The description of this problem is a bit vague. I don't know how old the child is or how fast it is!

The requirements for kindergarten children and first-grade children are also different.

My family is in the middle class of Dabao Kindergarten, but the addition within 20 and the subtraction within 10 are very good, please share!

1. First of all, children should be familiar with numbers within 100, and at least master numbers within 20.

If children want to learn addition and subtraction within 20, they must first master the numbers within 20. The more familiar numbers are, the smaller 20 is for children, and the easier it is to calculate, which makes them feel that "other mountains are dwarfed by the sky". Psychologically.

2. Teaching addition and subtraction in daily life scenes

Life teaching, flexible learning and application is the simplest and most solid way.

For example:

Q: My brother has 1 apples, and my brother is all apples. How many apples are there in a * * *? A: Two. Parents "Yes, 1+ 1=2".

Another example is:

Q: One * * * boiled four eggs and my mother ate 1. How many eggs are left? A: Three. Parents "Yes, 4- 1=3".

There are many such scenes.

3. Provide electronic products similar to point readers.

I have a point reading machine at home, which was given by a friend. I have never been interested in this kind of electronic product, and Dabao occasionally takes it out to play.

One day, Dabao was playing there with a number card. I just heard it and said, "What is 8+4?" Then I saw Dabao snapping the index, then pressed 12, and then clicked on the reader and said, "Yes, you are great!" "Dabao very happy, and then continue to break your fingers, continue to add and subtract.

Suddenly found that the point reading machine is also very good! I have never taught Dabao. He calculated it spontaneously.

4. A wall chart can be provided.

The function of the wall chart is to provide a possibility of interest, and it probably acts like a toy. When you hang the wall chart there, there will be some moments when children will be interested in watching, reading and calculating.

5, the game play, refused to force.

The younger the child, the less you can force the child. Must be tangible and intangible, quietly resolve things, learn in life, and let children understand deeply and thoroughly. Understand the essence of the problem, and the child will draw inferences.
