前苏联教育家苏霍姆林斯基说过:“儿童的智慧在他的手指尖上。”数学是一门抽象的学科,小学低年级的学生主要以形象思维为主,数学知识对于他们来说是抽象、枯燥的。随着信息技术的发展,计算机和多媒体对教学方式产生了很大的影响,但是,利用学具动手实践仍然是学生学习数学的重要方式之一,也是教师经常采用的教学方式。动手操作可以把抽象、复杂的数学问题变得简明具体形象,启迪学生的智慧, Sukhomlinski, a former Soviet educator, said: “The wisdom of children is at his fingertips.” Mathematics is an abstract subject. The students in the lower grades of primary schools mainly use image-based thinking. They are abstract and boring. With the development of information technology, computer and multimedia have a great influence on the teaching methods. However, the use of learning tools is still one of the important ways for students to learn mathematics, and is also a teaching method often used by teachers. Hands-on operations can abstract and complex mathematical problems become concise and concrete, inspire students’ wisdom,
