估算是小学数学教学的重要内容之一,它不仅仅是数学考试的热点,更是“学数学、用数学”的教学重点及难点。面对小学数学估算教学中所出现的教学观念不科学、课时不保证、学生估算能力不足及估算多为了应试等问题,教师可采用创设现实情境,以此激发学生学习兴趣;有针对性、有计划地强化估算训练,并教授学生学习估算的方法;将估算例题与实际情境结合起来,强化学生的运用的方式,提高学生的估算能力,最终实现学以致用的目的。
Estimation is one of the most important parts in elementary mathematics teaching. It is not only the hot point of mathematics examination, but also the teaching focus and difficulty of “learning math and mathematics”. In the face of primary school mathematics estimation teaching appeared in the teaching concept of unscientific, class time is not guaranteed, the students lack the ability to assess and estimate more for the examination and other issues, teachers can create the actual situation, in order to stimulate students interest in learning; targeted, there are Plan to strengthen the estimation training and teaching students to assess the method of estimation; the combination of the estimated cases and the actual situation, to strengthen the way students use to improve students’ ability to estimate, and ultimately achieve the purpose of learning.
