一、说教材我说课的内容是义务教育小学数学(人教版)六年制第十二册第二单元中“圆锥体积”的第一课时。教材首先创设了一个问题情境,引导学生实验、探索,然后引导学生通过实验,探究圆锥与圆柱体积之间的关系。有利于进一步发展学生的空间观念,为进一步解决一些实际问题打下基础。1.教学目标(1)知识方面:理解并掌握圆锥体积公式的推导过程,学会运
First, the textbook I said the content of the course is compulsory primary school mathematics (PEP) six years of the twelfth unit in the second unit “conical volume ” of the first class hour. Textbook first created a problem situation, guide students to experiment, explore, and then guide students through experiments to explore the relationship between cone and cylinder volume. This will help to further develop the students’ space concept and lay the foundation for further solving some practical problems. 1 teaching objectives (1) knowledge: understand and grasp the convolution volume formula of the derivation process, learn to transport
