Unit 1 How tall are you ? 教案及教学反思(2)

　　板书并教读单词 “sperm whale”和“killer whale”. 学生跟读并齐读数遍。

　　(2) 课件呈现两种鲸鱼的长度，教师说：“The sperm whale is 15 meters.The killer whale is 8 meters. 板书并领读 meter, teach:1meter=100cm, let the students guess the meaning of “meter” Teacher says 1 meter=100cm, 15 meters=1500cm, 8 meters=800cm.

　　(3) 课件呈现两种鲸鱼的重量，Teacher says: “The sperm whale is 35 tons. The killer whale is 3600kg.”板书并领读3600kg. Teachet says: “1000kg=1ton.”板书并教读 “ton” Let the students guess the meaning of “ton”.Teachet says: “1000kg=1ton,3600kg=3.6tons “

　　(4) 出示课件 Teachet says: “Look,they are sperm whale’s food. This is a squid, a lobster,a shark.” 板书并利用音节教读这几个单词。

　　课件呈现鱼、鸟、海豹和鲸鱼的图片.

　　Teacher says: “They are killer whale’s food. This is a seal.”板书并教读单词seal. Teacher says : “The killer whale eats fish,birds,seals and even whales.”板书并领读单词even,让学生猜测even的汉语意思意思。

　　（设计意图：本课的生词量特别大，为了解决这一问题，先是通过对两条鱼的比较，自然的引出新单词sperm whale 和killer whale ,通过联系旧知识，让学生自己猜测本课的新单词meter和ton, 然后通过图片的展示，教读本课的新单词squid, lobster, shark, seal, 最后帮助学生通过上下文来猜测单词even的意思，帮助学生扫除下一步阅读的障碍。）
