According to my elder boy, when representing units in value, must use '->'. Unless it is a clear cut algebra X represents a value and Y represents another value, then we can write X + Y = an absolute number.
Didn't heard of this \"->\" from my ds.S6169:
[quote=\"E3\"]
Maths Teachers are instructed to teach \"->\" years ago to represent the units in the model. P2's Math models are quite simple and straightforward, so can derive the number statement directly, eg. if 3 units in the model is represented by 9. The child can write 9 ÷ 3 = 3 to derive answer for one unit.For the P3 thinking skills worksheets that the FT assigned, there are questions involving answers from more complex models. I have to check with my dd whether it has been taught in class. I taught her to use arrow sign if using units to represent the value, or she can write the number statements directly. Students can show their working both ways and both are accepted at PSLE.
Another eg. in which arrow sign should be used is:
3 apples + 1 pear -> $2
That Means if you write 3 u=9, it will be marked wrongly in PSLE? I though Model is another way of Algebra, \"U\" is similar like\"x\" or \"y\".
If use \"A\" represent apple, \"P\" for pear, can we write 3A+P=2?
You might want to write to the MA teacher for a clearer explanation.[/quote]For representing units, the \"->\" must be used. I do not know how many marks will PH penalise but usually 0.5 will be penalised for the whole question if \"=\" instead of \"->\" is used.
As for algebra, like what Jennifer's ds had mentioned said, the unknown needs to be clearly specified in the working, like Let x be ... or Let y be ... . -
Thank you Jennifer and E3. Will check my ds’s math homework. Didn’t pay attention about this before. or may be ds always use the number statements directly during the exam, so didn’t notice got any mark deduction.

pm you, Jennifer and S6169.

I think it was really purely personality clash.... like 火星撞地球。She was very stern with my dd cos she wanted dd to do better, when dd put in just a little bit more effort, she was not impressed and dd had the impression that T disliked her... so the relationship just went downhill from there.... dd has to learn that to stop self-sabotage and be more objective (cos you're bound to clash with someone sometime in your life) and I think T should go for lessons on child psychology. :roll: Anyway, I have no basis to complain.... Good thing this yaer, dd's Ts are all ok....
I hate this type of Ts. Granted, not everyone is blessed with the ability to inspire, but at least don't demoralise our children. That's the least we can expect from Ts.JoeeYee:
She anti my dd lah, always pick on her, I think personality clash....
Dd very affected and totally gave up on her lessons, including handwriting also gone from very neat to illegible.
Each and everyone of us parents here have given our best shot to groom our kids as best as we could. So it's a big, big responsibility the Ts have. -
S6169:
Hi S6169, your ds and mine are in the same class (M1). I just asked mine, she said, it is true that Mdm Chen did say it has to be arrow, not equal sign. When she started learning model 2 years ago, it was equal. :roll: But, while working with her at home, I used arrow, so she has been receptive to both. Now, she said teachers changed their minds. :roll: btw, you got PM.

Yes, Just checked ds's math homework, he use the arrow sign not the equal sign. A blur mum never though this is an issue.

真的吗？ They would rather channel the staff to read the post here than to handle formal feedback? Have been sending them a few queries and feedback since beginning of the year, but all go down the drain, so upset. Perhaps will be more effective to post here.
serious boh....chop-chopJennifer:
Think you shld not mention the loop holes so clearly, sch staff might b reading this post too.
By the way, I've a DD in P4. -
HappyTurtle:
Welcome!! I also have a dd in P4.
By the way, I've a DD in P4. Finally! Most P4ers' parents here are with boys. :lol:

So it was not becos my boy's ex-teachers taught wrongly. I told the MA teacher at the PTM abt my boy's ex-teachers using '=' sign. She mentioned she wld let the lower pri lvl teachers know abt this. Hopefully, we see an overall change for the lower lvl pupils. -
P4 parents, do your child hv issues with the recent LEAD MA worksheet?
On Tues, my boy was doing a LEAD account MA worksheet on measuring angles. He laid a protractor on the laptop screen, found the degree and input the ans. Then he submitted the ans and checked the marked worksheet. Some of his ans were marked wrong! I was sitting next to him then and I am very certain that the submitted ans were correct.
He was very frustrated with the LEAD account worksheet.
What abt your child?
