First, accurately understand and firmly grasp the concepts, properties, formulas, rules and some commonly used data required for various operations; A deep understanding of concepts, properties, formulas and rules directly affects the choice of methods and the speed of operation. Fuzzy concepts, formulas and rules will definitely affect the accuracy of operation. In order to improve the operation speed, it is still necessary to remember some commonly used data.
Two, master the general operation methods, general rules, flexible use of concepts, properties, formulas and rules for operation. Teachers can arrange and collect some flexible exercises according to the content of the textbook, cultivate students' flexibility in operation, guide students to collect, summarize and accumulate experience, form skilled skills, and improve the simplicity and rapidity of operation.
Third, pay attention to the teacher's typical demonstrations and examples in learning, and make clear the goal, calculation steps and basis of solving problems. Through typical demonstration, the transition from understanding knowledge to using knowledge is relatively smooth, thus forming operational ability.
Fourth, improve the reasoning ability in operation. The essence of mathematical operation is a process of deducing results from known data and formulas according to the definition and nature of operation, and it is also a process of reasoning. Whether the operation is correct or not depends on whether the reasoning is correct. If the reasoning is incorrect, the operation will go wrong.
Fifth, strengthen the operation practice. Any ability is formed and developed in certain practical activities. In order to effectively improve students' operational ability, we must strengthen practice, which should be purposeful, systematic and typical. By changing one question, changing one more question, solving one more question and using one more method, the proficiency, accuracy, flexibility and organization of operation are cultivated. Cultivate students' thinking depth and improve their computing ability in the form of exercise group training.
6. Get into the habit of checking calculation and master the method of checking calculation. During or at the end of the problem-solving operation, it is necessary to check the operation process and results in order to correct the mistakes in the operation process or results in time and master the checking calculation method.
