Description
Technical field
This utility model is related to teaching field, more particularly, to a kind of multifunction demonstrator.
Background technology
In the teaching of primary school mathematics, as the age of student is less, compare dislike to uninteresting numeral and contradict, on the contrary
It is in kind to the colorful one especially interested, therefore the suitable mathematics teaching aid of making can give huge help to student learning.
Utility model content
Based on problem present in primary school math teaching, the purpose of this utility model is to provide a kind of Multifunctional demonstration
Device.
The purpose of this utility model is mainly by following technical scheme realizing.
A kind of multifunction demonstrator, which includes：Inner ring, Long pointer, short pointer, centre circle, centre circle disk, outer ring, outer ring half
Disk, Fructus Persicae lamination and support, the inner ring are circle, are uniformly divided into four sector portions, and each section coats different colors
And different toys are drawn, to show differentiation, and each two sector portion junction has one near the part of circle camber line
Little sector, marks upper " all directions " four direction respectively, and color is different, two ends of the Long pointer and short pointer
Head is arranged on the center of inner ring, and the centre circle is circular configuration, and inner ring is with one heart, and size is more than inner ring, and inner ring coats difference
Color, the centre circle disk is uniformly installed in the outside of centre circle, prominent centre circle small semicircle, and is labeled with the face different with centre circle
1～12,12 different numerals are labeled with color, and centre circle disk, the outer ring is circular configuration, and centre circle is with one heart, chi
Very little to coat the colors different with inner ring and centre circle more than centre circle, the outer ring semi-disc and outer ring are structure as a whole, are uniformly distributed
On the outside of outer ring, prominent outer ring semicircle coats the colors different with outer ring, and the Fructus Persicae lamination is arranged in the semi-disc of outer ring
The heart, is smaller in size than outer ring semi-disc, indicates 0～11,12 different numerals thereon, and coats and outer ring and outer ring semi-disc
Different colors, the support are arranged on the center of inner ring, centre circle and outer ring, for supporting whole demonstration device.
During use, four kinds of occupation modes are had.
The first：The cognition in direction, first adjusts demonstration device, makes northern on just.Introduce to children first, in map
Orientation is that up north and down south, left west and right east, after this four direction determines, allow student to try to find northeast, and the southeast, northwest are southwestern,
And specially four toys have been drawn in this four regions, to improve the interest of child's study.
Second：The understanding of clock and watch, makes the numeral 12 on centre circle on just, introduces to children first, on clock face
12 digital, and the different implications that the different pointer of two length is represented, and Long pointer is minute hand, and short pointer is hour hands, Jiao Shizhuan
Dynamic pointer, student say the time of pointer indication, it is also possible to which teacher says the time, and student is adjusting pointer.
The third：Specific disk, inner ring, centre circle or outer ring are specified in the understanding of probability, teacher, allow student to say possibility
The size of property.Such as：Outer ring is seen in teacher's requirement, allows student to judge, Long pointer points to the probability of prime number and closes the probability of number
EquallyEtc..
4th kind：Use as mental arithmetic card：For centre circle and outer ring, outer ring numeral is rotated, teacher says operative symbol, learns
Life is done a sum orally out the result of correspondence set of number on minute hand indication centre circle and outer ring, for improve child to the adding, subtract, taking advantage of of integer,
Except the training of mental arithmetic ability.
Preferably, the Long pointer, short pointer, inner ring, centre circle and outer ring put in order for vertical, and can
Around center rotating, and can lock.
Preferably, the length of the Long pointer and short pointer arrives separately at centre circle and inner ring.
Preferably, the support is made up of three poles, can be launched and be merged, be triangularly arranged after expansion, makes to drill
Show that device is at an angle with vertical.
Compared with prior art, a kind of beneficial effect of multifunction demonstrator of the present utility model is：
By the structure composition and working method of the multifunction demonstrator, student learning interest can be effectively improved,
From the cognition in direction, the understanding of clock and watch, the many-side such as the judgement of probability and the mental arithmetic ability of integer addition subtraction multiplication and division are entered to student
Row teaching, substantially increases teaching efficiency, and visual pattern is convenient and practical, vdiverse in function, and effect substantially, and makes simple, cost
It is cheap.
