以唱歌的形式创造轻松的学习氛围并复习数字1-20。

检查学生前一天在平板上完成的拼写数字单词的作业，在分析和总结的过程中引导学生认识“right” 和“wrong”。在奖励得了一百分的孩子时教授单词one hundred既让学生在真实情境中学习新单词，同时又自然的交代了本节课的评价方式.

一开始就交代评价方式：努力学习获得积分卡，最后小组一起用得到的积分卡兑换自己想要的礼物。且以积分兑换自己喜欢的礼物而完成一个又一个的任务贯穿整节课，让学生始终在创设的情境中学习。

通过出示积分可以兑换的奖品，既提高学生的学习积极性，又复习了数字，且自然的过渡到本节课的新知识100以内的数字。

让学生自己发现并总结整十数字的特点，学生能比较容易的记忆并拼写出单词。

小组活动：一共有五个不同的任务，每个任务有不同的分值，(Task 1: count numbers from 55-67<22points>; task2:count number from 25 to 80, like 5,10,15..<28points>）由小组长用优学派抽取任务，再一组一组展示他们的任务，其他小组认真听并用 “right” or  “wrong”及时给予评价。小组合作完成任务既训练了他们的团队合作精神，又让每个学生都能参与到课堂中来,并操练了“right” “wrong”。

用神秘礼物再次激发学生的兴趣，既训练了学生口语，复习巩固了数字，又培养了学生认真倾听的习惯。

让学生们自己加自己小组的积分，在这个过程中既训练了学生说数字，又自然的引入和操练了句型__and __is__,且让学生们饶有成就感，激发了学生接下来的学习积极性。

利用优学派互动题板，让学生听音选填数字，（听音选择四个单词，另外四个单词由学生动脑筋填写与同一线上单词相加等于100 的数字），既让每个学生都训练了听力，又训练了学生思维能力。

Step 4: Consolidation and sum up

1. Design a piece of homework.

  Show an example:

2. Let the Ss exchange their homework and add the numbers.

3. Let the Ss check the answers in groups.

4.Redeem the gifts with the points.

5. Sum up.

  No pains , No gains.

 Study hard !You’ll get one hundred.

6.Homework: Finish the dictation on the tablet.

1.   Design a piece of homework on their paper.

2.       Change the homework and add the numbers.

3.Check the answers in groups.

4.Discuss in groups:

  Ss count and add their points in their groups , then discuss what do they want.

 Tips:

__and__and__is__.

 What do you want?

   I / We  want....

5.Listen to teacher carefully.

让学生自己设计一份一百以内的加法题，训练了学生写英文数字，练习了本单元的重点句型，巩固了学生写英文句子需要注意的要素。

让学生相互交换自己设计的作业，检查出题人的书写是否正确和规范，然后算出答案，学生在这个相互检查的过程中再次巩固了本节课的新单词和句型，也让学生养成良好的检查的习惯。

最后一个环节让学生算出本小组得到的积分总数，并讨论大家想兑换和能够兑换的奖品，在这个过程中，学生既体验了  “一分耕耘一份收获”和团队合作的成就感，又训练了学生的综合语言运用能力。
