认数,是学习数学知识、解决实际问题的基础。新课标实施后,教材淡化了“形式化”的认数形式,强调通过创设情境让学生深入感受、体会,领悟数的意义,培养数感。在摒弃了以往教学仅仅是认识“数”后,如何更好地把握教材,丰富数的内涵,帮助学生更好地理解“数”呢?通过实践教学,我的体会和思考如下。一、依托生活——把握一百以内的数的概念新课标指出:“要让学生经历从日常生活中抽象出数的过程。”对于低年级学生来说,一百以内数的认、读、写并不困难,但对数的概念只有模糊的表象。只有让学生身临其境地去体验,在实际场景中收集真实的数字信息,才能真正地帮助他们把握数的概念。
Recognition, is to learn mathematical knowledge, solve practical problems. After the implementation of the new course standard, the teaching material has diluted the recognition form of “formalization”, emphasizing that by creating situations, students can deeply feel, experience and comprehend the significance of numbers and cultivate sense of number. How to better grasp the teaching materials, enrich the connotation of numbers and help students better understand the “number” after abandoning the teaching in the past just to know the “number”? Through practice teaching, my experience and thinking are as follows . First, relying on life - to grasp the concept of the number of one hundred New Curriculum pointed out: “Let students experience the abstraction of the number of daily life from the process. ” For the lower grades of students, Reading, writing is not difficult, but the concept of logarithm only vague appearance. Only by allowing students to experience the immersive experience, in the actual scene to collect real digital information, can really help them grasp the concept of numbers.
