Summary:The utility model relates to the technical field of economic management teaching. The utility model discloses a statistical teaching device for economic management science. Bottom plate, a teaching flat plate is mounted at the top end of the bottom plate; grids are arranged on the outer wall of one side of the teaching flat plate; a sliding groove is formed in the outer wall of one side of the teaching flat plate; the number of the sliding grooves is equal to the number of the longitudinal columns of the grids. A sliding plate and a sliding block are slidably connected into the sliding groove.The sliding plate is located on one side of the sliding block. The roughness of the connecting part of the sliding plate and the sliding chute is relatively small; the roughness of the connecting part of the sliding block and the sliding chute is relatively high; in order to solve the problem that synchronous observation is inconvenient when the height of a moving card is adjusted in an existingdevice, the device is prov
