Tips for improving in PSLE

[kitty2]

I wonder whether the PSLE kids can use Algebra to solve the problems?


Thanks

Can as long as the student can present his workings properly to convince the markers that he/she knows what he /she is doing.

Well,ratio problems are supposed to be solved by ratio.I love using ratio but i'm always stuck at challenging questions that involve ratio.One quick(inaccurate) example is this: The marbles that A and B has is in the ratio 6:7. Then,124 marbles were added to the total and the ratio became 2:3.How many marbles were there at first? These kind of questions are common and its almost impossible to solve using model. If your dd knows how to use ratio to solve such challenging problems,then your dd should be alright if she wants to use model now as she still have the \"skills\" to apply the ratio method if she needs it.However,if she cannot solve using ratio,then she may face difficulty with the challenging questions.

Hope this helps.:)

Hi Vanila

I understand that fraction is closely related to ratio.My girl refused using ratio to solve ratio prob but always use model to solve it instead.Do u forsee that she will zoom into bigger prob?thanks
[quote=\"livewith_vanilla\"]Fraction,ratio and percentage are connected.Usually,if you can understand how to do one of the topics and are able to convert like say percentage to fraction,you can easily solve the problems.Drawing models is also helpful. In my opinion the few most crucial topics are volume,area and perimeter,speed,circles and percentage.

Hope this helps!

Could you pls advise the source of your question as there seems to be more than one possible correct answer and what do you mean by saying: \"One quick(inaccurate) example is this:........\" Pls also help to share your solution for this question as your feedback will be useful for my younger sister who will be taking PSLE in 2011.
Thanks.

By the way if the student wants to use algebra, must remember to write a statement defining all variables not stated explicitly in the question, otherwise there is the risk of marks deducted.

Thanks.[/quote]Sorry,but I left the solutions to such similar question in school.May i get back to you on Monday or Tuesday after i retrieve my worksheets or have a word with my classmate(who is a mathematics genius and introduced the simple solution(if you can understadnd it) to our class).Thanks and sorry for the trouble

Hi livewith_vanilla,
Pls refer to discussion about your question in this http://www.kiasuparents.com/kiasu/forum/viewtopic.php?t=280&postdays=0&postorder=asc&start=1250. It is not about how readers in this forum can understand the simple solution introduced by your classmate who is a mathematics genius or not. It is the way your question is phrased as multiple correct answers will surface as your question is too vague. If you don't mind, pls advise the source of this question and let us (readers) know.

Ermmm...sorry but that's not the question i have actually.I actually just thought of some random one.It is not actually a question.Its just an example,something that i just thought of randomly without any thought.Yes,the answers will be vague.I will take an example from my school paper tmr and post it here as an accurate question with only one answer.Sorry!
