Q&A - P3 Math

[smartmummy]

Hi everyone!

My p3 son always does careless mistakes.I sick of it.In primary one,first question "more" then following question "less" then add for this also.In primary2 first half,he + for subraction and - for sum,and calculationwrong copying numbers from part a to part b.Then I give more prctise and let him knows why he got wrong those questions.Then second have he didn’t get any careless mistakes.Then now primary CA1 exam,copying the numbers from the questions he got wrong,other than that all calculations and models he got correct.SA2, for 1600 he chose 16 thousand instead of 16 hundred,…multiplication error 22 for 32, copying the number from a question 3 for 8.copying the numbers from question is not related just any number he put.Why like this?Is anyone face these problems?Please give me some suggestion to improve him!:( Thanks in advance!

I think so,he is very playful.He always think that he doesn't have time to finish.Actually he can finish,but at home he never do a paper from begin to end.He finished by three days.He has lack of practise.Now I start to give a paper and ask him to finish.very lazy to study.

thanks for your reply.

It seems that your son is prone to copy the wrong numbers from the question. Maybe you can suggest to your son that the first thing he should do in the test is to check that he has copied the numbers correctly before proceeding to solve the sums. Maybe he can highlight or underline the numbers in the questions. Of course he should not rush through each question. Good time management is very important. To do well in Maths, you must have both the speed and accuracy.

Hi,

Please help me with the below questions. I do not know how to draw the model. :?

The length of the rectangular table is 3times its width. If the length was 2m shorter and width, 80cm wider, a square table will be formed.
What are the dimensions of the rectangular table?

Thanks all parents for the help in advance

Length = XXXXX XXXXX XXXXX
Width = XXXXX

Difference = 2M (200cm) + 80 cm
Therefore 1 unit = 140 cm

Dimension of the table is 420 cm x 140 cm

After he did one type of careless mistake then I tell him what you have to do.then next time he will do another kind of mistake.I have to remeber/know all possible careless mistakes and remind him before the every exam.I need a journal book for him and i need to keep that.otherwise i gorget.

Thanks for your reply!

In this question, it is important that the child knows that the sides of a square are equal, that is the length and breadth of a square are equal.
Hence, when 2m is removed from the length of 3 units and 80 cm is added to the breadth, the remaining length and the new breadth are the same.

The child must be able to extract this 'hidden information' from reading the question. After which he should try drawing the model. With the correct model drawn, the question can be easily drawn.

[PiggyLalala]

Length:XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX

New L :XXXXXXXXXX XXXXXXXl<------- 2m -------->
Breadth:XXXXXXXXX
New B : XXXXXXXXX<-80cm->l

When drawing the model, one has to rememeber the hidden information in this question, one has to ensure that the new Length and breath must be of the same length in the model.

therefore 2 units = 2m + 80 cm = 200 cm + 80 cm = 280 cm
1 unit = 140 cm
Diamension of the rectangular table is 420 cm by 140 cm
