However, my ds and myself prefer using simple simultaneous equations ( using units and parts ) to solve such questions. How did the mainstream teachers teach the students in solving such questions?
Ummm... they teach the textbook and the worksheets he gets are very straightforward model method can easily solve type.
He picks up the other methods on his own and just plays around with them. Last year, I forced the mastery of models on him with a resource I found. He wanted to use branching and some other heuristic but I made sure he mastered model. It was really really weird. He was very stubborn. He did the same question TWICE. Once with model because I forced it. Next with his own method because he just wanted to.
Now, he just picks what he thinks is fastest. Or a combination. -

Yes, speed is very important. There are many bright students who can finish the PSLE Maths Paper in one hour. Hence they have plenty of time to check. What I heard is many scored full marks too. This is how good some students can be.[/quote]We're nowhere there I'm afraid. He has so far only been able to get 93 maximum (because of carelessness) and has only 20 minutes to check at most.Chenonceau:
[quote=\"PiggyLalala\"]However, i believe there are alternative ways of solving these questions without using simultaneous equations. I think models can work for such questions. Mathizzfun in the PSLE Math thread is very good in drawing models and solving questions using models only
What he tries to do is to try out multiple methods so that he has a sense of each method. This gives him some sense to choose the fastest method during exams. Depending on the question, the method used can save a great deal of time. Sometimes, it's branching. Sometimes, it's algebra. Sometimes, it's model.
Speed is important in PSLE. The faster you solve, the less mental energy you expend. This means your stamina is better too. Stamina is important too. -

ds does not use branching or model. I think most questions can be done using units and parts and simple equation. Yes, sometimes simple simultaneous equation to get rid of unknowns. It is not tough, because every step is logical.PiggyLalala:

I'll keep this advice in mind going forward. School hasn't taught simultaneous yet so he's learning on his own with a secondary textbook.

Questions on speed and area can be quite tough too.

These no problem as yet. Circles is what kills him. We had to buy a Math Olympiad book to get some practice there. -

Btw, the GE also did not teach the kids on solving simultaneous equations.

See lah... that's why my son's ex best friend JJ, in GEP, has to go for tuition too!!!!!!!!
