[quote=\"janet_lee88\"]In any case, she should not embarrass my boy by telling him to repeat what she had said IN FRONT OF WHOLE CLASS. My boy was so mad with me. Is there a problem being pro-active ? :x

If this happens to my boys, I wld definitely thank the teacher (with a hint of scarasm) for such \"valuable\" opportunity aka public speaking skill training and also encourage her to give this chance to other pupils.

Sh!@, I was so mad when my son told me that. Bcos of not wanting my son to get more shit from her, I have to control not informing P...anyway, I doubt P will understand me and 99% side with her subordinate.[/quote]Remember I posted some time ago about shaming the pupil for silly mistakes in MA worksheets? I brou up this issue to the MA teacher at the PTM on whether names were really put up. Turned out my boy was wrong to say the name wld be flashed out on the visualisor and silly mistakes are not careless mistakes.

What are silly mistakes? An example:
All along in model drawing, we will count the no. of units and write the working as X units = YY. Turned out this year MA teacher taught X units -> YY. If the pupil continues to write X units = YY, this is considered a silly mistake.

On the spot, I informed the MA teacher that since P2, none of my boy's MA teachers had taken an issue with how the working was written. So all doubts were cleared.

I am surprised that this is taught only at P4. Arrow sign should be used to represent units in the model the moment the kids start to learn models. It will be penalized if equal sign is used instead cos the UNITS are relative representation of the value. Equal sign is used strictly if both sides are VALUES equating to the same.

I was surprised too. Even Fabian Ng's PSP did not highlight this. All his examples use '=\" sign.

What abt your dd's P2 MA teacher? Was this '->' sign already taught then? What abt this year P3?

What abt your dd's P2 MA teacher? Was this '->' sign already taught then? What abt this year P3?[/quote]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.

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.

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.

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.

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.

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....
