【教学内容】北师大版小学数学教材一年级上册第59-61页“一起来分类”。【教材分析】“一起来分类”是“分类”这一单元的第二课时。“整理房间”是给定标准让学生分类,而本课时是自定标准进行分类,由于学生已经学会分类的基本方法,所以重点是让学生学会选择不同分类标准的方法,体验分类结果在不同标准下的多样性、灵活性和可变性。感受数学与生活的紧密联系,同时加强培养学生的动手操作及数学表达的能力,激发学生的学习兴趣。
【Content】 Beijing Normal University version of the primary school mathematics textbooks grade 59-61 page “together to classify.” 【Textbook Analysis】 “together to classify” is the second class hour of “class ” this unit. “Finishing the room ” is a given standard for students to classify, and this class is self-defined standard for classification, as students have learned the basic method of classification, so the focus is to enable students to learn different methods of classification criteria to experience the classification results in Diversity, flexibility and variability under different standards. Feel the close connection between mathematics and life, at the same time, strengthen students ’ability of hands-on operation and mathematical expression to stimulate students’ interest in learning.
