二年级数学下册教案汇总
教学反思：1、引导学生体验抽象除法竖式的过程。学生在学习表内乘除法时，利用乘法口诀已经能够在算式上直接写出得数。教材安排了“18个苹果，每盘放6个，可以放几盘”的“分苹果”活动，列举了四种解决这一问题的方法。在此基础上，引导学生按照自己的想法来分这些苹果，进而再由对除法竖式有一定了解的学生介绍竖式计算，并且把竖式中的每一步所表示的含义和分苹果的活动紧密联系起来。2、在探究中理解除法的试商方法。学生通过实际操作、观察比较，培养学生质疑和创新精神，学会学习、积累数学活动经验的有意义的学习过程。3、不足：这节课上得不够生动、活泼。

人教版新目标初中英语八年级下册It’s a nice day, isn’t it教案2篇
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好！欢迎你！请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢？“噢，不！”与陌生人谈话太困难了。但是这也很有意思，并且你还能交到朋友。你该怎么做呢？闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员，不是吗？”“我希望自己能认识她，你呢？“今年的雨水很多，不是吗？”反意疑问句是一种礼貌用语。为了使得谈话成功，你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧，下次在英语课上，你会发现与大家展开谈话是一件很容易的事情，不信我们来试试。)

人教部编版语文八年级下册口语交际即席讲话教案
预设 示例：班上分享个人读书经验大家好！既然今天是交流读书体会，那么，我想结合自己的读书体会和大家聊聊读书。一个爱读书的民族，必定是一个文化素质较高的民族;一个爱读书的人，也必定是一个文化素质较高的人。读书能开阔我们的视野，提高我们的写作水平；读书能提升自身修养，丰富我们的人生底蕴。读书是我们精神的呼吸，能让人保持平淡的心境，变得博爱而无私。为了让我们的生活和心灵变得轻盈一些，我们需要读书。那么，应该怎样读书呢?其一，要择书而读。需要的才是最适合的，读适合的书才能有良多收获。如果没有特别需要的书要读，可以读经典。经典是经过岁月沉淀下来的人类智慧的结晶，可以让我们触摸先贤的思想，以充实自身。其二，要读而有术。要对好书反复品味，将其内化吸收，然后进行批判性阅读，有自己的思想主张和拓展探究价值判断;在读书过程中与作者进行辩论，最后形成自己的思想体系，为我所用，而不是让自己的脑袋成为别人思想的“跑马场”。
