教学内容:义务教育课程标准实验教科书小学数学六年级下册第二单元《圆柱和圆锥》学情分析:学生已经掌握了圆柱和圆锥体积的计算方法,已了解等底等高的圆柱和圆锥的体积关系,但对圆柱和圆锥等积变形的知识尚未了解,本节课将引导学生进一步探究它们之间的关系。教学目标1)理解掌握圆柱和圆锥之间的三种特殊关系。2)运用这三种特殊关系解决实际问题。3)培养学生的合作探究意识。教学重、难点1)探究圆柱和圆锥之间的三种特殊关系。
Teaching content: Compulsory education curriculum standard experiment textbook elementary school mathematics sixth grade volume second unit “column and cone” Analysis of the situation: Students have mastered the calculation method of cylinder and cone volume, However, the knowledge of cylinder and conic isomerism deformation is not yet known. This lesson will guide students to further explore the relationship between them. Teaching Objectives 1) Understand the three special relationships between a cylinder and a cone. 2) Use these three special relationships to solve practical problems. 3) cultivate students’ awareness of cooperation and exploration. Teaching heavy, difficult 1) to explore the cylinder and the cone between the three special relations.
