操作材料是幼儿学习数学知识的物质前提和必要条件。在实践中,我体会到为幼儿提供操作材料时应注意以下几点:1.目标性操作材料的合适与否往往直接关系到幼儿获得什么样的学习经验,获得哪些方面的发展。因此,只有把教育意图和要求融进材料之中,才能使之更好地为教育目标服务,发挥最大的功效。如我们用带透明盖的酸奶盒制作了一个摇摇盒,然后准备设计两个六面均为数字的骰子放在摇摇盒中,使之两两相合凑出指定的数字。那么,骰子六个面的数字究竟怎样分配,才最有利于操作呢?以巩固5以内数的组成及其分合关系为例,如果骰子上的数字为1～6,则两两相合的数字常常超过5。如果我们将四面的数字
Operating materials are the material prerequisites and necessary conditions for young children to learn mathematical knowledge. In practice, I realized that the following points should be paid when providing operating materials for young children: 1. The suitability of the targeted operating materials often has a direct bearing on what kind of learning experience young children receive and what aspects they gain. Therefore, only by integrating the educational intention and the requirement into the material can we make it serve the educational goal better and achieve its maximum effectiveness. For example, we made a shaking box with a transparent lid of the yogurt box, and then designed to design two six-sided dice on the shaking box, making them coincide with the specified numbers. So, how to allocate the numbers of the six sides of the dice is the most conducive to the operation? To consolidate the composition of the number within five and its relationship, for example, if the number on the dice is 1 ~ 6, the two numbers coincide Often more than 5. If we will be surrounded by numbers
