1、10 的加减法教学设计【教学内容】义务教育课程标准实验教材小学数学第一册第61 页【设计理念】在生活中，学生大部分已经掌握了10 的组成，因此在教学中我从他们自身的知识背景出发，进行教学活动。课堂体现生活化、活动化、自主化、情感化和趣味化使他们体会到数学就在身边生活中处处有数学，并根据低年级儿童喜欢活动和游戏的特点，我设计了生动活泼的练习，让学生在游戏中亲身体验知识的形成与发展。从中获得成功的喜悦，提高学习的兴趣。【教材分析】教材采取的是让学生对照点子图直接利用10 的组成进行计算，并且呈现的形式是先让学生根据算式写答案，逐步过度到让学生自己根据点子图去填，最后取消点子图。10 的加减法是在学
2、生已经比较熟练地掌握10 的组成，并且通过一图四式的练习，初步认识了加减法的含义和加减法算式之间的联系的基础上进行教学的。10 的加减法是以后学习20 以内进位加和退位减的重要基础，因此应该重视学生已有的基础，在自主参与、主动探究中引导学生建构知识，帮助他们自主探索出10 的加减法的所有算式。【学生分析】学生在学习本课之前已经比较熟练地掌握了10 的组成，并初步认识了加减法的含义，以及加减法算式之间的联系，为学习 10 的加减法作了知识化的铺垫。10 的加减法是以后学习20 以内进位加和退位减的重要基础，它是本单元中最重要的教学内容。一年级学生刚入学，年龄比较小，注意力容易分散，因此整节课我以
3、唱儿歌的形式贯穿始终，以此激发学生的学习兴趣和欲望。学习10 的加减法之前已经有 7、8、9 加减法的铺垫，所以学生对这一类型的加减法比较熟悉，也有一定的计算能力和计算方法（而且有很多学生在学前班和家里也已学会），所以学生学习起来就比较熟练。【教学目标】1、使学生初步学会得数是10 的加法和 10 减几的减法，并能正确口算。2、通过一图四式的教学，进一步培养学生的观察能力和口头表达能力，发展学生的思维。3、在活动中培养学生自学能力和对学习数学的兴趣和信心。【教材展现】【重点难点】教学重点：让学生通过观察，自主探索10 的加减法的所有算式。突破方法：通过创设情境，激发学生主动探索的激情，鼓励学生

34、式为什么只能列出两道列式：5+5=10 10-5=5设计意图：通过点子图，让学生独立观察，然后在交流汇报中得到全部算式，学生在自主探索和小组合作的活动中获得成功的喜悦。三游戏引入，巩固提高1游戏 找朋友（P66做一做1）用数字卡片组成 10，让学生戴好准备好的数字头饰，如果拿出卡片3，问：“谁是我的好朋友”另一生就拿出卡片7 说：“我是你的好朋友。”设计意图：本环节利用学生对游戏极大的兴趣，通过小组的交流合作，既让学生强化 10 的加减法，又学会如何与人交往。2游戏 玩扑克（P66做一做 2）老师手上拿着一张10 的扑克，然后把 19 的扑克牌发给学生。游戏规则：要求学生说出10 减自己手上的
35、扑克牌上的数字等于多少看谁说得最快设计意图：将书上单调的练习题转化成小朋友喜欢的扑克游戏，提高学生的学习兴趣。3算一算、比一比（1）孔雀身上还有许多问题呢！（课件出示图，也就是书本练习十九第6题。）文档编码:CJ6Z7H7L2M1 HE10A4F8S9W5 ZI3P7Z8I10S1文档编码:CJ6Z7H7L2M1 HE10A4F8S9W5 ZI3P7Z8I10S1文档编码:CJ6Z7H7L2M1 HE10A4F8S9W5 ZI3P7Z8I10S1文档编码:CJ6Z7H7L2M1 HE10A4F8S9W5 ZI3P7Z8I10S1文档编码:CJ6Z7H7L2M1 HE10A4F8S9W5 ZI3
