Careful examination of questions is the premise of correct problem solving and accurate calculation. On the one hand, students' literacy and understanding level are low; On the other hand, he is eager to succeed in doing the problem and is unwilling to examine it. Therefore, parents should cooperate with teachers, guide children to understand the importance of examining questions and enhance their awareness of examining questions. At the same time, we should also teach children how to examine questions, establish basic procedures for solving problems, such as "examination-formulation-calculation-examination-answer", and put the examination first in the process of solving problems.
2. Cultivate children's habit of careful inspection.
In the process of solving problems, cultivating children's habit of careful examination is the key to ensure the correctness of solving problems. Teachers can take checking calculation as one of the basic links in the process of solving problems in teaching. Strengthen practice, strictly demand and urge students to do it, and explain to students what checking calculation is, as well as the method and significance of checking calculation. Parents can also guide their children to practice this method and form a habit when they are doing their homework.
3. Cultivate children's habit of careful estimation
Estimation is a shortcut to ensure the accuracy of calculation, but now many teachers think that estimation is rarely ignored as an examination content, which is very wrong. Teachers should seize every opportunity to consciously let students master the estimation method and guide them to discover some laws of sum, difference, product and quotient. For example, 2040÷40, when estimating, take 2040 as 2000 and 2040÷40 as 2000÷40, which can be used to check whether the highest digit of calculation is correct and let students understand the importance of estimation.
4. Cultivate the habit of children to finish their homework independently.
There are many homework in primary school math class, and some students with strong ability can do it quickly and accurately. After they finished, they couldn't wait to report the methods and results of solving the problem. This makes some students who are slow to do the questions copy their own results without thinking. After a long time, these students have developed the bad habit of being lazy to think. Therefore, cultivating children's habit of completing homework independently is the premise for him to learn mathematics well.
5. Cultivate children's habit of questioning and asking difficult questions.
Students should use their brains more and be diligent in thinking. Don't be satisfied with reciting concepts, formulas, laws, etc. , but try to understand them. Questioning and asking difficult questions is a valuable learning quality, which enables students to study hard, think hard and take the initiative. Ask questions you don't understand, don't be shy to ask questions, discuss with your classmates, and never stop until you figure out the problems. When the problem is solved, students will enjoy the joy of success and improve their interest in learning mathematics.
6. Cultivate children's habit of finding mistakes by themselves.
Students will inevitably make mistakes in their studies. In this regard, teachers cannot take it lightly. Because the place where students make mistakes is the weak point of their knowledge, and it may be typical and universal. Teachers should guide students to find their own mistakes and use the inspection methods they have learned to find them. Grasp the key to the problem in comparison, try to find and correct mistakes by yourself, and improve problem-solving skills.
