Abstract

The invention relates to a wheel disk type calculator and a use method thereof, belonging to mathematical teaching tools. The wheel disk type calculator comprises a fixed disk, a rotating disk, a bolt and a nut. The wheel disk type calculator is characterized in that the fixed disk and the rotating disk are installed on the bolt; the fixed disk and the rotating disk are fixed to the bolt by the nut; the fixed disk and the bolt are in stationary fit, and the rotating disk and the fixed disk are in movable fit; same figures with equal radial scale parts are arranged on the fixed disk and the rotating disk; the radial scales of the fixed disk and the rotating disk can be superposed and interchanged; and the sum and difference can be calculated by a track distance generated by motion. The wheel disk type calculator has the advantages of simplicity and convenience for calculation, immediacy in result generation as long as the rotating disk rotates, high intuitionism, accuracy and high speed, is suitable for childhood education, can ensure that a child learns figures as soon as possible and rapidly improve the addition and subtraction calculating ability of children and is suitable for the universal education on child mathematics by all the people.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a roulette calculator and a using method. Background technique [0002] At present, the existing teaching aids for children only use traditional pen calculations and abacus calculations, which are not intuitive enough. Abstract numbers make children prone to weariness, resistance, and even disgust when learning; , difficult to understand, difficult to remember, inconvenient to master, and low efficiency in mental calculation. Contents of the invention [0003] The object of the present invention is to provide a roulette calculator and its usage method, which has intuitive image, convenient operation, easy grasp and easy carrying. It is mainly used for the teaching purpose of children's recognition of numbers and calculation of addition and subtraction. It can quickly improve children's ability to recognize numbers and calculate addition and subtraction, and is suitable for the universal educ...
