Teaching the child to share a bar begin in the third grade. By this time, the schoolchild must already use the multiplication table with ease. But if there are problems with this, it is worth immediately tightening up the knowledge, because before you teach the child to share a column, there should not be any complications with multiplication.
How to teach to divide a column?
For example, take a three-digit number of 372 and divide it by 6. Choose any combination, but so that the division goes without a trace. At first this can confuse the young mathematician.
We write down the numbers, separating them with a corner, and explain to the child that we will gradually divide this large number into six equal parts. Let's try to divide the first digit 3 into 6 first.
It does not divide, and therefore we add a second, that is, we try, whether it will be possible to divide 37.
It is necessary to ask the child how many times the six will fit in the figure 37. Those who know math without any problems will immediately guess that by selecting the method you can select the correct multiplier. So, let's select, take, for example, 5 and multiply by 6 - it turns out 30, like the result is near 37, but it's worth trying again. To do this, 6 is multiplied by 6 - equal to 36. This is suitable for us, and the first digit of the quotient is already found - we write it down under the divisor, behind the line.
The number 36 is written under 37 and when subtracting we get unity. It again is not divided into 6, and therefore, to her we demolish the remainder of the top two. Now the number 12 is very easy to divide by 6. As a result, we get the second number of the private - two. Our result of division will be 62.
Try different examples, and the child will quickly master this action.
