数学是一门计算量比较大的学科,但并不是所有的计算都是精细的计算,会涉及估算的内容。估算是一种数学能力的体现,是一种比较重要的思维方法。这种粗略的计算形式在实际生活中的应用也是非常广泛的,在教学过程中,教师需要进行估算意识的渗透,并且进行正确的方法指导,让学生逐渐形成一定的估算能力。在教学的过程中渗透估算的方法,让学生提升对数字的敏感度,能够有效提升学习效率,提高教学质量。一、创设教学情境,培养估算意识
Mathematics is a computationally intensive discipline, but not all calculations are elaborate calculations and involve estimates. Estimation is a manifestation of mathematical ability, is a more important way of thinking. This rough form of calculation is also widely used in real life. In the process of teaching, teachers need to carry out the estimation of the infiltration, and the correct method of instruction, so that students gradually form a certain ability to estimate. In the process of teaching, we can penetrate the method of estimation so that students can enhance their sensitivity to numbers. This can effectively improve learning efficiency and improve teaching quality. First, create a teaching situation, develop a sense of estimation
