皮亚杰指出:“幼儿学习数学是通过对事物的反复操作,从中抽象出事物的数、形、序等结构关系。”实践证明,材料是操作的物质基础,为幼儿设计提供适宜的数学操作材料,对幼儿的数学能力发展尤为重要。的确如此,幼儿数学能力的发展,是在不断操作和实践中获得的,为了让能够幼儿充分地直接感知和实际操作,教师势必需要创设符合 Piaget pointed out: “Early childhood learning mathematics is through the repeated operation of things, abstracted from the number of things, shape, sequence and other structural relationships.” Practice has proved that material is the material basis for the operation, for young children to provide appropriate design Mathematical manipulation of materials, the development of young children’s mathematical ability is particularly important. Indeed, the development of young children’s mathematical abilities is achieved through continuous operation and practice. In order to be able to fully understand and operate young children directly, teachers are bound to have to create a
