学习好资料欢迎下载小熊请客说课稿李美荣一、教材分析小熊请客 选自北师大出版社二年上册第二单元乘法口诀(一)的第六课时.4 的乘法口诀。他是在学生学习了、的乘法口诀的基础上进行教学的，教材在这里用“小熊串红果串请客”这一情境入手，引导学生自觉经历用连加的过程，为编的口诀做准备。在推导的乘法口诀时，采用实践探索法，让学生感知知识的形成过程，让学生学得有亲切感。在交流总结时，引导学生总结出口决特点。根据本册教材的编写意图和特色，确立本节课的教学目标为：知识目标：、让学生利用的连加和已学过的乘法口诀得出，经历的乘法口诀的编制过程，理解和掌握的乘法口诀，并理解每句口诀的含义。、能运用所学口诀，完成表内乘法的计算，并解决生活中的实际问题。能力目标：引导学生探索规律，初步培养学生分析、综合能力；提高学生的计算能力。情感目标：、在数学游戏中让学生体会数学存在于生活中，从而强化学习好资料欢迎下载学习数学的兴趣。2、“乘法口诀”他是中华文明的一个瑰宝，可以说是中华民族聪明才智的结晶，他可以培养学生爱国之心及自豪感。二、说教法、学法根据教学内容特点和学生的认识规律，创设“小熊请客”的情境，通过观察发现信息，表达信息，并借助乘法意义编制口诀，而且通过“开火车”和“对口令”等多种形式，观察学生记忆口诀的流畅性和了解口诀记忆的准确程度。同时在教学中，注意独立思考，小组交流的学习形式的交互运用，达到发展智力，培养学生有条理地思考问题的习惯和初步的推力能力的目标。教学准备：小熊玩具、“小熊请客”主题图，试题卡、幻灯片、气球三、教学过程（一）创设情境我首先拿一只玩具小熊让大家猜，并用小熊过生日用红果招待朋友的故事情境导入,使学生一开始就有快乐的心情步入课堂，然后我用大屏幕出示主题图，主题图色彩鲜明，一定会让学生们兴趣盎然，并在以往的基础上，他们会很快去找主题图上的数学信息，并展示给同学们。他们肯定会说：小熊串的红果串，每串个，他已经穿了串，他还要串也一定是个个串的，当然在这里也有可能有的同学会把老师刚才所说的小熊过生日用红果招待朋友，小熊自己在家里串红果串等等，说得很完整，文档编码:CJ10Z5S7A9K8

页下面的数学游戏，可以这样进入。比赛结束，大家玩得正起劲，忽然发现主人公小熊不见了，只看见桌子上留了纸条，上面写道：走过迷宫，你就能找到我，我们就能一起吃上酸甜可口的红果串了。快来吧！这也正照应了开头小熊用红果串请客的主题。我感觉我这样设计特别吸引学生的好奇心，恨不得马上去参加这种学习活动，这正符合在玩中学、在学中玩的新课程理念。充分调动了学生的学习积极性，把枯燥的知识有声有色的注入学生心田，极大地提高学生学习数学的兴趣，增强学习数学的自信心。最后提到的红果串其实也是一个小埋伏，这里边有思考题，那就看时间而定了，文档编码:CJ10Z5S7A9K8
