《数学课程标准》中指出:“在数学教学中要充分考虑信息技术对数学学习内容和方式的影响,开发并向学生提供丰富的学习资源,把现代信息技术作为学生学习数学和解决问题的有力工具。”其中“解决问题”在小学数学教学中既是知识的重点,也是难点。而这部分知识对学生而言,较为抽象,难于理解。我们的教学就应该把抽象的事物直观化,帮助学生理解,注重学生思维能力的发展。而信息技术能
The standard of mathematics curriculum states: “In mathematics teaching, we should give full consideration to the influence of information technology on the content and manner of mathematics learning, develop and provide rich learning resources to students, use modern information technology as students to learn mathematics and solve problems Powerful tool. ”“ Where ”solve the problem " in primary school mathematics teaching is not only the focus of knowledge, but also difficult. This part of the knowledge of the students, more abstract, difficult to understand. Our teaching should visualize the abstract things to help students understand and pay attention to the development of students’ thinking ability. And information technology can
