P2 Math - General Discussion

KSP:

If not 33 then I really don't know what other answer it can be..... :?

The original question the ribbon was more folded so it created the feel that the length was as it was the folded length. So a possible way of looking at it would be including the folds, hence shorter.

Another tricky one for P1 level…ordinal question


Building with a few levels:

Level 5: Chairs
Level 4: Tables
Level 3: Sofas
Level 2: Benches
Level 1: Swings

One of the questions:
1. The ________ are found 2 levels on top of level 2.

If the answer is tables, it is correct.
If the answer is Tables, will not get full marks, 1/2 mark will be taken off.
They just want to test the children if they know their punctuation, capital or non-capital letters in a sentence.

So parents, please ask your child to watch out for English rules.

Me too think it is 33, it can be correct or it can be wrong=too tricky.

Now P1/2 maths is no loner the straight forward like what we studied. School only teach the skeleton. The rest will fall back on the child's own little brainy to think.

Not an easy subject anymore. Its an IQ maths lesson. Agree?
Kids needs to be expose to all kinds of books and not only their text book. Alot of all these brain brain teaser are from magazines for kids and also website.

I also feel that it is more tricky and English plays a big part now......I suppose they are training them to be sharper at a younger age. Not a bad thing since losing marks at P1 and P2 is not as bad as losing it in PSLE.

I like to share this website abt Model-drawing for Maths.

Hi


Does anyone have difficulty in explaining before and after to a P1 kid?

According to my dd, the teacher says before = in front and afer = behind.

The problem will arise in the following example -

15 is comes before ____.

Her answer is 14 as 14 is in front of 15. We asked her to list the nos before and after 15 and position herself from thereon but the offchance she gets it correct is from quessing. .

Is this type of questions common? My concern is that she would have problems with the positioning questions

Appreciate any suggestions. TIA

Children are confused because of the blanks, sometimes in front, sometimes behind... LOL I think adults also can be confused.

1. ____ comes/is before 16

2. 15 comes/is before ____

3. ____ comes/is after 15

4. 16 comes/is after _____

If a child is very confused because of the boxes, 1 way is to use this rule regardless where the blank is. Let a be first blank and b be second blank.

Before ----> always arrange the number in small to big sequence ->
(a-small, b-big)
After -------> always arrange the numbers in big to small sequence ->
(a-big,b-small)

Test on above questions.
1. Before, number given is b so it is big, then a must be small=>15 (15,16)
2. Before, number given is a so it is small, then b must be big=>16 (15,16)
3. After, number given is b so it is small, then a must be big=>16 (16,15)
4. After, number given is a so it is big,then b must be small =>15 (16,15)

Try it and see if it works.

My son also couldn't grasp the concept.

Someone showed me this, supposed to be a P1 question but from a Hong Kong school:-


AB + B = BA

A=?
B=?

If your child can solve this without guess-and-check… congratulations! That would demonstrate a very good understanding of the relevant mathematical concepts.

89 + 9 = 98

Absolutely!
A = 8 and B = 9

Most kids I tried this on used guess-and-check. Only one child analyzed it in terms of place value and renaming.
