【教学内容】苏教版五年级数学下册第50~51页。【教学目标】1.使学生经历探索利用规律解决复杂问题的结构化的教学过程,发现并理解和与积的奇偶性的规律。2.使学生在探索规律的过程中,经历“举出例子——观察比较——寻找特点——归纳规律”的方法结构,积累探索规律的相关经验。3.在学生经历探索规律的结构过程中,进一步培养学生合作交流的能力和学生的语言表达能力,激发学生探究数学规律的兴趣和信心,提升学生的学习
Teaching content】 【Soviet version of the fifth grade mathematics volumes 50 ~ 51 pages. Teaching Objectives 1. To enable students to explore the use of laws to solve complex problems of the structured teaching process, to find and understand and product of the law of parity. 2. To enable students to explore the law in the process, under the “cite examples - observation and comparison - to find characteristics - induction ” method structure, accumulation of relevant experience to explore the law. 3. In the course of students’ experience of exploring the law, students should further develop their ability to communicate and communicate with each other and their language skills so as to stimulate students’ interest and confidence in exploring the laws of mathematics so as to enhance students’ learning
