Any child can remember this question?

My girl asking me abt this coz she says all her class mates different answer. And very different. For question (b)

The drawing question:
(a) draw a triangle with the same perimeter as parallelogram abcd
(b) find the ratio of parallelogram abcd to the triangle you drew.

My girl said the ratio of the area is 5:6

Thanks for sharing. Will tell her tomorrow. From what she shared earlier one of her classmates got 5:6, others 10:9, 5:8. She and one other got 1:1 but was so many varied answers.

Would this be the question that's stressing the students out?

My sis forwarded me this suggested solution to the question above. https://www.facebook.com/nicklebee.tutors/posts/4949062438454414

I don't recall the PSLE being this tough back when my child was in primary 6.

In the past, the T-score could be moderated if the cohort does badly overall. Not sure if moderation is still possible in the \"AL\" scoring system.

This question may seem difficult for parents who are not familiar with the new methodology of problem-solving.

For parents who are familiar with what this generation of students are learning, you will recognise that this question is simply a combination of model drawing analysis and assumption method.
e.g Instead of say 4 wheels/legs minus 2 wheels/legs x no of parts. For this case, it is 2.7g x no of parts (which is 40)

Well, it might be plausible that there has been a shift in how PSLE problem solving is taught. Just like how I remember learning algebra back in primary school decades ago, while my child was taught model drawing instead.

Helen and Ivan had the same number of coins. Helen had a number of 50-cent coins and 64 20-cent coins. These coins had a mass of 1.134 kg. Ivan had a number of 50-cent coins and 104 20-cent coins .

(a) Who has more money in coins and by how much?(2)

(b) given that each 50-cent coin is 2.7g more heavier than a 20-cent coin, what is the mass of Ivan’s coins in kilograms? (2)

My daughter managed to get this right but took her a while to figure it out.

Thank you for sharing. It is much easier to read the slides presenting the solution this way.

A blessed morning to all fellow parents!

Can any experienced parents/wise ppl in this KSP forum share their top tips for how to revise the coming CL papers with their DS/DD (i.e. what/where/which specific areas to focus on and speculated topic for this year’s pictures compo etc), please help… thanks a lot!

My DD answered 1:1 too[/quote]Hi, please kindly share the rational of 1:1. Thanks. :thankyou:

[Autumnleaf]

Thank you to all who have shared. I am not sure of the worked solutions, I am lousy at maths but guess those who enjoy can give it a go
