Let me know if you have answer

2 stars + 1 circle = 180

1 star + 1 star + 1 circle = 180

1 star + 90 = 180

1 star = 90

1 star + 1 rectangle = 160

1 rectangle = 160 - 1 star = 160 - 90 = 70 (Ans)

Has anyone got a Internet link to a site that can take DC through the use of models in maths. This is for P2 Maths.


So far, I have downloaded a P2 worksheet from Cybersource. DS1 will attempt this in his afterschool club tomorrow.

However, to put into context we had attempted the following question from EPH P2 Challenging Maths,a nd it was best attempted using a model:

A, B and C are 3 numbers. A is more than B. C is less than B. How much more or less than A is C?

In summary, I am looking for a site that can give easy guidance on understanding and creating heuristic models? Can anyone recommend a site?

Can't really help you by providing the web link... but I remember reading many websites on model drawings in the forum... do you want to do a search?

I have not got the book to hand, but it is the examples in Chapter 2, Examples 1 or 2.


It is the new edition of the book, I bought it a few months ago.

PS, what do you think of the book. I think it is great.

okay, mine printed in 2006. I couldn't find the same q. yes, not bad. the book formatted in different way. there are sub topics like terms to note, examples, take note then the questions. And the Qs are arranged sec A type Qs and sec B type Qs. last one is creative thinking. but I have no time to do that. already planned, and sticking to my timetable.....

Hello


My DS1 (8 in July) is struggling with the following question from EPH Challenging Maths P2.

DS1 will start the final term of his UK Year 3, in May . NB UK Year 3 is the same as Singaporean P2.

I am concerned that he is not able to master a question as follows. I want to ask fellow parents of P2 Children whether this is a normal P2 problem-solving question? In short should I be worried that DS1 cannot attempt it, even when I explained it to him.

The question is linked below. Please excuse the poor scanning, showing a grey shadow to the right-hand-side. Also, ignore the workings out, as I forgot to rub them out.

DS1 struggled on Part (a) for which the answer is 52 (28 + 24 seats).

Can anyone respond on 10 April, please, as we jet off for a holiday to Mexico on 11 April - for two weeks. Althhough, I most probably will log on when I get there.
