估算是我们在现实生活中经常运用到的数学计算方法,它不要求计算出准确的结果,只需要一个大致结果。但是在目前小学生数学教学中,老师不注重对学生估算意识的培养,造成学生估算能力较弱,估算方法在生活中得不到运用。随着基础教育改革不断深入,教育理念是将数学应用到生活中去,提高学生运用数学解决实际问题的能力。老师应该意识到估算的重要意义,并且设计合适的教学方案来培养学生的估算意识。
Estimation is a mathematical method that we often use in real life. It does not require calculating the accurate result, only a rough result. However, in the current mathematics teaching for primary school students, the teachers do not pay attention to the training of students ’estimation consciousness, which results in the weak ability of students’ estimation and the estimation method can not be used in life. With the continuous deepening of basic education reform, the educational philosophy is to apply mathematics to life and enhance students’ abilities to use mathematics to solve practical problems. The teacher should be aware of the significance of the estimate and design a suitable teaching plan to develop a student’s sense of estimation.
