数据的收集与整理 3 数据的表示教案教学设计
创设情境，导入新课：你对母亲知多少师问1：我们5月份刚过了一个重要的节日，你知道是什么吗？----母亲节。师问2：那你知道妈妈的生日吗？（举手示意），每个妈妈都知道自己孩子的生日，请不知道的同学回家了解一下，多关心一下自己的父母。师问3：那你知道妈妈最爱吃的菜吗？你可以选择知道、不知道或者是没有爱吃的（拖动白板上相对应的表情符号）。请大家用不同的手势表示出来。我找3名同学统计各组的数据，写在黑板上（随机找3名学生数人数）。下面我来随机采访一下：你妈妈最喜欢吃的菜是什么？（教师随机采访，结合营养搭配和感恩教育）
丰富的图形世界 展开与折叠教案教学设计
设计意图：题目1是判断能否折叠形成立体几何，本题可以研究学生对常见几何体的把握是否成熟。题目2是考察正方体的展开图，一方面可以研究学生对几何体的把握，另一方面可以引导学生思考，引出下面要学习的内容。）学生预设回答：题目一：学生应该很容易的说出折叠后形成的立体图形。题目二：①运用动手操作的方法，剪出题目中的图形，折叠后对题目做出判断。 ②利用空间观念，复原展开图，发现6的对面是1，2的对面是4，5的对面是3，进而做出判断。教师引导语预设：① 当学生运用动手操作的方法，可以让学生动手实践一下，下一步再引导学生观察正方体，发现规律。② 当学生运用空间观念，教师要放慢语调，和学生一起想象，锻炼学生空间想象能力。

人教版高中地理选修1第三章第一节地球的早期演化和地质年代教案
地质年代可分为相对年代和绝 对年龄（或同位素年龄）两种。相对地质年代是指岩石和地层之间的相对新老关系和它们的时代顺序。地质学家和古生物学家根据地层自然形成的先后顺序，将地层分为5代12纪。即早期的太古代和元古代（元古代 在中国含有1个震旦纪），以后的古生代、中生代和新生代。古生代分为寒武纪、奥陶纪、志留纪、泥盆纪、石炭纪和二叠纪，共7个纪；中生代分为三叠纪、侏罗纪和白垩纪，共3个纪；新生代只有第三纪、第四纪两个纪。在各个不同时期的地层里，大都保存有古代动、植物的标准化石。各类动、植物化石出现的早晚是有一定顺序的，越是低等的，出现得越早，越是高等的，出现得越晚。绝对年龄是根据测出岩石中某种放射性元素及其蜕变产物的含量而计算出岩石的生成后距今的实际年 数。越是老的岩石，地层距今的年数越长。
