1内容与内容解析本节课是《普通初中课程标准实验教科书数学》人教版第二章“整式的加减”内容中课后的数学活动.主要内容是整式知识的运用.作为“整式的加减”一章的数学活动,主要是在学生学习了整式、合并同类项的基础上,从学生熟悉的拼摆图形和日历入手,启发他们从多个角度进行考虑,用语言、符号等多种形式来表示规律,进一步用整式表示数量关系,培养学生的应用意识和创新精神.这节课主要是训练学生的观察、猜想、归纳、概括的能力,两个活动体现了变化与对应的关系,学好本节
1 content and content analysis This lesson is “ordinary junior high school curriculum standard experimental textbook mathematics” PEP 2. Chapter “integral addition and subtraction ” content after class math activities.The main content is the use of the whole knowledge as a Mathematical activities in the chapter “Integrative Addition and Subtraction” are mainly based on the students ’learning of the whole style and the merging of similar items. They start with the students’ familiar puzzle drawings and calendars, inspire them to think from multiple angles, , Symbols and other forms to express the law, and further use of the whole relationship between the number of expression, to develop students ’sense of application and innovation.This class is mainly to train students’ observation, conjecture, induction, summary ability, two activities reflect changes With the corresponding relationship, learn this section
