估算,是日常生活中一种常见的计算方法,许多问题有的只需要了解大致的结果,有的很难算出准确的结果,这就需要用估算的方法来帮我们解决问题。因此,在小学数学教学中,增强学生的估算意识,让小学生掌握一些简单的估算方法,对帮助学生学会运用数学的思维方式去观察、分析现实社会,去解决日常生活中的问题,从而培养他们的数感及数学应用意识都有积极的意义。
Estimation is a common calculation method in daily life. Many problems only need to know the general result, and some can hardly calculate the accurate result. Therefore, the estimation method needs to be used to help us solve the problem. Therefore, in primary school mathematics teaching, we should enhance students’ sense of estimation and help pupils master some simple estimation methods. Students should learn to apply mathematical thinking to observe and analyze the real world and solve problems in daily life so as to train them The number of sense and mathematical application of awareness have a positive meaning.
