Use Algebra to solve problems for PSLE Maths
-
What is model drawing in our time? We had never ever use model drawing but yet we passed through our PSLE in using algebra method. And it does not mean that model drawing would be useful for them in Secondary school and they do not use it at all! Another words, model drawing is only applicable for Primary levels which I feel. :roll:
Most Secondary level is using mostly algebra method to solve maths problem. So it made no difference of using algebra method now in P6 and Secondary level. -
My P4 son has problem doing model drawing. The more he draw, the more mistake and usually he will get zero for all model drawing. So I have no choice but to teach him units method and algebra which he find it much easier to comprehen. If without the skills of model drawing, will he face lots of problem in P5 and P6?

I can understand the frustration some parents face when using model drawing to solve primary school maths problems.
I belong to the era where model drawing was taught and was NOT taught any algebra until secondary school. The concept of model drawing is deeply entrenched in my mind, thus when my dd1 started model drawing, it was easy for me to teach her model drawing since I learnt it before. However, my DH had problems as he belongs to the era where only algebra was taught in primary school. I observed that he tended to use algebra to explain and I could see his frustration with model drawing so I ended up teaching my DD and DH about model drawing.
After some time, DH got the hang of model drawing and is now able to use it proficiently to help the children. In DH's view, model drawing is a good way to introduce abstract concepts to children and helps them to effectively visualize mathematical problems.
For example, the statement about child A having 3 times as many sweets as child B is abstract for a 9 year old kid but will be easy to visualize by drawing out the model.
Just have to be prepared to unlearn algebra and learn about model drawing from scratch. -
The beauty of MOE syabullus is learn Models for Primary School Maths n then when you enter Sec School, throw it back to your Primary School teachers n start learning Algebra becos you don't need to use Models anymore.
To me, MOE only think of short term n not long term. I really do not understand what is their rationale to make kids learn Models only for Primary School n then unlearn n relearn Alegbra.
Oh well, MOE hires scholars to design the syabullus for PSLE, rite?

Perhaps we can try to stop viewing model drawing and algebra as separate and unrelated methods. Model drawing simplifies the introduction of abstract concepts (such as let the unknown variable be x) and could be viewed as an introduction to algebra. Model drawing makes it easy for lower primary school children to visualize about unknowns as well as break down a complex problem into simpler parts.
Drawing models and having to work with units will ease the transition to the next step of stating "let the unknown variable be x". Moreover the habit of drawing to visualize a mathematical problem is a good habit and will come in useful when handling more abstract mathematics like vectorial calculus. -

It maybe good for lower Primary but not necessarily for PSLE.
My kids struggled with Models n its a real frustration for them for PSLE maths.
Now they are in Sec School/JC, they tell me that Primary School Maths is so tough n non applicable for them now. They are much happier now. -

Model drawing is supposed to help primary children to break down complex problem into smaller parts using visualization. Now that you mention it, I realized that the problem may not be on model drawing itself BUT rather the way section C questions are formulated. Far too convoluted and divorced from the reality!lee_yl:

For example, nobody in real life will pose a statement like this, \"today i spent 12/15 of my money on this and half of the remainder on that and another 25% blah blah blah, finally, I am left with twice as much as Cindy. How much does Cindy have initially?\" :slapshead: I think secondary sch maths are more realistic. -
anyone know which P4, P5 or P6 Maths textbook (title, author or publisher) teach Algebra ?
because can find Algebra in Secondary Maths text, but a bit chim to P4, 5 students. Thank you, very much, for kind sharing -
Agreeable to Twinkless and Zbear review. Pardon me of saying, I find it really senseless to use model drawing for PSLE. Like the other parent mentioned in the previous forum, let the kids decide which methodology is more comfortable for them. Like what Zbear has mentioned, you have to throw back the model drawing to Primary teachers and start learning new method in Secondary level. Why making it so confusing for the kids ? They already felt so stressed up on daily work and exams. I don’t understand why add on extra burden for them. Give them a choice to choose.
