课题 Unit 6 How many 单元 Unit 6 学科 English 年级 Three
教材分析 B部分共四页，分两课时。第一课时仍然呈现情景对话和练习。吴斌斌在公园里的赛车场旁写生，Am主发现了他的新彩笔，并问他有多少支。通过这个对话，展示询问别人拥有多少物品的句式：How many crayons do you have 以及回答：You have sixteen crayons. 并呈现新的三会数字词汇：sixteen。Let’s find out是个调查活动。学生制定调查表格，不断用重点句式询问自己的同学拥有的文具的数量，并将结果填入到表格中去。从而达到让学生在“用中学”的目的。第二课时通过John在赛车场询问工作人员车辆数目的对话，呈现三会数字词汇：sixteen, seventeen, eighteen, nineteen, twenty；以及重点句式：How many cars do you have We have twenty. 并通过一个Chant，来练习这些重点词汇，并在韵句进行简单加法运算的接触。之后的阅读练习、听一听判断正误、看一看选一选的练习以及歌曲都用来巩固练习本课的重点词汇及句型，与C部分合为一个课时。
