How to better understand the problem of difference multiple in primary school? What do you think?

If you want to better understand the difference problem in elementary school, you should understand the meaning of the question correctly. As long as you give the right judgment, you can find the right way. In the problem, it is necessary to find several times who is in harmony with the other, and such words can play a key role in solving the problem.

Through these, it is known how much is different from whom, and how much more is than whom. Children are the easiest to confuse between multiples and multiples, and parents must gradually analyze the problem for their children. When doing the questions, you can really understand how to use it, and parents should not be too anxious about their children.

When the teacher explains the problem of difference to the child, he will first determine the multiple or the double amount. This method is to draw a line segment diagram of the multiple relationship first, and then look at what the proportion is after it is determined. In fact, you can see these words in the question, whether you like to do addition or subtraction, you can get the result.

Put all the multiples on the ** paragraph diagram, which will be particularly intuitive at a glance, which is convenient for each teacher to analyze and understand. Only by finding the corresponding multiples can we really calculate it, and it will not be affected in any way. <>

Some children will find that there is usually a corresponding multiple plus 1 or multiple minus 1, which is very important. Only by finding the corresponding relationship in the process of solving the problem can we get an accurate answer. You must be good at finding known conditions in the problem in order to get the initial desired result.

It is necessary to meet all the conditions, and it will be more intuitive when analyzing. <>

In general, the child has just entered primary school and has been exposed to the poor times, and the problem must be very difficult, and parents should not always scold their children loudly. It is necessary to give the child a process of adaptation, so that the child does not feel that learning is a boring thing. Every child may not understand the thinking in mathematics, and parents must be good at guiding them next to their children.

Explain the basic knowledge to the child, and the child will be able to understand how the knowledge points exist.

It is a problem of difference multiples, that is, the relationship between the divisor and the dividend. I think it's easy to understand, and as long as you can understand the definition, then you can calculate better.

You can understand the multiplier relationship between these two data by drawing a line segment diagram, generally the decimal is divided by the difference by the multiple minus 1, and then the large number is multiplied by the decimal multiple.

The difference problem is very misleading, and the child needs to find a certain trick, and he must read the question carefully to analyze what it is?

It's not to give again, if it's to give again, it will be clearly written to give again.

Xiao Ming gave Xiao Hong 8 sticks, and the two of them had the same amount of watercolor pens.

It shows that Xiao Ming turned out to be 8 * 2 = 16 more than Xiao Hong.

Xiaohong gave Xiao Ming 8 branches, so Xiao Ming had 16 + 8 * 2 = 32 more than Xiao Hong. At this time, Xiao Ming's watercolor pen is 3 times that of Xiao Hong.

So, at this time, Xiaohong has watercolor pens 32 2 = 16.

Xiaohong originally had 16 + 8 = 24 pieces.

Xiao Ming originally had 24 + 16 = 40.

If Xiao Ming gives Xiao Hong 8 sticks, then the two have the same number of watercolor pens, indicating that Xiao Ming has 8 + 8 = 16 more than Xiao Hong.

If Xiaohong gives Xiao Ming 8 branches, then Xiao Ming will have 16 + 8 + 8 = 32 branches more than Xiaohong At this time, Xiao Ming is 3 times that of Xiaohong, and 2 times more than Xiaohong, so at this time, Xiaohong has 32 2 = 16 branches.

Therefore, Xiaohong originally had 16 + 8 = 24 branches.

Xiao Ming is 24 + 16 = 40 branches.

The conditions in the original title were separated, two assumptions.

Solution: Xiao Ming originally had x watercolor pens.

Little Red originally had Y watercolor pens.

x+8=3(y-8) ①

x-8=y+8 ②

by x+8=3y-24

x-3y=-32

by x-y=16

① 2y=48

y=24 When y=24, x=40

A: Xiao Ming originally had 40 watercolor pens.

Little Red originally had 24 watercolor pens.

8*2*2 32 (branches) 32 (3-1) 16 (branches) 16*3 48 (branches).

Little red: 16+8 24 (branches) 24+8*2 40 (branches).

Answer: Xiao Hong has 24 branches, Xiao Ming has 40 branches.

No, Xiaohong gave Xiao Ming on the basis of Xiaohong's original, and Xiao Ming gave Xiaohong on the basis of Xiao Ming's original.
