Abstract
The utility model discloses a calculator for primary school mathematics teaching. The calculator comprises a shell, a first transmission shaft, a second transmission shaft, a rotating handle and rotary disks. The shell is internally provided with a first cavity and a second cavity. The first transmission shaft is arranged in the first cavity. The rotating handle is connected with one end of the first transmission shaft. The other end of the first transmission shaft is connected with the inner wall of the shell. The rotating handle is provided with a return spring. One end of the return spring is connected with the rotating handle, and the other end of the return spring is connected with the shell. Both the first transmission shaft and the second transmission shaft are provided with the rotary disks which are provided with a plurality of number or operation symbols. According to the calculator, the random mathematics practice is carried out through the arrangement and combination of any number and operation symbol arranged on the rotary disks, the interesting is raised, the learning interest and learning effect of students are greatly raised, and the calculator has the characteristics of reasonable design, simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of teaching auxiliary device, relates in particular to a kind of primary school math teaching counter.
