It is very important that primary school mathematics exams often test applied problems. Students must master them. To solve the normalized application problems, they must understand the quantitative relationship and problem-solving thinking skills of these application problems.
Similarly, to solve this part of the application problem, we must find out the quantitative relationship of the inductive problem and then answer it according to the quantitative relationship. Sum-difference application problems often appear in middle school mathematics midterm and final exams.
Primary school application problem skills
Quantitative relationship refers to the relationship between known quantity and unknown quantity in application problems. Only when the quantitative relationship is clear, can the algorithm be properly selected according to the meaning of the four operations, and the mathematical problems can be transformed into mathematical formulas and solved by calculation. Quantitative relationship analysis method is divided into three steps:
1, find the number in the problem.
2. Make clear the quantitative relationship.
3. Solve all the problems that arise.
When parents help their children with homework at home, they can refer to the teacher's guidance method, teach their children the angle and method of thinking, and develop the good habit of thinking independently and answering quickly.
