Description
Technical field
The utility model relates to a kind of teaching equipment, is specially a kind of College Maths probability model teaching aid, belongs to teaching aid technical field.
Background technology
Probability, because being compare abstract concept, in College Maths theory of probability course, if can coordinate explanation by the demonstration of probability teaching aid, can make student be easier to understand and grasp.And at present, because being applicable to the probability teaching aid of teaching, student can only remove to understand probability theory by teacher explains, this mode of giving lessons make student to the understanding of probability and Grasping level not high, teacher's also very painstaking in the process explained.Therefore, be badly in need of a kind of teaching probability teaching aid and carry out cooperation teaching.
Summary of the invention
The purpose of this utility model is just to provide a kind of College Maths probability model teaching aid to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of College Maths probability model teaching aid, comprise base, probability plate, bar shaped post, expansion link and drawing plate, it is characterized in that: described probability plate is fixedly connected with base, described bar shaped post and drawing plate are all connected with the form of chute with probability plate, and described expansion link two ends are rotatably connected from different bar shaped column bottoms respectively.
Preferably, be provided with scale on the left of described probability plate, probability plate is longitudinally uniformly distributed the chute of more than three, and chute is positioned at probability plate 2/3 part from front to back, and in chute, the left and right sides is provided with protruding rectangular column, and chute rear portion is provided with different colors.
Preferably, described bar shaped column top is provided with draw ring, and bar shaped post both sides are provided with the groove corresponding with probability plate chute internal projection rectangular column.
Preferably, described expansion link is the middle expansion link that carefully two ends are large.
Preferably, described drawing plate is also provided with sector diagram, and on the right side of drawing plate, is provided with hand handle.
Compared with prior art, the beneficial effects of the utility model are: this College Maths probability model teaching aid integrates bar shaped statistical graph, broken line graph and fan-shaped statistical graph, the lively imagination dissimilar probability is demonstrated out, colors different in chute can be seen by regulating bar shaped post, further, expansion link is followed bar shaped post and changes, the demonstration of probability can be expressed intuitively, demonstration more intuitively, more eye-catching, being beneficial to student to understand and this subject of learning probability, when demonstrating, there is eye-catching, easy-operating feature.
