1, cultivate good habits of calculation and problem solving.

For example, it is a bad habit to standardize the format first, then not omit the steps, not make drafts at will, and not be superstitious about mental arithmetic, that is, the calculation process is completed in your mind. We should lay a solid foundation in the early stage.

2, primary school computing foundation can not be forgotten.

When I was in primary school, I learned the mixed operations of addition, subtraction, multiplication and division of integers, decimals and fractions, which directly affected the calculation ability of seventh-grade students. Generally speaking, in the seventh grade, the calculation ability is poor, and many reasons are that the primary school did not learn well. You can consciously review the calculation in primary school, especially some operation rules, to improve your calculation ability.

3. Improve students' attention to mathematical operations.

Many seventh-grade students have poor mathematical calculation ability, and they all have the bad habit of being superior to others. In the classroom, students prefer to listen to the teacher's lectures, and there are only a handful of effective time for a math class to really let themselves use their hands and brains.

In junior high school, because the teaching contents involved in calculation are only simple and difficult operations such as "addition, subtraction, multiplication and division" and the solution of unary equations, students can easily master them, and they will form the wrong idea that mathematical operations are easy to learn and will not make mistakes in their minds.

4. Cultivate students' interest in computing.

Attach importance to the teaching of operation process and guide students to think. Because junior high school mathematics knowledge is abstract, mathematical operations are more about demonstrating mathematical relations than calculating results, which increases the difficulty for students to understand. Teachers' correct guidance helps to lower the threshold of understanding.

5, pay attention to the foundation

Sometimes the problem of calculation goes far beyond carelessness. It may be that students are not clear about the elementary arithmetic rules of addition, subtraction, multiplication and division, and their memory of multiplication formulas is inaccurate, and the root causes of the problems are uneven. So first of all, we should make a comprehensive survey of students to find out what problems they have in computing, and then give targeted counseling.

In view of the fact that the foundation is not good enough and solid enough, we should find problems as soon as possible, make corresponding plans, strengthen the study and mastery of relevant basic knowledge, and gradually improve our ability and level through repeated practice and consolidation. On the way, under the guidance of our children's teachers, their grades gradually improved and their basic knowledge became more and more solid.

6. Cultivate good study habits

Some students look around and are half-hearted in the process of writing their homework. They don't have a correct attitude towards learning, and they procrastinate when doing their homework, especially when they can't treat the calculation correctly. They thought the calculation problem was very simple, so they wrote it directly without reading it. This long-term bad study habit also leads to the poor mathematical calculation ability of seventh grade children.
