设计意图4—5岁幼儿是认识图形的重要时期,能不受图形大小、颜色和摆放位置的影响,正确辨认和命名。同时这个年龄段的幼儿以具体形象思维为主,能根据事物的表面属性概括分类,但容易忽略隐性特征。根据《指南》科学领域“数学认知”目标:4-5岁幼儿“能感知和发现常见几何图形的基本特征,并能进行分类。”“科学探究”目标:4-5岁幼儿“能对事物或现象进行观察比较,发现其相同与不同。”我设计了“图形宝宝”活动,目的是让幼儿动手尝试从不同角度观察事物,
Design Intent 4-5-year-olds are an important part of recognizing graphics and can recognize and name correctly regardless of the size, color and placement of the graphic. At the same time, young children in this age group are mainly based on specific image thinking, and can be classified according to the surface properties of things, but it is easy to ignore the hidden features. According to the Guide to Science in the field of “Mathematical Awareness” goal: 4-5 year-old children “can perceive and discover the basic features of common geometry and can be classified.” “ 5-year-olds ”can observe and compare things or phenomena and find that they are the same and different.“ ”I designed the“ graphic baby ”activities to let young children try to observe things from different perspectives,
