Description
Technical field
The utility model relates to a kind of teaching aid, a kind of specifically infant mathematics education demonstrator.
Background technology
In present preschool child's formative education, teaching for mathematics generally is some simple addition subtraction multiplication and division computings, this need write the limit in the blackboard top by teacher and say, also need to take some cards or spillikin to do demonstration, so that the student can be fully understood, the weak point of this method is: tell about the comparison difficulty, and directly perceived inadequately for the demonstration of numeral, attractive force to the student is not high, causes efficiency of teaching lower.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, demonstrating visual, is convenient to move, and helps improving the infant mathematics education demonstrator of infant mathematics quality of instruction.
In order to reach above purpose, the technical scheme that the utility model adopted is: this infant mathematics education demonstrator, by box body, folding, demonstration board and bead constitute, demonstration board is fixed on the box body by folding, bead is placed in the box body, it is characterized in that: on described demonstration board, be provided with the first digital display channel, the second digital display channel and operation result display channel, between the first digital display channel and the second digital display channel, be provided with the sign of operation displaying block, between the second digital display channel and operation result display channel, be provided with the outcome symbol displaying block, at the first digital display channel, all be provided with the bead inserted link in the second digital display channel and the operation result display channel, bead is inserted on the bead inserted link.
The utility model is also implemented by following measure: the middle part of described box body is provided with the bead storage tank.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, demonstrating visual, is convenient to move, and has improved the infant mathematics quality of instruction, has reduced teacher's labour intensity, has improved work efficiency.
