分数应用题是小学数学教学的重要内容之一,通过复习,要让学生从分析数量关系入手,沟通知识的联系,区别知识的异同。形成完整的知识体系,并总结解题规律,提高分析问题和解决问题的能力。我在分数应用题复习中,采用了题组复习的形式,收到了好的效果。抓关键搞清基本数量关系解答分数应用题的关键是“分率”问题。先设计理解“分率”的题组,接着出现找“对应分率”的题组,
Fractional application questions are one of the most important parts in elementary mathematics teaching. Through reviewing, students should start from analyzing the relationship of quantity, communicate the connection of knowledge and distinguish the similarities and differences of knowledge. Form a complete knowledge system, sum up the law of problem solving, and improve the ability to analyze and solve problems. I applied in the score review, using the form of review group, received good results. Grasp the key to clarify the basic relationship between the number of answer questions Application of the key is the “rate” issue. First designed to understand the “fraction” of the group, followed by looking for “corresponding rate” of the group,
