The invention relates to the field of mathematics teaching, and especially relates to a dice shaking device for mathematic probability teaching. A technical problem to be solved by the invention is toprovide the dice shaking device which enables dices not to fall to the ground, is higher in dice shaking efficiency and is higher in conviction after dice shaking. In order to solve the above technical problem, the invention provides the dice shaking device, and the device comprises a circular plate. The bottom of the circular plate is vertically provided with supporting legs, and the center of the bottom of the circular plate is provided with a shaking apparatus. A shaking part of the shaking apparatus is located above the circular plate, and the top of the circular plate is provided with anopening and closing apparatus. The shaking part of the shaking apparatus is located in an opening and closing part of the opening and closing apparatus. According to the invention, the shaking apparatus is used for shaking dices, and the opening and closing apparatus is used for covering or opening the shaking apparatus, thereby enabling a teacher to see the dices shaken on the moving part of theshaking apparatus, and achieving a higher shaking efficiency during the shaking of dices.
