在小学的教学和学习的过程中,大部分的数学公式都是通过一步又一步的推导得来的,特别是在求几何图形的面积、立体几何的体积的时候,都是将许多未知的量设为已知,将许多陌生的量转变为熟悉的量,让学生在轻松的学习中获得了新的知识,培养了学生的创新意识和实践能力.下面就圆柱体积教学来简单说下我的观点,希望大家采纳.一、教学目标1.理解公式的推导过程、掌握计算公式想要得到圆柱的体积公式,首先要做的就是推导公式,我们可以通过设一系列的未知数,将不熟悉的量转变为自己
In the process of teaching and learning in primary schools, most of the mathematical formulas are deduced step by step. Especially when calculating the area of the geometric figure and the volume of the three-dimensional geometry, many unknown quantities Set as known, many unfamiliar amount into a familiar amount, so that students learn easily gained new knowledge, cultivate the students’ sense of innovation and practical ability. Following on the cylinder volume teaching to put my simple First, the teaching objectives 1. Understand the derivation process of the formula, grasp the formula To get the formula of the cylinder volume, the first thing to do is to derive the formula, we can set a series of unknowns, unfamiliar Turn into yourself
