人教版九上数学全套课件教案整理好了📚

九上数学一元二次方程这块，整理了一份人教版的资料合集📚

文件夹分得挺细，课件教案导学案分层作业都归好类了，第1套还在更新中，第3套课件也在陆续补充，习题试卷单独放了一个文件夹方便找。

导学案是按小节拆开的，25.1一元二次方程、25.2直接开平方法、配方法、公式法、因式分解法，一直到根与系数的关系，每份都带答案，做完能直接对照。

课件PPT打开看了下，25.2.1配方法这节从知识回顾开平方根性质开始，到探究点1理解基本思想、探究点2分情况讨论方程根的个数，逻辑挺顺的，配了不少小插画不会太枯燥👀
教学设计那份文档写得比较详细，教学内容解析、目标解析、学情分析都分块列出来了，备课用起来能省不少事✏️
