各地的教材各不相同,为学生的学和教师的教提供了丰富的、多元的教学素材。教材版本虽然不同,但教学内容大致相同,数学思想贯穿其中。为了让学生能更好的学习数学,喜欢数学,真正徜徉在美妙的数学花园,作为数学教师要根据师情、班情、生情将原有的数学知识重组、整合、拓展、并合理进行二度开发。数学知识从教材的重组、学材的开发、习材的编制三个维度,将数学的数学味、综合性、实践性得以彰显。一、把握教材的温度,教材的重组和拓展 Teaching materials vary from place to place, providing a rich and diverse teaching material for student learning and teacher teaching. Although the textbook version is different, but the teaching content is roughly the same, mathematical thought runs through them. In order to enable students to better learn math, like math, really shy in the wonderful mathematical garden, as a math teacher according to the teacher’s condition, class love, the original math knowledge restructuring, integration, expansion, and reasonable conduct two Degree development. Mathematical knowledge from the textbook reorganization, the development of learning materials, materials preparation three dimensions, the math of mathematics, comprehensive, practical to be demonstrated. First, grasp the textbook temperature, textbook restructuring and expansion
