Summary:The utility model relates to a relation analysis operator for primary school mathematics problems, which is mainly composed of a body (1) of an operating disk, a physical model (2), an indicating needle (3) and a point dividing block (4), wherein, the body (1) is provide with a trackway for putting the physical model (2) to move, a trackway for putting the indicating needle (3) to move, and a trackway for putting point dividing block (4) to move, and both sides of the positive surface are respectively provided with a row of images (104) of real objects. The indicating needle and the point dividing block which can be moved on the trackway are arranged on the positive and negative surfaces of the body of the operating disk and have the same function. The abstract mathematical analysis of the primary mathematics can be transformed into the operational analysis for operating by hands of students, a medium is provided for image thinking which is need to be established for understanding primary school mathematics problems, and the utility model is provide with functions and effects of relationship analysis and operation for all types of primary school mathematics problems.
