教幼儿认识平面几何图形是幼儿园计算教学内容之一。通过几何图形的认识,要求幼儿知道所学图形的名称及其主要特征,以增长他们的知识,培养和发展他们的观察能力、空间想象能力和分析比较能力。同时为美工课及建筑游戏的开展打下基础。平面几何图形涉及到边、角的概念,所以首先必须利用实物讲清什么叫边、角,什么叫对边、对角。用小黑板,讲黑板的四周边沿叫边。然后叫小朋友数数小黑板有几条边,数清边后,再叫他们数数小黑板有几个角。进一步指出,上下两条对着的边,叫对边。要求小 Teach children to recognize plane geometry is one of kindergarten computing teaching content. Through the understanding of geometry, young children are required to know the names of the graphics they learn and their main characteristics in order to increase their knowledge, develop and develop their observation ability, spatial imagination ability and comparative analysis ability. At the same time for the art classes and construction games to lay the foundation. Plane geometry involves the concept of edge, angle, so first of all we must first make use of the real thing to clarify what is the edge, angle, what is the opposite, diagonal. With a small blackboard, say blackboard around the edge called edge. Then called the number of small children there are a few black side of the board, the number of clear side, and then call them a few small blackboard a few horns. Further pointed out that the two opposite sides, called the opposite side. Small requirement
