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.Hi

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. -

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. -

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.

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?
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.

I noticed my P2 boy does not do mental long subtraction by the right to left method. He uses the left to right method. Should I be concerned? No one in our family taught him the left to right method leh. Addition wise is right to left. Why subtraction left to right? I dared not ask him for fear I confuse him. Should I just left him as it is since at the moment, it seems to work well for him?
