Q&A - PSLE Math

[Muffins]

Hi Tianzhu,


this is the working for Q1 (i think!)

Assuming that the no. of days if they want to be on time is "y":

6 x (y-1) = 4 x (y+2)

6y – 6 = 4y + 8

2y = 14

y = 7

7 – 1 = 6

6 x 6 = 36

Hi


Just to check with parents and students here : is it ok to use algebra to do problem solving questions at P6 level ?
I've posted this question in the PSLE 2011 thread but thought I would post it here since some parents/students here have already tried doing the 2010 top school papers. One parent has advised to use model method.

Pls advise because all along I thought schools are using the model method / unit transfer method (actually how many methods are there :oops: )?

Thanks in advance.

Hi


Algebraic expressions in one variable is covered under the topic of Algebra in P6.
http://www.moe.gov.sg/education/syllabuses/sciences/files/maths-primary-2007.pdf

The question is after learning Algebra in P6, is a student fully equipped with the skills to cope with word problems using Algebra (taught within syllabus)?

Without going beyond the syllabus, can a student use Algebra effectively to solve word problems ?

Do students need to accelerate their learning of Algebra through external courses (tuition/enrichments) or parents to enable them to use Algebra to solve word problems ?

Every child is unique, they have different leaning abilities. Not every child has the luxury of additional tuition.

Let the child decides, the golden rule is to use whichever method a child is comfortable with to solve a question.

Here’s a reply from MOE on Different Approaches Taught for Mathematics Techniques
