Q&A - P3 Math

[HAPPYH]

Hi all,


I need help with the following question.

How many 4-digit numbers can be formed with the digits 4, 6, 0 and 5? If there is no 0 given, then it will be 4 x 3 x 2 x 1 = 24 numbers. If there is 0, is it just 3 x 2 x 1? Thank you in advance.

I agree with WCW’s answer.



I also have a question that I find difficult to teach and make her understand. Can anyone help?

Henry has some apples. When he puts them equally into boxes of 3, he will have 5 more boxes than if he puts them into boxes of 4. How many apples does he have?

I usually reserve "guess and check" method as the last resort. Any alternate ideas?

Hi

If such questions were to appear in P3 level, usually students would use “Systematic Listing” to solve it.It’s quite tedious.

Assuming no repetitions of number and 0 cannot be the first number.
\t
The first number can be chosen in 3 ways.

We can choose the second number in 3 ways.

The third number in 2 ways and we are left with one choice for the last number.

3*3*2*1 ----- 18 ways

Help. Frantic advice for DS1 and DS2 needed.


Am I doing the right things with DS1. He has completed the first term of his P3, and struggles with Challenging Maths P3 by Sataya Sundar (EPH). Is it conceding defeat for me to take him back to the P2 book (which we did not complete), and for him to complete that before progressing to P3 again.

I will turn to DS2 in the P1 section.

I also have the same feeling. No matter what/how I taught my DD, she still does mistakes with some questions. Sometimes, careless and sometimes she really does not know. We should not take it as a failure. WE should let them keep practising. If the Challenging Maths is a struggle, you sit with him and go thro' some problems. Over the time, he should be fine with it. It reminds me that my challenging maths is sleeping in the bookshelf. Must pass it to my DD to see her reaction as well as to see her level of understanding

My son in P4,he can do the normal qns.But I feel the qns in Challenging Maths P4 by Sataya Sundar (EPH) are very challenging.I just put the book away and planned to teach in the June.
Maths need lot of carefulness.My son any how do with given numbers,never think what is the qn.We did from the topical papers.
Now I planned to give the top school papers.After that may be I can try this book..

I find the Challenging Maths for p3 too challenging.. therefore, i hv kept it aside and just use the Maths challenging problems to coach him.

Just to check, I am very confused with the problem sums that contains desciption such as 1) as many as 2) thrice as much 3) twice as many 4) 4 times as many etc…etc…


How do I know for example the as many as refers to who? Like Lisa has as many marbles as Derek. So does it mean both of them has equal no of marbles?

Anyone can tell me if there is a easy way to identify the subject?
