26、受具体问题中的数量关系，并用确定的数表示出来，进而逐步发展，体会可以用字母表示变化的数，结合具体的问题体会字母的概括性和简洁性，体会用字母表示数的优越性。 2(注重符号化思想的渗透。 英国著名哲学家、数学家罗素说过:“什么是数学,数学就是符号加逻辑。”本方案在设计的过程中注重符号化思想的渗透，本着由简单到复杂，由具体到抽象的原则，采用观察1 思考、合作探究、动手操作等不同的学习方式，使学生认识到用字母表示数的优越性，感受到字母以它浓缩的形式表达大量信息的优点。 课前准备 教师准备 PPT课件、学情检测卡、课堂活动卡 学生准备 小棒、练习卡片 教学过程 ?情境引入 (情境图展示)宁宁和波波正在看

27、一则新闻:7月6日中午12:00，警方接到110报警 ，在h高速公路上，有x个犯罪嫌疑人驾驶着车牌号为浙BT06XX的出租车，以每小时v千米的速度朝S方向逃跑。警方快速出击，经过t小时的追捕，将这些犯罪嫌疑人成功抓获。 师:观察情境图，你看到了哪些新的表述方式, 预设 生:看到了许多字母。 师:根据以上信息，你认为字母可以表示什么,(学生列举字母可以表示的内容，如字母可以表示速度、方向、数量等，还可以表示高速公路的名称) 2 师(指名):刚才许多同学都谈了自己的想法，你有什么感受,(学生谈感受) 揭示课题。(板书课题) 设计意图:以虚拟的新闻情境图引入，让学生体会到用字母可以表示固定的数、地名

28、、方向、时间等，感受数学与生活的密切联系，有效地激发了学生学习数学的兴趣。 ?探究新知 1(课件出示例4，学生观察，提出问题，小组讨论。 师:通过观察课件，你获得了哪些数学信息, 预设 生1:我知道了一大杯果汁是1200 g，倒了3小杯。 生2:我知道了一小杯果汁是x g。 师:你能用含有字母的式子表示大杯果汁还剩多少克吗, (小组讨论，生汇报;师板书1200,3x) 师:你是怎么想的, 预设 生:一小杯果汁是x g，3小杯果汁总共3x g，还剩(1200,3x)g果汁。 师:根据这个式子，当x等于200时，果汁还剩多少克, (生独立计算，指名板演。当x,200时，1200,3x,1200,3

29、200,600) 3 师追问:当x,300、400时你会计算吗,想一想，算式中的x还可以表示哪些数,最大是多少, 学生通过讨论交流后得出结论:x最大可以表示400，因为当x,400时，3小杯正好是1200 g。 2(小组合作，操作体验例5。 同桌为一个小组，一名同学用小棒摆3个三角形，另一名同学用小棒摆3个正方形，摆完后小组计算共用了多少根小棒，并汇报。 |a|的越小，抛物线的开口程度越大，越远离对称轴y轴，y随x增长（或下降）速度越慢。预设 生:33，34,21，共用了21根小棒。 （1) 与圆相关的概念：师:如果摆x个三角形和x个正方形，共用多少根小棒, (学生小组内交流后汇报) (1)如

30、圆中有弦的条件,常作弦心距,或过弦的一端作半径为辅助线.（圆心向弦作垂线）预设 生1:三角形用了3x根小棒，正方形用了4x根小棒，共用(3x，4x)根小棒。 sin生2:摆一个三角形和一个正方形用7根小棒，摆x个三角形和x个正方形一共用7x根小棒。 A、当a0时师:仔细观察两种方法，你有什么发现, 3x，4x,(3，4)x,7x (3) 扇形的面积公式:扇形的面积 (R表示圆的半径, n表示弧所对的圆心角的度数)4 预设 生:运用了乘法分配律。 师:当x,8时，你能求出用了多少根小棒吗, 3.余弦：(生独立解答) 3(完成教材59页“做一做”。 4(赠名言、激励学生勤奋学习。 师赠言:科学家爱

31、因斯坦在谈成功的秘诀时，写下了一个公式:A,X，Y，Z，A代表成功，X代表艰苦的劳动，Y代表正确的方法，Z代表少说空话。 A,X，Y，Z ? 成功,艰苦的劳动，正确的方法，少说空话 （2）顶点式：设计意图:本节课是用字母表示数的应用，通过学习，使知识能够串联起来，促进学生通过迁移、转化的思想学习新知，体会可以用字母表示变化的数量，用含有字母的式子既可以表示数量，又可以表示数量关系。“ax?bx”形式的式子的简写是一个难点，学生不易理解。让学生亲自摆一摆，在实践中理解含有字母的乘法分配律，从而学会“ax?bx”的简化写法。 5 小学数学, 教学, 字母 一、指导思想：6 五年级首字母填空专项练习
