随着社会的迅猛发展和知识更新速度的不断加快,迫使课堂教学不断改革,对小学数学课堂教学的要求越来越高。将课堂还给学生,充分发挥学生学习的积极性,这是新课改的重要一环。《小学数学新课程标准》指出:“动手实践、自主探究、合作交流”是学习数学的重要方式。通过经历大量的数学探究活动,逐步培养学生的数学意识、数学思想、独立获得和运用数学知识 With the rapid development of society and the accelerating rate of knowledge updating, the continuous reform of classroom teaching has been forced, and the requirements of mathematics classroom teaching in primary schools have become higher and higher. Returning the classroom to students and giving full play to students’ enthusiasm for learning is an important part of the new curriculum reform. The “New Curriculum Standard for Primary Mathematics” states: “Hands-on practice, self-exploration, cooperation and exchange” is an important way to learn mathematics.
