P2 Math - General Discussion

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.

Hi!


Usually 2 or more model bars are drawn if the questions involved comparison such as more than or less than for pri 1/2 maths questions.

If it's a one step question, it will usually include info for more than or less than or question ask for how many more/less, you will need a 2 model bars.
If it's one step question and asking for altogether, it's one bar.

If it's a two -step questions, usually it's 2 bars.because they will usually provide info for one subject then find the second one using addition or subtraction. then finally ask for altogether.

hope it helps

by the way your child should have completed the first term. has he/she clear the doubts on model drawing?

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!

Wow, the triangle / circle / square question is too tough for normal students! haha

HI Plum-cake,

Guess what, I finally learnt how to answer the question on calculating number of 2 and 4 legged birds/animals last night :oops: while hubby taught daughter last night. The Math assessment book used is Li Fanglan's heuristic and model approach.
