1, read the question carefully and repeat the meaning of the question.

To some extent, the teaching quality of decimal application problems affects the mathematics learning achievements of primary school students in China, and even has a far-reaching impact on students' future mathematics learning level and ability. Therefore, it is very important to improve the accuracy of students' calculation of decimal application questions, and the examination of questions is the first and most critical step.

Many primary school students hold a contemptuous attitude towards decimal application problems, and pay insufficient attention to them ideologically, especially when examining problems, and mistakes occur from time to time. Examining the questions carefully and repeating the meaning of the questions is the most crucial step for students to do the whole decimal application problem well. Therefore, teachers should strengthen the cultivation of students' ability to read the stem and repeat the meaning of the questions carefully.

2. Multi-sensory cooperation helps students to correctly understand the concepts in decimal application problems and improve their abstract generalization ability.

Concept is the cell of thinking, and its production can not be separated from the thinking process of generalization and reasoning. Therefore, teachers should cultivate students to use a variety of senses to participate in concept understanding, help students to establish a correct concept of decimal application problems, and improve their abstract generalization ability.

For example, teachers can use modern teaching methods, especially multimedia to explain the classroom content, and participate in the teaching of decimal application problems through video, text, pictures and other forms, so that students can get comprehensive contact with vision and hearing, and increase their interest and ability in solving decimal application problems.

Attach importance to the analysis of quantitative relations and clarify the thinking of solving problems.

Analyzing the quantitative relationship in decimal application questions is essentially analyzing the relationship between conditions and problems, which is also the key link to correctly understand the meaning of the questions.

Therefore, teachers should try their best to cultivate students' ability to analyze quantitative relations, help students to clarify their thinking of solving problems, and lay the foundation for students to do decimal application problems correctly. In the teaching process, teachers should emphasize the importance of clarifying the quantitative relationship and instill the idea of clarifying the quantitative relationship into the whole process of students' decimal application problem calculation.
