Abstract
The utility model relates to a mathematic special teaching aid which is characterized in that the utility model includes brackets and several figures indication sign, wherein a digit group is provided below each figures indication sign. The digit group comprises ten digital pieces of paper with one side of each fixed on the brackets, which is written zero to nine ten numbers in turn. The brackets below each digit group is provided with the corresponding pattern group which includes fixing rollers, shafts of rolling and conveyor belt, wherein the conveyor belt has nine patterns and moves clockwise or withershins through the fixing rollers engaging with shafts of rolling, making the front of conveyor belt displays zero to nine patterns. The utility model is simple, practical, interesting and very applicable for the math teaching in the primary school.
Description
Technical field
The utility model relates to a kind of teaching aid, the special-purpose teaching aid of particularly a kind of mathematics.
Background technology
At the teaching process of primary school mathematics, at first must teach number of students number, reading, write number, know figure place, just can carry out further mathematical education.But pupil's age is all less, and teaching gets up to exist certain difficulty, and existing teaching method is writing on the blackboard and oral explanation, does not have number form to combine, and the pupil understands more abstract, can not grasp the content of courses faster.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of mathematics simple in structure, visual and understandable, that number form combines special-purpose teaching aid.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is the special-purpose teaching aid of a kind of mathematics, be characterized in, it comprises support, on support, be provided with several figure place direction boards, the below of each figure place direction board is provided with 1 digit groups, described digit groups is made up of the digital scraps of paper that 10 one ends are fixed on the support, is provided with " 0-9 " 10 numerals on the 10 number wastepaper with characters written or printed on it sheets successively; The support of each digit groups below is provided with the corresponding pattern group that is made of fixed idler whell, the axis of rolling and travelling belt, be provided with 9 patterns on the described travelling belt successively, driving-belt makes the front of travelling belt show 0-9 pattern respectively by the cooperation scrolling realization clockwise direction or the anticlockwise transmission of the fixed idler whell and the axis of rolling.
Technical problem to be solved in the utility model can also further realize by following technical scheme.The special-purpose teaching aid of above-described a kind of mathematics is characterized in that described figure place direction board is 4, indicates " individual ", " ten ", " hundred ", " thousand " position from right to left respectively.
The utility model is the numeral of selected earlier digit groups in use, make digital consistent that the pattern number that shows on the travelling belt and digit groups show by the axis of rolling, thereby the teaching of figure place is known in the combination of realization number form simultaneously by set figure place display board.The utility model is simple and practical, and is interesting strong, is applicable to primary school math teaching.
