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:

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. :?

Hi plum-cake


Good Afternoon.

The answer is correct.

Add all the shapes and you’ll get

2 squares + 2 triangles + 2 circles --------3+5+10 ----18

Therefore Square + Triangle+ Circle -----18/2 ----- 9

Best wishes

Thank you Tianzhu and QMS,


Oh , Ok I really try to find the value for each shape. Its very tricky.
I couldn solve it so how can I expect it from my dd :roll:
you mommies are really clever :salute:

No worries! So, you managed to see my post before I deleted it.

I thought my answer was the same as tianzhu's. Hence, no point repeating it.

Actually, is your girl in P1? If so, I don't think she has touched on division yet. So, instead of telling her to divide by two, maybe what you can do is to tell her this instead:

(Square + Triangle + Circle) + (Square + Triangle + Circle) = 18

So, using number bonds, which number, when added to itself, will result in 18?

Thanks again, my girl is in P2. she finished her mutiplication and division at school. really a thinking Q. :lol:

Thanks Tianzhu:)

I bought a book from popular, Process Skills in problem solving by Li Fanglan. Now both my son and I are very clear on when we use single bar and when to use two bars.
