设计理念:让学生积极探索数学知识、引导学生积极的思考、培养学生综合的能力是小学数学教师引导学生学习数学的关键。教学目标:《比较分数大小》是教师引导学生认识数字概念的重要课程之一,学生如果能够深入的学习这一课的知识,以后学生就能了解到用怎样的方法比较数字的大小、懂得数形结合的基本概念、会用分数的方法解学实际的问题。在这节课的教学中,小学数学教师要让学生用探索的方法让学生自己总结概 Design philosophy: Let students actively explore mathematical knowledge, guide students to think actively, and develop students’ comprehensive ability is the key to primary school mathematics teachers to guide students to learn mathematics. Teaching Objectives: “Compare the score size” is one of the important courses that teachers guide students to recognize the concept of numbers. If students can learn the knowledge of this course in depth, students will know how to compare the numbers and know the numbers The basic concept of combining, will use the fractional method to solve practical problems. In the teaching of this lesson, primary school mathematics teachers should let students use the method of exploration to let students summarize
