The invention discloses a movable mathematics teaching board, and particularly relates to the technical field of teaching appliances, the movable mathematics teaching board comprises a flat plate, a plurality of balls, four self-locking universal wheels and a teaching board body, the middle part of the upper end of the flat plate is provided with a shell II, and the right part of the lower end of the teaching board body is provided with a limiting plate; one side of the rear end of the teaching board body is provided with a mathematical model used for demonstrating a mathematical normal distribution function. According to the movable mathematics teaching board, the horizontal sealing unit is moved backwards, a notch is formed in a cavity jointly formed by the first baffle and the second baffle, a plurality of balls move downwards through the notch, and after the balls are blocked by the stop levers, the falling balls enter the cavity formed by every two adjacent partition plates respectively, and then the balls fall into the cavity formed by every two adjacent partition plates. The normal distribution function curve is drawn, a structure related to mathematics is arranged, demonstration is performed in a dynamic form, understanding of students on the normal distribution function can be deepened in an auxiliary mode, and the practicability of the device is improved.

    本发明公开了一种移动式数学教学板,具体涉及教学用具技术领域,包括平板、若干圆球、四个自锁式万向轮和教学板本体,所述平板上端中部设有外壳二,所述教学板本体下端右部设有限位板,所述教学板本体后端的一侧设有用于演示数学正态分布函数的数学模型。本发明所述的一种移动式数学教学板,将水平封闭单元向后移动,使由两个挡板一和挡板二共同组成的空腔出现缺口,并使若干圆球经该缺口向下移动,后经若干挡杆阻隔后,若干下落的圆球分别进入由相邻的两个隔板组成的空腔内,勾勒出正态分布函数曲线,通过设置有关数学方面的结构,以动态的形式演示,可以辅助加深学生对正态分布函数理解,提高该装置的实用性。
