Zusammenfassung:The utility model belongs to the field of mathematical teaching aids and particularly relates to a mathematical operation magic wheel suitable for preschool children or low-grade children to use. The mathematical operation magic wheel is characterized by consisting of more than two decagonal prism monomers which are connected into a whole through a rotary shaft; wherein each prism monomer can be independently rotated on the rotary shaft; one end of the rotary shaft is provided with a convex plate; and the screw thread of the other end of the rotary shaft is provided with a nut. The mathematical operation magic wheel has the advantages of being simple in structure and is capable of increasing learning interests and improving the learning effect.
