Abstract

The invention discloses a multifunctional applied mathematics probability event teaching device, which comprises a box body, wherein a sliding groove assembly is arranged in the box body, the sliding groove assembly is composed of sliding groove units, each sliding groove unit comprises a first sliding groove and a second sliding groove, the first sliding grooves which are in butt joint in sequence form a first sliding way, the second sliding grooves which are in butt joint in sequence form a second sliding way, the side wall of the box body is provided with a first notch, an automatic marble device is arranged at the outer end of the first notch, a first rolling ball is arranged in the first sliding way, a second notch is formed in the end, which corresponds to the second sliding way, of the side wall of the box body, a manual marble device is arranged at the outer end of the second notch, a second rolling ball is arranged in the second sliding way, and a detachable shielding plate is arranged on the upper side of the first sliding way. According to the invention, the occurrence probability of events of some scenes can be simulated, the automatic marble device can realize reciprocating rolling of the first rolling ball in the first sliding way, a user can launch the second rolling ball from one end of the second sliding way to slide along the direction of the second sliding way by manually moving the marble device, and the user can better experience the relationship between the collision probability and the related variables through multiple operations.

Description

technical field [0001] The invention belongs to the field of probability demonstration devices, in particular to a multifunctional applied mathematics probability event teaching device. Background technique [0002] Probability and mathematical statistics is an important subject, which plays an important role in middle school mathematics quality education. Probability and statistics are abstract, and with the help of certain teaching tools, students can intuitively observe probability phenomena and study random events, which has extraordinary significance for middle school mathematics teaching. [0003] Existing probability demonstration devices have a single function and are too abstract, which makes it difficult to simulate practical problems, has low joy of operation, and makes it difficult for people to realize better teaching significance. Contents of the invention [0004] The invention provides a multifunctional applied mathematics probability event teaching device...
