动手实践是学生学习数学的重要方式。在动手中学会数学知识、掌握数学技能是小学数学教师教学的重要目的。教学中,教师要本着以学生为主的理念,积极创设情境,培养学生的逻辑思维能力,让学生在动手实践中发现规律、内化规律,得出结论。这样从感性上升到理性,又从理性回归到实践,不仅有利于发展学生的思维能力,而且能加深学生对数学知识的深入理解和掌握。 Hands-on practice is an important way for students to learn math. Learning the mathematics knowledge and mastery of math skills in the hands of primary school mathematics teachers is an important goal of teaching. Teaching, teachers should be based on the concept of students, and actively create the situation, develop students’ ability to think logically, so that students in the hands of the law found that the laws of internalization, draw conclusions. So from the emotional to rational, but also from the rational return to practice, not only conducive to the development of students ’thinking skills, but also to deepen students’ understanding and mastery of mathematical knowledge.
