通过实践活动构建能力数学教学中的很多知识只有学生亲身的积极主动参与、动手实践、自主探究,才能内化为学生自己的知识,培养学生的创新意识。在教学实践中,我们要为学生创设宽松的自主探究的空间,把学习的主动权还给学生,让每个学生根据自己的体验,用自己的思维方式,去探索、去发现、去创造性地获得有关的数学知识。如学生在学习正方形四条边的关系时,我让学生观察、猜想、验证正方形四条边都相等 Building capacity through practical activities A lot of knowledge in mathematics teaching Only students’ active participation, hands-on practice and self-exploration can internalize students’ own knowledge and cultivate students’ innovative awareness. In teaching practice, we should create a relaxed room for self-exploration for students and return the initiative of study to students so that each student can explore, discover, and creatively use his own way of thinking according to his own experience Get relevant mathematical knowledge. As students learn the relationship between the four sides of the square, I let the students observe, guess, verify that the four sides of the square are equal
