数感是数学核心素养之一,培养和发展学生的数感既是数学教学的重要目标,也是课标理念能否真正落实到教学实践的重要体现。那么在数学教学中,应如何有效地培养学生的数感,不断提高学生的数学素养呢?一、加强体验培养数感“常见的量”总复习教学片断,我出示:“小亮日记”:小亮日记2009年2月29日星期一今天天气特别好,早晨17点不到我就从我那长20厘米、宽12厘米的小床上爬起来,拿起我那17米、重25千克的牙刷,不到两小时我就洗刷完毕,抓起妈妈特意为我准备的大约1平方米的烧饼,
Sense of number is one of the core qualities of mathematics. Developing and developing students’ sense of number is not only an important goal of mathematics teaching, but also an important manifestation of whether the concept of lectures can really be implemented in teaching practice. So in mathematics teaching, how to effectively develop the sense of number of students, and constantly improve their mathematical literacy? First, to enhance the experience of training a sense of “common amount” total review teaching pieces, I show: “ Diary ”: small bright diary Monday, February 29, 2009 Today the weather is particularly good, less than 17 in the morning I from my 20 cm long, 12 cm wide crib up, picked up my 17 meters, Weight 25 kg toothbrush, less than two hours I wash finished, grabbed my mother prepared for me about 1 square meters of sesame seed cake,
