unit3教学设计

Module 1 Using my five sensesUnit 3 Look and seePeriod 1教学目标：1. 能听说、认读rise, high, go down, again, sky; 能听、说、读、写单词shadow, noon, evening, night, moon; 能听懂、读懂一天中太阳及影子变化的短文，并能用一般现在时的动词第三人称单数正确描述太阳和影子在一天中的变化。2. 借助科学实验“太阳与影子”， 通过观察和谈论太阳与影子的关系等活动来学习核心单词，运用核心句型描述一天中太阳升起和落下过程中影子的变化。3. 了解影子的广泛应用，养成仔细观察自然现象的习惯。知识结构图：Task: Learners use the simple present tense to express simple truths.Key patterns: The sun rises in the morning.Key words: rise, high, go down, again, sky; shadow, noon, evening, night, moon.Pronunciation: oo /u:/ e.g. moon noon room cool oo /u/ e.g. look book cook goodGrammar: 一般现在时及动词第三人称单数的了解及应用。教学重难点：重点：1. 学会观察和描述太阳在一天中的运动。2. 学会观察和描述一天中影子的变化。难点：1. 一般现在时中动词第三人称单数的发音和用法，如rises, goes等。 2. 学生理解课文核心知识的含义。学情分析：四年级的学生还没有学习到科学课“太阳与影子”，对于影子的形成条件还不是很清楚，但在日常生活中对太阳的运动及影子的变化有一定了解。同时，学生已经接触过很多一般现在时的句子了，对这个时态并不陌生。教学用具准备：Torches, Tools ( made by students), CAI, Flashcards, a tape.板书设计：Unit 3 Look and seetimesunshadowIn the morningriseslongAt noonhighshortIn the eveninggoes downlong教学流程： I.
