简算,指的是灵活合理地运用数学方法使复杂的式子变得容易计算,通过简化计算方法与提高计算速度,最终达到提高解题正确率的目的。在教学过程中,我们一方面要教授学生简算的方法,教会他们如何探寻解题的最优途径;另一方面,在学生掌握技巧的过程中,我们更要注重对学生简算意识的培养,鼓励学生不应只满足于解出正确答案,还要树立勇于探索解题最优方法的意识,培养学生的创新思维。简算
Simple calculation refers to the flexible and reasonable use of mathematical methods to make complex formulas easy to calculate. By simplifying the calculation method and increasing the calculation speed, the ultimate aim of improving the correctness of the problem solving is finally achieved. In the process of teaching, we should teach students simple methods to teach them how to find the best way to solve problems. On the other hand, we should pay more attention to cultivating students’ simple-mindedness Encourage students should not only be content to solve the correct answer, but also establish the courage to explore the best way to solve the problem of awareness and cultivate students’ innovative thinking.
