一、背景分析在实际教学过程中,教师要借助对实际活动的讲解和分析处理,确保学生能更好的学习并了解分米和毫米,从而进一步掌握长度单位。并且,在学习过程中,也要了解长度单位之间的换算关系,从而更好地提升学生在生活实际中的估测能力,并且能提升整体动手操作和合作交流的意识,为生活学习提供便利。二、案例描述(一)设置教学目标1.本堂课教师要引导学生结合生活实际了解并认知长度单位,分块学习分米和毫米的相关知识,并且在原有学习基础
First, the background analysis In the actual teaching process, teachers should help explain and analyze the actual activities to ensure that students can better learn and understand the decimeter and millimeter, so as to further grasp the length of the unit. In addition, in the process of learning, we also need to understand the conversion between length units so as to better enhance students’ ability to estimate in real life and enhance the awareness of overall hands-on operation and cooperation and exchange for the convenience of life learning . Second, the case description (A) set teaching goals 1. The class teacher to guide students to understand the actual life and cognitive length units, block-based learning decimeter and millimeter-related knowledge, and based on the original learning
