首先,引领学生感悟相似美。数学中的几何图形虽比不上美术绘画那么逼真,那么自由浪漫,那么色彩斑斓,但几何图形基本勾画出物体的大致形状,它像美术画中的工笔画,富有图案美,与实物比较具有相似美。那么,在教学中,教师要让学生认识到数学中的图形美,在教具演示或者板书时要从不同的角度演示美观的形体,教师在黑板上作图要规范、要标准,让学生充分感受到图形美。切忌随手乱画, First of all, to lead students to perceive similar beauty. Although the geometry in mathematics is less realistic than the art painting, then it is free and romantic, so colorful. However, the basic shape of the object is delineated by the geometric figure. It looks like the fine brushwork, the beautiful figure in the art, Similar beauty. Then, in teaching, teachers should make students recognize the graphic beauty in mathematics. When teaching aids demonstration or writing a book, they should demonstrate beautiful appearance from different angles. Teachers should make a standard on the blackboard to standardize and make the students fully experience To the graphic beauty. Do not doodle,
