在问赛车场的工作人员，这一过程呈现了数字单词16-20,，重点问答句已经在上一个课时对话中学习过了，在这个课时里，可以提供更多的练习机会，让学生能够做到听说、认读这一重点句式。在Let’s chant中，将两个课时的重点问答句放在了一起，同时还加入了简单的加法及乘法的表达。需要让学生运用20以内的数字进行练习，以帮助其形成英语的数字思维能力。

其次，根据计算结果来寻找16~19以内的基数词的拼读规律，进一步巩固本课时的重点单词，让学生有规律地记单词，而不是死记硬背。并引导学生从图片中获取所需信息，提升他们的听力技巧，并通过课文学习进一步巩固新知。
最后，通过学习歌谣，提升学生学习英语的兴趣，巩固本单元的重点词汇。通过游戏激发学生的学习兴趣，让学生在游戏中操练新单词，加深对新知的印象。
再通过创编对话，使学生有机会锻炼口头表达能力，同时使学生更加深刻地理解和掌握所学知识，从而更好地运用到学习、生活中。

教学反思
1.这节课是本单元的一节词汇课 在导入环节,以一个简单的猜数字游戏唤醒学生的知识储备,同时活跃课堂气氛
2.在呈现新知环节,教师充分结合学生已学知识来展开教学,以让学生回答加法算式引出新单词的教学,让学生自己寻找数字规律,这样既集中了学生的注意力,又培养了学生独立思考的能力 (共25张PPT)
