Q&A - P3 Math

[kiasimom]

Hi,


My child is in P3 this year. P3 will be learning division working. But I understand that they don't learn time table anymore. I wonder how easy for them to solve division working? Any P4 parents can advise? Thanks.

Hi je,

Multiplications and divisions should be taught in P2.

Didn't your child's school teach that? :?

By end of P1, the kids are to know the concept of simple division and multiplication. Some memorization is needed after concept has been learnt.


Reading through je query, I think je is concern over long working division. This is covered in P3 math. I just flipped through ds P3 math text book & yes this is covered in P3. Is this what you are concern about je?

EN, BINGO

They use skip counting at P1 & P2, no longer using time table. That's why I was wondering how they can solve the long division working easily...different from what we used to learn...

Hi ks2me,


Just wondering ... isn't there a difference betw \"3 times more than\" and \"3 times as much as\" ?

In mathematics, there is actually no difference between \"3 times more than\", and \"3 times as much as\". Linguistically, and for most common usage, they mean the same thing.

The number of apples is 3 more than the oranges. (if oranges is U, then apples is U+3)

The number of apples is 10% more than the oranges. (so apples is 110%)

The number of apples is 1/2 time more than the oranges. (so if oranges is 2U, then apple is 3U)

The number of apples is 3 times more than the oranges - it becomes ambiguous. Why?

\"more than\" means greater in size by a certain amount that can be expressed in different ways.

If the unit of measurement for the additional apples is \"3\", than the same unit of measurement apply to the orange - actual number.

If the unit of measurement for the additional apples in % \"10%\", than the same unit of measurement apply to the orange - 100%.

So I think there is no ambiguity.

Hi Dharma

From Maths456.com, Model Diagrams, I learned that there are differences between n times more stamps than …… and n times as many stamps as ……… where n is a number greater than zero.

Take for example Alan has 2 times more stamps than Ben.
For the MD, you’ll have one box for Ben and 3 boxes for Alan.

It’s available in Popular. Browse through it when you are there.
