Maybe your parents started a little late to guide their children to learn math. When the child was practicing sitting, I began to guide him to learn to count. Before he went to kindergarten, he would do multiplication and division of two digits. Your child should not be in primary school yet, so you don't have to worry. Now before the third grade of primary school, it is mainly Chinese and math (I come from Shenyang, Liaoning, and now we don't have English before the third grade of primary school). Mathematics in Grade One (Beijing Normal University Edition) is very simple. You can teach him to add, subtract, multiply and know a few basic numbers in 20 minutes. You really don't trust. You can buy a math exercise book from grade one in the bookstore to give him time to practice more. These will do. As long as you are not careless, there is no problem getting a hundred points in the exam.

The key is that you should be patient. If your child makes a mistake, you will be anxious and angry. If you are angry, he will be afraid and nervous because of his miscalculation. If you are angry, he will be more confused and even less. Children really can't understand the troublesome problems. Just put it aside and do something else, or simply take the children out to play. Don't get into trouble, relax and come back.
