Technical field
The present invention relates to teaching equipment field, be specifically related to a kind of initial mathematics coordinatometer being suitable for child and children.
Background technology
Commercially there is the professional tool that some rudimentary maths initiations are educated and learnt at present, but this kind of instrument is not also suitable for child and children, child and children are when accepting the formative education of mathematics, the way that the head of a family generally adopts spanner to refer to teaches it to carry out simple plus and minus calculation, this method has limitation, the plus and minus calculation within 10 can only be completed, and not very convenient.Therefore, be necessary to improve prior art.
Summary of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, provides a kind of initial mathematics coordinatometer that child and children can be helped to grasp basic mathematical computing fast.
The technical solution used in the present invention is: a kind of initial mathematics coordinatometer, comprises chi body, and chi body is provided with scale mark, near all or part of scale mark, mark scale value, scale value is the numeral of increasing or decreasing, and chi body is installed on vernier, vernier can slide along chi body, points to scale mark.Vernier device can select prior art, as slidingtype, magnetic force adsorption type etc.
By such scheme, scale value is the scale mark of its correspondence of multiple of 10, is longer than or is coarser than the scale mark that other scale values are corresponding.
By such scheme, described scale value scope is 0 ~ 20.
By such scheme, described scale value scope is-20 ~ 20.
By such scheme, described vernier has two.
By such scheme, described vernier rectangular triangle or fan-shaped.
By such scheme, install magnetic at scale mark place, vernier adopts or installs ferrous material, or installs ferrous material at scale mark place, and magnetic installed by vernier, or opposite polarity magnetic installed respectively by scale mark place and vernier.
By such scheme, vernier arranges projection, be provided with the pit matched with projection at scale mark place.
By such scheme, described chi body is elongated.
By such scheme, described chi body is also provided with master scale.
The invention has the beneficial effects as follows: the best instrument inherently reflecting digital rule, child and children can be allowed from the essence counted to be familiar with numeral, to understand numeral, understand the rule of numeral, a simple concept is had to the plus and minus calculation of numeral, plus and minus calculation and negative computing within easily can grasping 20 fast, open the door of mathematics; Structure is simple, attractive in appearance, is applicable to child and children's use, adds the learning interest of children and child, improve learning efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention one.
Fig. 2 is the structural representation of the embodiment of the present invention two.
Fig. 3 is the structural representation of the embodiment of the present invention three.
Wherein: 1, chi body; 2, the first vernier; 3, the second vernier.
Embodiment
In order to understand the present invention better, below in conjunction with the drawings and specific embodiments, further explanation is explained to the present invention.
A kind of initial mathematics coordinatometer as shown in Fig. 1 ~ Fig. 3, comprise chi body 1(chi body 1 and can be rectangle, circle, arc etc.), chi body 1 is provided with scale mark, near all or part of scale mark, mark scale value (scope of scale value can be arranged according to the stage of infant-growth), scale value is the numeral (comprising integer or decimal) of increasing or decreasing; Chi body 1 is installed on vernier, and vernier can slide along chi body, points to scale mark.
Preferably, scale value is the scale mark of its correspondence of multiple of 10, is longer than or is coarser than the scale mark that other scale values are corresponding.
Preferably, described scale value scope is 0 ~ 20.
Preferably, described scale value scope is-20 ~ 20.
Preferably, described vernier has two.
