数轴是数与图形和谐结合的完美桥梁,数轴和数轴思想在数学研究中有着非常重要的作用.数轴和数轴思想一直伴随着我们的数学学习和研究.在义务教育学段,数轴和学生的数学学习形影不离.同时,它也为后续的平面直角坐标系和空间坐标系等知识的学习起到了铺垫的作用.因此,学好数轴相关知识和数轴思想对学生数学能力的发展是非常重要的.以下是笔者在苏科版七年级上册数轴第1课时教学中的一些设计和感悟.
The number axis is the perfect bridge for the harmonious combination of numbers and figures. The idea of number axis and number axis plays a very important role in the study of mathematics. The idea of number axis and number axis has been accompanied by our mathematics study and study. In the compulsory education section, It also paved the way for the subsequent learning of planar Cartesian coordinate system and spatial coordinate system, etc. Therefore, it is very important for students to learn mathematics ability to learn several axes of knowledge and axiom. The author in the Su Ke version of the seventh grade number of the first axis when teaching some of the design and perception.
