or three blocks or even drawing the MD in vertical form or a combination of vertical and horizontal form is perfectly alright so long as it helps one to reach the solution efficiently. In upper primary, one may also need to draw circles or other shapes to differentiate ratios or fractions of different measures or kind. There’s always more than one way to solve a problem pictorially.

It’s important to build a solid foundation in the early years, after that how a MD look is limited by the imagination and creativity of a student.

Best wishes

Need your help, Please.


This Question is from Fan-Math New Mathematics - Topic by Topic - P2 Page 43, Question 27. (Thinking Maths).

Each shape represents a number.

Square + Triangle = 3
Square + Circle = 5
Triangle + Circle = 10

Square + Triangle+ Circle = ?

ans given in the book
3+5+10=18
18 / 2 = 9

I don't under stand the ans. must be wrong. :?
