No lah, They are not genius. They ask me what the question was as everyone was talking about it. They dunno how to do but I just showed them how its done using the method taught by their maths teacher. Took me some time to figure it out too. Using algebra would be easier. :sweat:
Being my daughter's tuition teacher since P1. Direct algebra method is more difficult than modeling. Pls refer to my earlier post.http://www.clubsnap.com/forums/showpost.php?p=5537115&postcount=24
All the while I have been following MOE method, and teaching base on their textbook. Hence, solving such questions using modeling is the easiest and quick.
Many parents always tried to "reverse engineering" or relate to their kids using Algebra. Unfortunately, such question is not design that way. For the time given during exam, modeling will be the fastest and lesser mistake.
So, my advice to all parents if they want to teach their kids, it's better to re-learn their method and coach them base on what they are taught in School. They will be happier and able to absorb better.
Cheers!
