Lesson 4 Welcome to the dog show 教案

Unit 3 Lesson 4 Welcome to the dog show
教案
1教学目标
一、学生能够对1至100的数字发音有更深刻的印象,明白其中的发音规律。
二、学生能够区别plus与minus的发音和意思。
三、学生能够对相关的问题作出回答。
四、学生能够掌握加、减等式的句型表达。
2学情分析
本课主要涉及加减法的表达,对于四年级学生而言,1到100的词汇虽然是旧知,但到目前为止并不能完全掌握,所以仍需要加强数字的复习。又由于大多数学生注意力仍不稳定、不持久,难于长时间注意同一件事物,容易为一些新奇的事物所吸引,所以本课加入情景,整个课堂为一个dog show,学生与老师共同扮演,增加课堂的趣味性。在记忆方面,这个阶段儿童思维发展开始从具体形象思维向抽象逻辑思维过渡,因此可以通过词句的反复训练和感知来习得语言。21教育网21cnjy.com
