question about maths problem sum
-
ksi:
hence the emphasis that good english is needed for good math scoresAssuming you mean 5 baskets and each has 8 eggs.
This is 5 groups of 8 = 5 x 8
8 x 5 is 8 groups of 5.
Mathematically, the commutative law states that:
5 x 8 = 8 x 5.
However, when children are learning concepts of multiplication, the teacher will teach them to understand 5 groups of 8 is 5 x 8 and 8 groups of 5 is 8 x 5, hence at that learning stage, the child has to note the difference according to English. I suppose this is teaching the child how to interpret the Math from an English statement so following the English specifically is required at this stage of learning. As they move up and understand the commutative property in Math for multiplication, then both can be used interchangeably as they solve problems.
If I am not wrong, at P2 when this is learnt, there are worksheets to ask the children to write what is 6 groups of 8 and they have to put as 6 x 8 and not 8 x 6 -
sorry for typo error. it shd be like what ksi assumed. 5 baskets, 8 eggs. thanks for pointing out.
hi ksi thanks for your detailed explanation. I can now understand. I used to tell my son there's no difference between the 2 number sentence as you get the same answer ultimately. guess I have to be more careful.
thanks again for your great help.

True to say that you need to have knowledge of English to interpret the Math question written in English into mathematical symbols to be solved. This training is mainly required for PROBLEM SUMS.

This is where our kids learn the exam-paper smart part if a child is already very smart in knowing the commutative law or for advanced kids.
If it is a worksheet or topical test or the year they are being tested for the learning concepts of x groups of y, then they have to be careful which one comes first. After bypassing that stage, it is fine. In other words, come PSLE, this would no longer be an issue.
