1、1120 各数的认识教学设计【教学内容】人教版小学数学一年级上册7374 页。【教材分析】1120各数是帮助学生建立数位概念的重要知识点之一,学生对数的认识不仅仅是单独的一个个数,而是以十个为一体进行数数,这是建立十进制数位概念的重要阶段。教材中所呈现的内容分为两个部分:一是数一数,摆一摆,这是运用学生原有的经验,建立十个一捆的观念,进而帮助学生建立1120 各数的表象;摆一摆,想一想,这部分内容的侧重点是把图像与数结合起来,这也是学生过渡到抽象符号的重要环节。同时,学习本部分的内容,让学生知道十几的数分别是由 1 个十和几个一组合成的。二是数的认识的拓展。为了让学生较全面认识数,教材安排了在
2、直尺上读数。【学情分析】1020各数学生能数出来,但是对于它们的组成不了解。还有就是 10 根捆成一捆的简便性更是一片空白,怎样能让学生感知10 个的数的简便性,是本节课的重点,让学生通过操作活动来理解和建立数位的概念,但是一年级学生自我约束能力差,注意力易分散,怎样实效地组织活动也是本节课所要考虑的重点。【教学目标】1、创设教学情境,让学生主动参与活动过程,初步认识1120 的各数,知道这些数是由1 个十和几个一组成的。掌握20 以内数的顺序、大小。2、经历观察、操作、思考等数学活动,培养学生的思维能力。3、培养学生积极参与生动、有趣的数学活动,激发学生对数学的好奇心和兴趣。【教学重点、难点
