Hello Friends,

    I need advice regarding this simple division method.

1) Is this process correct ?

2) Is it a good way to teach children ?


Example in attachment.....


Here is the explanation of the process.....

1) We have been given a problem of dividing 2/100.

2) We see that 2 is smaller than 100 , so we have a problem.

3) We like sweets and we know that placing a point gives us a sweet.

4) We put the sweet beside 2. Now we know that 100 goes 0 times into 20. so we put 0 in the quotient.

5) Now 20 in the remainder, but we are hungry again so we want another point.

6) While we try to put the point we see that a point is already there so we take a sweet and place it beside 20 to make it 200.

7) Now we put 100,2 times i.e. 200.

I will be waiting for your valuable additions ...

If you want children to learn what 2/100 is, you would be teaching to I think 10 or 11 year olds. Right? In my view, these youngsters already see themselves as quite smart, and they do not get amused if you distract from the bare logic with candy stuff. At least I was that way when I was 11. But I was not like most children ... maybe. In the whole story to me the whole 'candy but we are hungry' fringe is confusing. Just write how it is, these kids are often smarter than you think.

Thanks Jan. You are correct. You know what, though my 10 yr old girl can do all the maths I teach, but still she does not like maths. And I see myself as a failure if I cannot make her like this beautiful subject. Don't know what to do....

bhaskar, do not be to hard on yourself. I think only one single ten year old girl in a hundred likes math. ;)

I was a lot younger than ten when I learnt that sort of division. It is, by the way, long division not short division.

And if you think a liking for maths is rare among ten‑year‑olds, that's because you haven't asked any older females about maths

  • 1: 100 into 2 won't go, so add .0 to the text of the dividend and see whether that will go. Put 0 as the result and shift the divisor to the right.
  • 2: 100 into 20 won't go, s add a 0 to the dividend String and .0 to the result and shift the divisor to the right. You now have 2.00 in the midde and 0.0 on top.
  • 3: 100 will go into 200, in fact exactly twice, so add 2 to the result text, and subtract 200 from the divisor: this gives a difference of 0 which shows you have completed the division. The top line now reads 0.02 subtract
