大班数学游戏教案：城堡夺旗（8的分合法）
准备：数字卡 棋盘 不同颜色的棋子 旋转六面体 各色旗 扑克牌 玩法：每组5名幼儿，一幅棋盘，每位幼儿一套1——7的扑克牌，每名幼儿持一粒不同颜色的棋子，将各自的棋子放在起点，按照自己的标志次序轮流掷旋转六面体，掷出数字几，就向前走几步，如果走到没有图案的格内，就让下一位幼儿掷旋转六面体；如果走到有图案的格子内，就大声说出图案的数量，并向其他幼儿提问该数字和哪一个数字合起来是8，然后与同伴一起从自己的数字卡中拿出相应的数字卡，拿对的幼儿向前走一步，拿错的幼儿原地不动，看谁先走到终点，谁就在城堡的最底层插一面与自己棋子颜色相同的彩旗。游戏反复进行，谁的彩旗第一个到达城堡的顶端，谁就取得胜利。
《拒绝手机，排除干扰》主题班会教案
一、班会背景：手机作为现代高科技的产物，已被越来越多的中学生所拥有，并逐渐地走进了学校，甚至走向课堂。由于高中生自控能力较差，对合理使用手机的认识不够，因此，无法摆脱手机的诱惑，从而影响了正常的学习和生活。最终导致了成绩下降。二、班会目标：1、通过班会，达到教育、自我教育的目的，并让同学们清楚地认识到，在校园里应当禁止使用手机。2、以探讨使用手机的利弊作为契机，折射出对一切高科产物都应辨证接受，真正体现它的价值。3、培养同学们人生观和价值观。三、活动准备：组织班委干部开会，搜集主题班会材料，讨论并确定班会发言内容，书写教案和制作课件。四、班会过程：1、学习“纪律六条”2、讨论中学生使用手机的弊端（同学A、同学B、同学C代表发言）（1）聊天打游戏看视频，影响休息，严重影响学业。多数家长反映，孩子用手机谈论学习的内容少，用于同学之间联系或发短信的多。
《我们携手走向明天》主题班会教案
一、组织目的：1．在形成新集体时，同学之间难以融合,唯我独尊的现象严重，且同学之间还存在互不服气，相互排斥的不友好现象。针对此现象，按照校政教处的要求，组织以“我和我的集体”为中心的主题班会——《我们携手走向明天》，旨在增强集体凝聚力，唤起学生对集体的热爱、对同学的友爱之情。2．力争通过此次班会，调动尽可能多的同学参与到建设一个积极向上、团结协作的集体中来。并在班会中发现同学们的特长，增进彼此的了解，促进友谊的发展。 二、准备步骤：1．召开班委会，讲明以上目的。调动班委的积极性，出谋划策，着手准备。 2．主要负责人班长、宣委构思班会内容，注意从本班现实中搜集素材。3．找班内有号召力的同学谈心，激发其参与活动的热情，并引导其在某些方面作表态。4．审查班长、宣委的组织稿件。5．审查有关人员的发言稿, 引导其从积极、正面的角度调动同学们爱集体、尊重他人的热情。
《拥抱亲情-感恩父母》主题班会教案
“正好啊，老树根是最适合坐下来休息的。来啊！孩子，坐下，快坐下来休息一下。”男孩坐了下来。树好快乐。她高兴得留下了流下了泪水……（故事结束后，课件出示父母辛苦劳作的图片，出示一组家庭生活图片，学生思考感悟。）请学生谈由图片和歌曲获得的感受和体会：“你想到了什么”？学生自由发言。甲：这就是我们的父母，他们无怨无悔，不求回报，真是可怜“天下父母心”啊！播放歌曲《天下父母心》：然而在日常生活中，我们总会与父母发生分歧甚至冲突顶撞，还常常埋怨父母的啰嗦。我们的母亲因为儿子的顽皮而无奈的哭泣；我们的父亲因为女儿的懒惰而叹气；请看小品：《丁丁在家里》（由部分学生和家长代表合演，主要凸显月休孩子在家不听父母教导，过于沉迷网络游戏，不写作业，不能按时作息而家长无可奈何的现象）。
《远离手机 拒绝诱惑》主题班会教案
⑦使用手机会妨碍学校的教育教学秩序。上课时有的同学手机未关机，突然来电话，影响全体同学听课。会给整个教室带来不愉快的情绪。⑧手机对人有辐射。许多广告只说手机有多少多少先进功能，却从未提对人体伤害。对人体是否造成不利的影响，医学界可谓众说纷纭，最近权威医学杂志《柳叶刀》的手机报告显示，使用手机造成记忆力受损、睡眠紊乱、头痛、癞痫及血压上升的现象，而儿童，青少年受影响的可能更大。大部分国家通用的手机系统GSM频率为900和1800MHz,其振动的电子过程有机会对人体健康造成影响,主要是对脑部及精神状态的影响. 而且手机振动所散发出的电磁波可能会导致青少年大脑的神经出现病变。青少年正处在生长发育的黄金阶段,如果因为手机而对身体伤害,岂不追悔莫及。
《珍爱生命 预防溺水》 主题班会教案
（2）如何开展岸上急救 第一步：当溺水者被救上岸后，应立即将其口腔打开，清除口腔中的分泌物及其他异物。如果溺水者牙关紧闭，要从其后面用两手的拇指由后向前顶住他的下颌关节，并用力向前推进。同时，两手的食指与中指向下扳颌骨，即可搬开他的牙关。 第二步：控水。救护者一腿跪地，另一腿屈膝，将溺水者的腹部放到屈膝的大腿上，一手扶住他的头部，使他的嘴向下，另一手压他的背部，这样即可将其腹内水排出。 第三步：如果溺水者昏迷，呼吸微弱或停止，要立即进行人工呼吸，通常采用口对口吹气的方法效果较好。若心跳停止还应立即配合胸部按压，进行心脏复苏。心肺复苏的目的在于尽快挽救脑细胞，避免因缺氧引起细胞坏死。因此施救越快越好，同时注意要在急救的同时，要迅速打急救电话，或拦车送医院。
北师大初中八年级数学下册一元一次不等式与一次函数的关系教案
解析：先利用正比例函数解析式确定A点坐标，然后观察函数图象得到，当1＜x＜2时，直线y＝2x都在直线y＝kx＋b的上方，于是可得到不等式0＜kx＋b＜2x的解集．把A(x，2)代入y＝2x得2x＝2，解得x＝1，则A点坐标为(1，2)，∴当x＞1时，2x＞kx＋b.∵函数y＝kx＋b(k≠0)的图象经过点B(2，0)，即不等式0＜kx＋b＜2x的解集为1＜x＜2.故选C.方法总结：本题考查了一次函数与一元一次不等式的关系：从函数的角度看，就是寻求使一次函数y＝ax＋b的值大于(或小于)0的自变量x的取值范围；从函数图象的角度看，就是确定直线y＝kx＋b在y轴上(或下)方部分所有的点的横坐标所构成的集合．三、板书设计1．通过函数图象确定一元一次不等式的解集2．一元一次不等式与一次函数的关系本课时主要是掌握运用一次函数的图象解一元一次不等式，在教学过程中采用讲练结合的方法，让学生充分参与到教学活动中，主动、自主的学习.
北师大初中八年级数学下册利用四边形边的关系判定平行四边形教案
解：四边形ABCD是平行四边形．证明如下：∵DF∥BE，∴∠AFD＝∠CEB.又∵AF＝CE，DF＝BE，∴△AFD≌△CEB(SAS)，∴AD＝CB，∠DAF＝∠BCE，∴AD∥CB，∴四边形ABCD是平行四边形．方法总结：此题主要考查了平行四边形的判定，以及三角形全等的判定与性质，解题的关键是根据条件证出△AFD≌△CEB.三、板书设计1．平行四边形的判定定理(1)两组对边分别相等的四边形是平行四边形．2．平行四边形的判定定理(2)一组对边平行且相等的四边形是平行四边形．在整个教学过程中，以学生看、想、议、练为主体，教师在学生仔细观察、类比、想象的基础上加以引导点拨．判定方法是学生自己探讨发现的，因此，应用也就成了学生自发的需要，用起来更加得心应手．在证明命题的过程中，学生自然将判定方法进行对比和筛选，或对一题进行多解，便于思维发散，不把思路局限在某一判定方法上.
北师大初中八年级数学下册一元一次不等式与一次函数的综合应用教案
解析：(1)根据题设条件，求出等量关系，列一元一次方程即可求解；(2)根据题设中的不等关系列出相应的不等式，通过求解不等式确定最值，求最值时要注意自变量的取值范围．解：设购进A种树苗x棵，则购进B种树苗(17－x)棵，(1)根据题意得80x＋60(17－x)＝1220，解得x＝10，所以17－x＝17－10＝7，答：购进A种树苗10棵，B种树苗7棵；(2)由题意得17－x172，所需费用为80x＋60(17－x)＝20x＋1020(元)，费用最省需x取最小整数9，此时17－x＝17－9＝8，此时所需费用为20×9＋1020＝1200(元)．答：购买9棵A种树苗，8棵B种树苗的费用最省，此方案所需费用1200元．三、板书设计一元一次不等式与一次函数关系的实际应用分类讨论思想、数形结合思想本课时结合生活中的实例组织学生进行探索，在探索的过程中渗透分类讨论的思想方法，培养学生分析、解决问题的能力，从新课到练习都充分调动了学生的思考能力，为后面的学习打下基础.
