第4单元表内乘法(一)第2小节2--6的乘法口诀【第三课时】2、3的乘法口诀一、教学内容分析:人教版《义务教育课程标准实验教科书·数学(二年级上册)》第54页的内容。
本学期学生初步接触乘法,乘法是今后学习表内除法和多位数乘、除法的基础。
为了让学生掌握好乘法,根据学生的生活经验和知识基础,教材安排了“乘法的初步认识”,接着编排了“5的乘法口诀”,这些内容为“2、3的乘法口诀”做了很好的铺垫。
把2、3的乘法口诀编排在一起,口诀内容丰富,容易激发学生的学习兴趣。
教材以生活中的乒乓拍子和气球的事例设计了2、3的乘法口诀,教材内容生动、直观,又充满学生动手、动脑、动口的实践活动,有利于激发学生学习的情趣,理解掌握数学知识,又利于促进学生多方面能力的提高。
二、学生情况分析:学生已经学习了“乘法的初步认识”的内容,从认识相同数相加开始,逐步体会了乘法运算的意义;学生在理解的基础上掌握5的乘法口诀,学生对琅琅上口“5的乘法口诀”,产生浓厚的学习兴趣,对“乘法”产生了亲切感,为学习“2、3的乘法口诀”打下了良好的基础。
由于学生思维水平的不同层次,学生对“5的乘法口诀”的理解和熟练程度有差异,而且低年级学生自控能力较差,面对新知识的挑战,教师要关注学生的个性差异,充分发挥自主探索、小组合作的作用,通过趣味性的游戏,调动学生的学习积极性,获得愉快的数学体验,让不同的学生都得到发展。
三、教学目标:1.知识与技能:使学生学会1~4的乘法口诀,理解口诀的来源,明确每句口诀的意义。
2.过程与方法:使学生熟记乘法口诀,并能利用乘法口诀正确地、比较迅速地计算。
3.情感态度与价值观:培养学生初步的观察、总结能力。
四、教学重点:理解口诀的来源,掌握推导口诀的方法。
五、教学难点:理解口诀的来源,掌握推导口诀的方法。
六、教法和学法:讨论法、小组研讨发。
七、教学具准备:游戏的图片、小棒八、教学过程一、创设情境:看看图片,这是什么?出示乒乓球拍图片二、探究新知(一)学习2的乘法口诀1.教师:同学们都特别爱打乒乓球,一副球拍有几只?说一说是几个几?请你列出乘法算式?2.教师:你能编写出相应的乘法口诀吗?2×1=2 1×2=2 一二得二(教师板书)3.教师:1副球拍有2只,2副球拍有几只?说一说是几个几?列出乘法算式?你能编写出相应的乘法口诀吗?2个2 2×2=4 二二得四(教师板书)4. 教师:2的乘法口诀有几句,分别是什么?和同桌说一说。
