P2 Math - General Discussion

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.

Hi,

Anyone here know whether is working required or expected for Maths problem sums these days? Can just give answer without doing working? If answer correct but no working, will it still be a full score for the answer?

In addition, I need help on the WORKING for the following problem. Really hope someone here could help.

A shop sold oranges and apples packed as follow.
bag of 10 oranges. (A diagram is printed showing a bag with 10 oranges)
bag of 5 apples. (A diagram is printed showing a bag with 5 apples)
For every 10 oranges Madam Esah bought, she also bought 5 apples. She bought 20 oranges. How many bags of fruids did she buy altogether?
(Hint : Draw a diagram to help you solve)

Anyone know what is the kind of diagram expected for P2 Maths working for this kind of sum? My son can get the correct answer but just couldn't draw the digram. And I also can't help him either. Anyone here can help?

Heyya usaik,

I usually just ask my kiddies to do all workings.
So in case the answer is written wrongly or carelessly
written wrongly, the diagrams, drawings or picture workings
will still carry marks for the questions. So rather than an ultimate
zero, there'll be some \"save\" marks for them. If the instructions
clearly states, please indicate working..... then definitely must include
lah but compulsory or not - that i'm not sure... Mebbe it varies between
schools? I find that a complete working also helps to show that the answer
was derived from her own train of thought and not glimpsed and copied
from next-seated-neighbour...

If this question requires a diagram, (and a school question) - the textbook
would have shown the children (and parents) how the workings have been
introduced to the children to do in class. Mebbe you can ask him if the
teacher has done so and also flip his Maths Textbook..

As for the workings and diagrams, it could be ...

There can be other versions too.
If other parents can share, i'd love it too! :please:
Hope to learn from one another here, to help our kids better.
Thanks in advance and much appreciated.

My P2 boy tried this qn today. He drew a 2 rows by 2 columns table to indicate 1 bag of orange + 1 bag of apple, followed by 2nd bag of orange + 2nd bag of apples. He then answered she bou 4 bags of fruits.
