资源描述

16 和 71理解 6 和 7 的基数意义(重点)突破建议:一、在观察中数数,认识 6 和 7 的基数意义。充分利用学生已有经验通过主题图提供的资源数数。可以提出以下问题:教室里有几个同学在做值日?你是怎么数的?用几来表示?教室中还有哪些物品的数量也是 6?请你把它们找出来。二、在操作中数数,认识 6 和 7 的基数意义。可以在计数器拨珠,摆点子图等操作活动中数数,直观认识 6 和 7 的基数意义并以此为基础研究数与数之间的关系。可以提出以下问题:在计数器上拨出 5 个珠子以后,问:再添上 1 个珠子是几个珠子?让我们一起来数一数。把计数器上珠子和我们手中的圆片一一对应起来,边摆边数。2区分 6、7 的基数意义和序数意义(难点)突破建议:在对比中观察,认识 6 和 7 的基数意义。因为学生总是出现把几和第几混淆的情况,因此可以用圆片来帮忙,一个圆片对应一个物品,用圆的个数表示几和第几,能够使学生通过抽象直观的方式辨析出第几指的是一个,而几表示几个的意思,从数量上突出差异。
