创新点这节课尝试用“自主探索-遇到问题-解决问题”的方式去学习使用计算器,把练习设计成了比赛、游戏等多种形式,把口算、笔算、混合运算、用计算器计算有机地结合在一起。把计算器真正作为解决问题的工具,学生在探索的过程中学会了解决数学问题可以有多种方法,也学会了在计算器的帮助下去探索发现数学规律,把学生从一些繁重的计算中解放出来,改变学生的学习方式,使学生有更多的精力投
Innovations This lesson attempts to learn to use calculators in a way that “learns autonomously - encounters problems - solves problems.” The exercises are designed in games, games, and more. Calculator calculations are organically combined. The calculator really as a tool to solve the problem, students in the exploration process to learn to solve mathematical problems can have a variety of ways, but also learn to use the calculator to explore the discovery of mathematical laws, the liberation of students from some heavy calculations Out, change the way students learn, so that students have more energy cast
