所谓数感,主要是指涉及到数量关系方面的感悟。帮助小学生建立数感,不仅有助于提高学生数学思维能力,还能帮助学生理解生活中数的意义。笔者以四年级上册“认数”教学为例,谈谈在课堂教学中如何培养学生的数感。一、通过观察养成数感对数的读写是培养学生数感的重要途径。在教学过程中,教师如果不重视学生对数的观察,急于引导学生读写数,就必然导致学生对数停留在被动接受,自然也失去了对学生数学思维的培养。所以,教师在教学过
The so-called sense of number, mainly refers to the number of relations related to sentiment. Helping pupils build sense of numbers not only helps to improve students’ ability to math thinking, but also helps students understand the meaning of number in life. The author of the fourth grade on the book “recognition ” teaching, for example, talk about how to cultivate students in classroom teaching sense.

So, teachers are teaching
