罗丹说过:“生活中不是缺少美,而是缺少发现美的眼睛。”对称美是数学美中最典型的代表之一,教学中如果能够带领学生去发现隐藏在数学问题中的对称美,将能够冲淡学生学习数学时的枯燥感,增强学习数学的兴趣。在教学中,我常常在以下几个方面培养学生在解题中感受和发现对称美的意识:一、运用数学图形的对称美寻求解题思路图形的对称美常常体现在对称轴和对称中心。无论是一个图形本
Rodin said: "Symmetry is one of the most typical representatives of mathematics and beauty. If teaching can lead students to discover symmetrical beauty hidden in mathematical problems, , Will be able to dilute the sense of boring students learn mathematics, enhance the interest in learning mathematics. In teaching, I often cultivate the students’ sense of feeling and discovering the symmetry beauty in solving problems in the following aspects: 1. The symmetrical beauty of mathematical graphics is often found in the symmetry axis and the symmetry center. Whether it is a graphic book
