1教学思路设计1.1教学内容和内容解析1.1.1教学内容:人教版《义务教育教科书·数学》七年级下册第九章“不等式与不等式组”第二节的内容:一元一次不等式。一元一次不等式包含3个课时,第1课时讲的是“一元一次不等式”的定义和解法,在后面的2课时主要讲“一元一次不等式”的应用。本节课上的是一元一次不等式的第1课时——定义和解法。1.1.2内容解析:一元一次不等式是在学习完不等式的定 1 teaching ideas design 1.1 teaching content and content analysis 1.1.1 teaching content: People’s Education Edition “compulsory education textbooks · Mathematics” seventh grade ninth chapter “the inequality and inequality group ” the second section: one dollar inequality . A one-time inequality contains three hours, the first one is about the definition and solution of “one dollar once inequality ”, and the latter two lectures mainly focus on the application of “one dollar once inequality ”. This lesson is a one-time one-time inequality class 1 - the definition of solution. 1.1.2 Content Analysis: Unary inequality is inequality after learning set
