Abstract
A mathematics teaching assistive device relates to a teaching aid, and especially belongs to an assistive device aiming at mathematics teaching. The device is characterized in that: the device comprises a support (2), and digit indicator boardd (1) arranged on the support. A number set (3) is arranged below each digit indicator board. The number set is composed of 10 number paper sheets with one ends fixed on the support. The 10 number paper sheets are sequentially provided with 10 numbers which are 0-9. A corresponding pattern set composed of a fixed roller (6), a rotation shaft (7) and a conveyer belt (5) is arranged on the support below each number set. Each conveyer belt is provided with 9 patterns (4). With cooperative rotation of the fixed roller and the rotation shaft, the conveyer belt can realized clockwise or anticlockwise conveying, such that the patterns 0-9 can be respectively displayed on the front face of the conveyer belt. The assistive device is simple, practical, highly interesting, and has positive effects of easy teaching and easy understanding.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly belongs to a kind of appurtenance to mathematical education.
Background technology
In 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 because pupil's age is little, teaching gets up to exist certain difficulty, and existing teaching method only limits to 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 soon.
The utility model content
The purpose of the utility model promptly is to provide a kind of novel mathematical education appurtenance, with the purpose that reaches simple in structure, visual and understandable, number form combines.
The mathematical education appurtenance that the utility model provided; It is characterized in that; It comprises support, on support, is provided with 2～6 units direction boards, and 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 numbered scraps of paper successively; The support of each digit groups below is provided with the corresponding pattern groups that is made up of fixed idler whell, the axis of rolling and travelling belt; Be provided with 9 patterns on the described travelling belt successively; Travelling belt makes the front of travelling belt show 0-9 pattern respectively through the cooperation scrolling realization CW or the anticlockwise transmission of the fixed idler whell and the axis of rolling.
In the ordinary course of things, above-mentioned figure place direction board has 4, is designated as " individual " " ten " " hundred " " thousand " from right to left successively.
The utility model in use; The first numeral of selected digit groups makes digital consistent that the pattern number that shows on the travelling belt and digit groups show through the axis of rolling, thus the combination of realization number form; Know the teaching of figure place simultaneously through set figure place display board; Have simple and practically, interesting strong, be prone to the understandable good effect of religion.
Description of drawings
Accompanying drawing is the structural representation of the utility model.Wherein,
1, figure place direction board; 2, support; 3, digit groups; 4, pattern; 5, travelling belt; 6, fixed idler whell; 7, the axis of rolling.
Embodiment
Mathematical education appurtenance as shown in the figure, that the utility model provided, it comprises support 2, on support, is provided with 4 units direction boards 1, is designated as " individual " " ten " " hundred " " thousand " from right to left successively.The below of each figure place direction board is provided with 1 digit groups 3, and 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 numbered scraps of paper successively; The support of each digit groups below is provided with the corresponding pattern groups that is made up of fixed idler whell 6, the axis of rolling 7 and travelling belt 5; Be provided with 9 patterns 4 on the described travelling belt successively; Travelling belt makes the front of travelling belt 5 show 0-9 pattern respectively through the cooperation scrolling realization CW or the anticlockwise transmission of the fixed idler whell and the axis of rolling.
Claims (2)
1. mathematical education appurtenance; It is characterized in that it comprises support (2), on support, be provided with figure place direction board (1); The below of each figure place direction board is provided with 1 digit groups (3), and described digit groups is made up of the digital scraps of paper that 10 one ends are fixed on the support; The support of each digit groups below is provided with the corresponding pattern groups that is made up of fixed idler whell (6), the axis of rolling (7) and travelling belt (5); Be provided with 9 patterns (4) on the described travelling belt successively; Travelling belt makes the front of travelling belt show 0-9 pattern respectively through the cooperation scrolling realization CW or the anticlockwise transmission of the fixed idler whell and the axis of rolling.
