Application problem has always been the most troublesome reminder in mathematics problems, which not only tests children's mastery of basic knowledge such as mathematical concepts, laws, formulas and problem-solving methods, but also requires children to have the ability of analysis, judgment and reasoning. Today, Teacher Wang will briefly talk about how to solve application problems.

First, look at the topic clearly. Many children are careless when they do problems, and they start to do them without seeing them clearly. It's a pity to lose points like this. You must get into the habit of doing problems carefully. Another possibility is that children can't understand the topic and there may be problems in reading comprehension. This problem requires children to strengthen reading normally.

Second, we should clarify the thinking of solving problems. If parents help their children with their homework at home, they can try to teach their children the angles and methods of thinking under the guidance of teachers. Remember to let the children think for themselves. The following are some common ideas to solve different application problems, which can be collected for children.

Expand knowledge:

Application problem is to describe relevant facts in language or words and reflect some mathematical relationship (such as quantitative relationship, positional relationship, etc.) ) and solved an unknown number of problems. Each application problem includes known conditions and problems.

In the past, China's application problems usually required narrative to meet three requirements: no contradiction, that is, conditions and problems could not be contradictory; Completeness, that is, the condition must be sufficient to ensure that the value of the unknown quantity can be obtained from the condition; Independence, that is, several known conditions cannot be deduced from each other.

Mathematics application problems in primary schools are usually divided into two categories: simple application problems that can be solved in one step only by addition, subtraction, multiplication and division; Complex application problems that need two or more operations to solve.

In mathematics teaching, practical problems including some mathematical relations (such as quantitative relations and geometric figure position relations) are described by language or words, and the problems formed in this way are called application problems. Any application problem contains two parts. The first part is known conditions (conditions for short), and the second part is seeking problems (problems for short). The conditions and problems of application questions constitute the structure of application questions.
