内容简析“圆锥的体积”是人教版《义务教育课程标准实验教科书·数学》六年级下册的内容,是学生在学会求圆面积和求长方体、圆柱的体积的基础上进行教学的。其教学目标:1.通过计算机动态的引入和学生动手操作实验,推导出圆锥体体积的计算方法,并能运用公式计算圆锥体的体积;2.通过学生动脑、动口、动手,培养学生的思维能力和空间想象能力;3.培养学生个人的自主学习能力和小组合作学习的能力。其教学重点与难点,是掌握圆锥体体积公式的推导。
Content analysis “volume of cones ” is the content of the sixth edition of compulsory education curriculum standard experimental textbook mathematics version of the PEP, is the students on the basis of learning the circle area and the cuboid, cylindrical volume of. Its teaching objectives: 1. Through the introduction of computer dynamics and student hands-on experiments, derived cone volume calculation method, and can use the formula to calculate the cone volume; 2 through the students brain, mouth, hands-on training students Thinking skills and spatial imagination; 3 students develop their own independent learning ability and team learning cooperative ability. Its teaching focus and difficulty, is to understand the cone volume formula derived.
