人教版九年级上册数学课件教案全套整理

人教版九年级上册数学课件教案全套整理📚

九年级数学上册的资料翻出来整理了一下，一元二次方程这块内容真的挺多的📚

目录列得很清楚，课件加教案加导学案加分层作业，一套一套按章节排下来，25.1到25.2.4都有对应的导学案和练题型，看着就很有条理。

课件PPT那几页截图放的是公式法推导的部分，从配方法引入到判别式Δ=b²-4ac，再到三种解的情况分类讨论，步骤展示得挺细。

教案那本厚厚的，公式法这一节单独拿出来写了教学分析、目标解析、学情分析，一页页翻下来能看到备课的思路是怎么一步步铺开的。

整理这种系统性的资料确实费时间，但排好类目之后找东西方便很多🍀
