提高数学教学质量,最基本的就是抓好备课、上课、练习、辅导、考核这五个环节。而分层教学法就要在这五个环节中起指导作用。一、备课中要分层思考数学是一门逻辑性、抽象性、应用性很强的学科。重视和加强备课工作,最重要的是认真钻研教材,正确理解教材编写意图,把握每一节新课内容的知识结构特点,掌握教材的重点和教学上的难点和关键,在新旧知识连接点上能够沟通各部分内容纵横两方面联系和思维坡度适宜的问题。对学生的的理解知识过程中可能出现的问题预作考虑,而不是孤立地去钻研教材。例如第六册“除数是两位数的除法”是在学生掌握“除数 Improve the quality of mathematics teaching, the most basic is to do a good lesson preparation, class, practice, counseling, assessment of these five areas. The hierarchical teaching method will play a guiding role in these five aspects. First, to prepare lessons in a hierarchical way Mathematics is a logical, abstract, highly applied subject. Emphasize and strengthen the lesson preparation work, the most important thing is to carefully study textbooks, a correct understanding of the textbook intent, grasp the knowledge structure of each section of the new lesson content, grasp the key teaching materials and teaching difficulties and key points in the new and old knowledge Able to communicate aspects of the contents of all aspects of vertical and horizontal connections and thinking appropriate slope problem. Instead of studying textbooks in isolation, you may want to think about possible problems that may arise in students' understanding of knowledge. For example, the sixth book “Divisor is a two-digit division” is the student masters "divisor
