ReplyDeleteOI why all no eye contact de

ReplyDeleteYichieh has weird body language and accent and Qianhui kept giggling.

I dont understand their explanation for 16(b)

ReplyDeleteI DONT UNDERSTAND AT ALL~

ReplyDeleteWhy didn't Yi Chieh explain how he got the answer? Can he please explain ??

ReplyDeleteSo what do you do with the similarity?

How do you solve it?? Please note it √

I am not so sure about the explanation for a).

ReplyDeleteYingliang kept using the word er.

ReplyDeleteI think u do not nid to write out the statement to find out LCM of 432 and 324 again(2 times)

ReplyDeleteWhere do u get the 2^2 X 3^3 =108?

Please explain...

Regards and BTWFYI, I am Owen. Thanks for your concern and you will be blessed.

They forgot to put the X and W in front of the numbers and Qian Hui was just whispering and smiling uselessly AT THE PAPER! Ying Liang was a little rushed and hesitant in saying what he needed to say

ReplyDelete@gladys how u do the copyright symbol

ReplyDeleteokok let me add on on what i dont understand.why did you divide the number by their HCF?

ReplyDeleteYingliang was a bit nervous. He kept using the word 'er'

ReplyDeleteIt is a bit confusing and there is not much eye contact.

ReplyDeleteWhat are you talking about??????!!!!!!!!!!!!

ReplyDeleteNot very organised. But good explanation. U must explain that 'W' represents a whole no., but u al say that 'w', a whole number, sounds like there is such a number.

ReplyDeleteYing Liang kept saying 'uh' for about more than 6 times.

ReplyDeleteBy-MacSpicy

er is not a word

ReplyDeleteI am kind of lost during the explanation.

ReplyDeleteNo eye contact frm Ying Liang

ReplyDeleteI did not Understand set B

BTWFYI NEMO and CREST stop use BTWFYI BTWFYI!!!!

ReplyDeleteYingliang kept saying 'er', 'uh' etc.

ReplyDeletei cannot see the paper

ReplyDeleteWho is Cram??????

ReplyDeleteAdd on...

ReplyDeleteLike Yi Chieh only noe wat is happening.

Find the LCM of 432 & 324??

ReplyDeleteWhy is the question w and x, but your answer is w and y ?

ReplyDeleteThey did not start immediately and were talking among themselves for quite some time. All of them except Jia Qi and Yi Chieh were facing the board, and not the class.

ReplyDeleteJia Qi's voice was loud and clear, so that was good.

Everyone was sloppy in their stance until Ms Loh pointed it out. But Jia Qi was clear in speech. But as for Qian Hui, she just stood there and watched and did absolutely nothing at all. And why did you suddenly change your method by using LCM rather than the previous HCF? Please explain.

ReplyDeleteBTWFYI, I am Mark

what is qian hui and yo cheih doing?

ReplyDeleteWhy must it be the multiple that is the lowest?

ReplyDelete2nd time comments(27/1/11):

ReplyDeleteThe answer to b(i) is not written so Jia Qi needs to verify with Ying Liang.

They didn't show the poster but written on the board.

The explanation is fine except for ms loh question.

There is no explanation of finding the the index notation of the 324 and 432.

BTWFYI,I am Owen.

Jia Qi's voice was Awesome loud clear and confident

ReplyDeleteWhy divide the LCM by 432 or 324?

ReplyDeletewere slouching~... :(

ReplyDelete@gladys

ReplyDeleteMs loh type wrongly

Not so much eye contact.

ReplyDeleteWhy is the question w and x but your answer is w and y??

ReplyDelete©Yi De

Where is the working for the index notation of 324 and 432? And why some people stand there never do anything?

ReplyDeletei agreeeee with toby :(

ReplyDelete@ Yi de

ReplyDeleteMs Loh type wrongly.

©Owen

@Mattew We found the LCM as we need to make “w” and “x/y” the

ReplyDeletelowest as possible.

@Gladys I think Ms Loh type wrongly.

@Jonathan Thanks.

@Mark We changed to LCM as it has less workings and it would

be easier for you to understand.

@DNL Refer to Matthew’s

@ Owen The index notation is on the other poster.

@ Lovy 432w = a multiple of 324 = 1296. To find w, we divide 1296

by 432, which we will get w.

@Toby A bit only I think, we were standing so hard to slouch.

@Ryan I’ll try to make more eye contact in the future.

@Jia Jun Refer to Owen’s
