1、9 加几教学设计一、课题：一年级数学 9 加几二、教材简析：20 以内的进位加法是20 以内的退位减法和多位数计算的基础，对今后计算的正确和运算速度将产生直接影响，因此，20 以内的进位加法也是进一步学习数学必须掌握好的基本功之一，9 加几是这一单元的第一课时，而算法多样化是这一单元最显著的特点。三、教学目标：1、使学生在现实的情境中，自主探索9 加几的计算方法，并在不同算法的交流中，初步理解“凑十法”的计算思路，能正确的进行口算。2、使学生经历计算方法的探索过程，获得一些数学活动的经验，培养初步的观察、操作、分析和比较能力，逐步学会有条理的思考和表达。3、使学生在参与数学活动的过程中，逐步养

2、成独立思考的习惯，获得一些成功的体验，培养对数学学习的兴趣。四、教学重点：初步理解“凑十法”的计算思路，能正确的进行9加几口算。四、教学难点：学会有条理的思考和表达“凑十法”的计算思路。五、设计理念：9 加几是在掌握了20 以内数的认识及10 加几的基础上进行教学，我通过猜一猜说一说，借助学生喜闻乐见的动物形象导入新课，让学生摆学具、互相交流等方法，初步感知 9 加几的加法，启发学生将 9 加几转化为 10 加几，充分体现学生的主观能动性。巩固练习时让学生多说、多想，运用“凑十法”，正确计算 9 加几的进位加法。六、教学过程:（一）、情境导入：1、师：小朋友们，今天小猴聪聪想和我们一起上节数学

3、课，你们愿意吗？（生：愿意。）10 加几的口算卡片2、师：下面我们做个游戏：5 秒竞猜。（师依次出示课件图1、2、3）问：“你能很快数出有多少个？”（生答）师追问：“你是怎样一眼看出有多少个的？”（生答后师重点小结图3：散乱的图形要想一眼看出有多少个，可以先数出 10 个后圈一圈，圈里是10 个，圈外有几个合起来就是十几。）（二）、导入例题：1、师：同学们真聪明，小猴想邀请大家去它家做客，看（出示例题图）它拿出最爱吃的桃子来招待大家了。观察图，从图中你知道了什么？（生：盒子里面有9 个桃子，盒子外面有4 个）2、师：茄子老师想知道这儿一共有多少个桃子，怎样列式呢？（生：9+4）。师追问：9 表
