Another PSLE Math Qn

Another question posted on my blog:

    Some hot Tiong Bahru Paos (buns) were placed under a transparent plastic hood. After a few minutes , water droplets are observed to be formed on the under surface of the hood. Explain why water droplets are formed on the underside of the plastic food cover.

    What is the correct answer for this question?

    Obviously, it is not a tough question. Even Primary 4 students can do it.

    From what I see, parents over-reacted over this particular question.

    I totally agree with teeeecher that it is a over-reaction by parents over the PSLE Math questions. This qn is clearly within a P4 Maths syllabus. While adults who are unfamiliar with models may be stumped by the qn, most children who are clear with the concepts of model drawing will find this qn a breeze (except those who were too nervous under exam pressure).

    Your sister is so clever to work out the PSLE difficult question! My child just looked at it and did not even try, saying that the question is too hard for him. By the way, your sister's ability seems to be beyond her cohort's, is she from the GEP as GEP kids are normally very smart.
