1、购物策略教学设计汉中市陕飞二小曾蕊教学内容：北师大版本五年级第十册第六单元第81 页教材分析：本课内容是北师大版实验教科书第81 页的内容，这是一节综合运用知识解决生活中有关购物问题课，目的是让学生在解决实际问题的过程中，感受数学在日常生活中的作用，来体验解决问题策略的多样性，并在此基础上形成自己解决问题的某些策略。发现购物策略是多种多样的，体会数学是帮助人们做出判断和进行决策的工具。学情分析：学生在三年级已经学习了货比三家，四年级学习了精打细算，已经掌握了在保证质量的情况下，同样的商品选择价格便宜的购物策略。在此基础上，本课继续学习新的购物策略，让学生体验购物策略的多样性，培养学生的优化意识
2、。例题以实践活动的方式呈现，让学生在熟悉的生活情景中，将数学知识应用于实践解决问题。教学目标：知识与能力1、理解“买一送一”、“打折”等促销策略；2、根据实际情况，选择最有利于消费者的策略来购物。过程与方法1、掌握“质量相同的商品，选择价格便宜的”“价格相同的商品，选择数量较多的”两种不同的购物策略；2、体验购物策略的多样性，培养学生的优化意识。情 感 态 度 与 价 值 观体验数学课与现实生活的紧密联系，体会数学课程的工具性，发展学生学习数学的兴趣。教学重点：根据实际情况，选择最有利于消费者的策略来购物，培养学生的优化意识。教学难点：掌握“在保证质量，价格相等的情况下，选择数量多的商品”的购
3、物新策略。教学准备：制作课件。教学过程：（一）创设情境，初步感知“策略”。播放田忌赛马故事。师：同学们，听了这个故事，你们知道田忌为什么在第二次赛马中转败为胜了吗？生：因为，田忌（孙膑）运用了策略。师：是啊，有的同学说，他们运用了策略！（板书：策略）（指着板书）那什么是策略呢？策略是根据形势发展而制定的行动方针或解决办法。师：对待比赛和战争我们要讲究策略，其实，生活中很多时候我们都要讲究策略，广告有广告策略，销售有销售策略，老师上课要有教学文档编码:CW2K3F2Z9N3 HW7J4L1T1K1 ZG6T6H7L1K9文档编码:CW2K3F2Z9N3 HW7J4L1T1K1 ZG6T6H7L1
