【教学设想】本节课力求在以下三个方面有所突破:一是精心组织材料。围绕找规律的“找”字组织材料,环环相扣,逐层深入。二是提供探究空间。规律的得来不是一蹴而就的,而应是学生在大量感知、丰富积累后逐步归纳的过程。教学预设了以下线索:直观的动手操作一丰富的表象思考一简约的列式计算一抽象的数学模型,每一层次的探究活动,都给学生提供足够的探究时空,引导学生在理解中概括,在比较中抽象,在体验中感悟,使学生在“找”规律的过程中掌握科学研究的方法,深化思维。三是渗透思想方法。数学思想方
Teaching Imagination This lesson seeks to make breakthroughs in the following three areas: First, to organize materials carefully. Around to find the law “find ” word organization materials, interlocking, layer by layer. The second is to provide space for inquiry. The law is not come from time to time, but should be a large number of students in the sense of enrichment and gradually summed up the process. Teaching presupposes the following clues: Intuitive hands-on operation A rich representation of thinking A simple column calculation A mathematical model of abstraction, each level of inquiry activities, to provide students with enough space to explore, to guide students in the understanding of generalization , Abstraction in comparison, sentiment in experience, make students master the method of scientific research and deepen their thinking in the process of “finding ”. Third, infiltration of ideas and methods. Mathematical thinking square
