《数学课程标准》提出:数学教学是数学活动的教学,数学活动是学生经历数学化过程的活动,是学生自己构建知识的活动,这充分表明学生应该是数学学习的主人。教师在教学中要紧密联系学生的实际,从学生的生活经验和已有知识体验出发,创设生动有趣的情境,让学生亲近数学;引导学生通过动手操作实践运用等活动,让学生体验数学;引导学生从数学角度去观察问题,通过学生自主探索、猜想验证等活动,让学生去创造数学;引
The Mathematics Curriculum Standard states that mathematics teaching is the teaching of mathematics activities. The mathematics activity is the activity of students going through the process of mathematics and the activity of students constructing their own knowledge, which fully shows that students should be the masters of mathematics study. Teachers in teaching should be closely linked with the actual students, starting from the student’s life experience and experience of existing knowledge, to create vivid and interesting situations, so that students close to mathematics; to guide students through hands-on practical activities to enable students to experience mathematics; guide Students observe the problem from a mathematical point of view, through student self-exploration, guesswork and other activities to allow students to create mathematics;
