这是苏教版三年级下册的内容。这节课主要教学两步连除解决简单的实际问题,目的是让学生经历探索解决问题的全过程,提高学生解读情境、提出问题和分析解决问题的能力。在此之前,学生已经有了两步计算解决简单实际问题的经验。那么,怎样帮助学生更清晰的理解解题思路?怎样让学生学会选择有效信息,运用数学知识和方法解决问题?又怎样让学生积极主动的经历探索解决问题的全过程?……带着这样的问题开始了我的磨课之旅。【版块一】问题呈现方式第一次教学1.我们班有50位同学,刚才排队上来时老师把你们平均
This is the second edition of the Sujiao version of the content. The main lesson in this lesson is to solve two simple problems in real time. The purpose is to enable students to go through the whole process of exploring and solving problems, improving students’ ability to interpret situations, ask questions and analyze problems. Until now, students have taken two steps to calculate their experience in solving simple, practical problems. So, how to help students understand the problem-solving ideas more clearly? How to let students learn to choose effective information, using mathematical knowledge and methods to solve the problem? How to make students actively explore the problem-solving process? ... With this The problem started my study tour. [] A version of the first question mode of presentation 1. Our class has 50 students, just line up when the teacher average you
