估算是计算教学中必不可少的重要内容,也是小学生应该形成的一项重要的数学技能。新教材加大了估算教学的力度,将估算教学内容从计算教学中分离出来,改为解决问题教学的内容之一,将估算作为解决问题的策略进行教学,体现了估算最主要的作用。在教学中,如何培养学生的估算意识,提高估算能力,让学生掌握估算的方法和策略,运用估算来解决问题,我认为要注意以下几点。一、培养估算意识,体会学习估算的必要性 Estimation is an indispensable part in teaching calculation and an important mathematical skill that pupils should form. The new textbook has strengthened the estimation teaching, separated the teaching content from the calculation teaching, and changed one of the contents of the problem teaching instead of teaching the estimation as the strategy of solving the problem, which reflects the most important role of estimation. In teaching, how to cultivate students’ awareness of estimation, improve estimation ability, let students master estimation methods and strategies, and use estimation to solve the problem. I think we should pay attention to the following points. First, to develop a sense of estimation, the need to learn to estimate
