2、境，导入复习。上一节课我们复习了10 以内数的认识和加减法，大家了解了哪些知识？谁愿意来说一说？（根据学生说的情况，有选择地板书）。关于 10 以内数的认识和加减法的内容真不少，这节课我们把复习的内容练习一下，看一看小朋友们掌握得怎么样！板书：整理和复习（二）二、重点复习，强化提高。1复习 10 以内数的认识。（1）报数游戏。老师发现小朋友们一个小秘密，你们想知道是什么秘密吗？（想）老师发现小朋友们都特别喜欢上体育课，喜有关连加、连减、加减混合的题目，应说一说先算什么，再算什么？vip 会员免费欢体育活动。上体育课就要站队，老师想看一看你们队站的好不好？老师选10 名小朋友到前面来，按高矮站成

3、一排。（选 10 名学生到前面站队）小朋友们体育课上得不错，队站得又快又整齐,下面我们来报数。排头的小朋友报“1”，第 2 个小朋友报“2”，接下来依次朝后报数。开始！（报数开始）。看到这些小朋友站得这么整齐，你知道他们各排在第几吗？（找几名学生回答。）参加报数的小朋友一共有多少人？(10 人)最后一位小朋友排第几？（第10）。这两个“10”的意义一样吗？（先同位交流，再全班交流。）（2）有一群小动物确不是这么报数的，看它们来了，它们是怎么报数的呢？（出示第6 题）仔细观察这两队的小动物报数有什么特点呢？引导学生思考：第一队的小动物报数是第次要加2，而第二队的小动物报数是每一次都减2。（3）手

4、势表演。老师还知道小朋友们不但喜欢体育，还喜欢表演。现在我们分组用手势表演数的组成，看哪一组表演得最好！一排为一组，正好 8 组。第 1 组的小朋友表演2、3 的组成，其他组依次表演一个数的组成就行。（学生表演后师评价。）（4）根据数的组成写算式。小朋友们表演的真好！你们还能用数的组成写算式吗？指导生在教材上独立解决练习十六第1 题。2.看图列式的练习。看到小朋友们表演的这么好，小白鸽也飞来凑热闹了。瞧！他们站在草地上正朝我们这里看呢。（投影出示练习十三的第 2 题。）你能根据这幅美丽的图，写出两道加法算式和两道减法算式吗？先让学生独立完成，然后交流。交流的重点是一图四式，并理解加法算式和减法

5、算式之间的联系。3“用数学”的练习。(1)小朋友们学习这么认真，不但吸引来了蜻蜓，还把小蜗牛也吸引来了，看！（投影出示练习十六第3 题）仔细观察图，你能解决图中的问题吗？图中的问号表示什么？先让学生独立完成，然后组织交流，重点交流说图意、列式。(2)出示练习十六第5 题（1）图今天真是太热闹了，连梅花鹿也从很远的森林跑来了，看把梅花鹿渴的，一口气喝了三瓶饮料。从图中你能知道哪些数学信息呢？根据数学信息你能提出什么问题呢？注意引导学生发现信息，引导学生观察每两个数，找出两个数相差几文档编码:CY5O6Y6T9B2 HL10N10C4S10E2 ZO8I3W5J5L3文档编码:CY5O6Y6T9B

13、图意，并找到要解决的问题。4计算的练习。练习十六的第3、5 题。下面我们要做个游戏：抢答老师出示一张口算卡片，谁第一个想到得数，站起来就说，好吗？师出示卡片，生抢答。并及时让学生说一说：你是怎样算的？5练习十六第7 题：填数，使每条线上的三个数相加都得 10。首先，让学生理解“使每条线上的三个数相加都得10”这句。同时让学生指一指哪三个数得10？其次，引导学生观察我们应该先填哪条线上的数呢？必须要知道几个数？（两个）所以可先填左斜和横线。最后，引导学生思考应填几？如：横线上一个是3 一个是 2，怎么办？要让学生知道，先把3 和 2 合起来是5，再想 5 和几组成10？6、古代小知识请小朋友们仔

14、细看，你知道些什么？与现代的数学相比，你认为哪种表示方式好？好在哪里？引导学生将古今数学进行相比，让学生发现现代的数学更简洁。三、自主检测，完善提高。1自主检测。通过今天的复习，相信小朋友们对10 以内加减法的计算有了更大的提高，让我们来检测一下吧！（限时 5 分钟）。(1)口算。3+2=2+7=10-9=7-4=8-4=6+4=5+5=1+8=9-4=4-4=10-7=3+6=8+2=1+9=7+3=3+3+2=7+2-5=9-7-2=10-6+5=（2）画，和同样多。文档编码:CY5O6Y6T9B2 HL10N10C4S10E2 ZO8I3W5J5L3文档编码:CY5O6Y6T9B2 HL
