Abstract
The utility model discloses a graph mental arithmetic teaching tool. Each group of teaching tools is formed by ten teaching tools which are formed by the hinge joint of upper covers and lower covers. Upper cover upper plate surfaces and lower cover lower plate surfaces of nine teaching tools are provided with same stars according to the number from one to nine, only upper cover upper plate surface of the other one teaching tool is provided with ten stars, and lower cover lower plate surface of the other one teaching tool does not provided with star to represent the number of zero. Both the upper covers and the lower covers are provided with magnets. According to the graph mental arithmetic teaching tool of the utility model, mental arithmetic can be led from a visual and interesting graph, a child makes a transition to mathematical oral calculation or conditioned reflex oral calculation based on the viewing of the graph, and the graph mental arithmetic teaching tool is especially suitable for the arithmetic training of infants or children.
Description
Technical field
The utility model relates to a kind of schooling apparatus, specifically a kind of figure mental arithmetic teaching tool that is applicable to kindergarten and primary school mathematics.
Background technology
At present of a great variety about children's computing method, the methods such as abacus mental calculation, the calculation of hand brain, chess mental arithmetic are arranged, but the abacus mental calculation method is difficult to grasp, the hand brain is calculated and is conflicted mutually with mathematics number concept, computing method, and the chess mental arithmetic realizes the shortcomings such as the brain calculation is very difficult.Chinese patent application number is called " diagram type mental calculation teaching aid " preferably results of learning is played in kindergarten and primary school mathematics for " 201020153763.7 ", utility model name, but there are two drawbacks in the calculating process of this teaching tool: 1, when running into two identical number addition, need get the box of respective numbers star and pull out inner box and demonstrate with the box of outside identical star is arranged, the operating process of push-and-pull box is comparatively loaded down with trivial details, greatly affects computing velocity.2, because the structure of its teaching tool is box type, for certain limitation is arranged in the material requirements, select only the harder materials such as plastics, timber just can finish push-and-pull.Therefore Faculty and Students are at class hour and the training burden energy and time that costs a lot of money, and results of learning are not remarkable.
The utility model content
Technical problem to be solved in the utility model provides that a kind of student of allowing easily learns, figure mental arithmetic teaching tool easy to learn.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model figure mental arithmetic teaching tool, its every group of teaching tool forms by loam cake and the hinged teaching tool that consists of of lower cover by 10, wherein the loam cake upper face of 9 teaching tools all is provided with identical star by 1 to 9 quantity with the lower cover lower face, and 1 teaching tool only has the loam cake upper face to be provided with the star of 10 quantity in addition, and its lower cover lower face does not arrange star and represents that quantity is 0; Loam cake and the lower cover of each teaching tool are equipped with magnet.
The ordering of described star is: be arranged in a row in 1 to 5, wherein 1 to 4 comes the cover plate bottom, and two rows are lined up in 6 to 10 in 5 tops that come cover plate, 5 of cover plate top rows, and the bottom is by 1 to 5 row.
The utility model figure mental arithmetic teaching tool meets the operation law of the addition subtraction multiplication and division of the cognitive level of child's logarithm and primary school mathematics, can draw mental arithmetic from interesting figure directly perceived, make children be transitioned into mathematics mental arithmetic or conditioned reflex mental arithmetic on basis with the aid of pictures, the reflection that does not need to remember figure after skilled just can calculate, and is specially adapted to child or children's calculation training.

Among the figure: loam cake 1, lower cover 2, loose-leaf 3, star 4, magnetic operator plate 5.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
Every group of teaching tool forms by loam cake 1 and the lower cover 2 hinged teaching tools that consist of by 10, loam cake 1 forms by parts such as loose-leaf 3 or bearing pins with lower cover 2 and is flexibly connected, loam cake 1 or lower cover 2 can be around the other side's Rotate 180 degree, there is the loam cake upper face of 9 teaching tools all by 1 to 9 quantity identical star to be set with the lower cover lower face in every group of teaching tool, and 1 teaching tool only has the loam cake upper face to be provided with the star 4 of 10 quantity in addition, and its lower cover lower face does not arrange star and represents that quantity is 0.The inboard of loam cake and lower cover is equipped with magnet, make both mutual magnetic, and lower cover can be inhaled mutually with magnetic operator plate 5.
The above-mentioned star ordering that is arranged in loam cake or lower cover is: be arranged in a row in 1 to 5, wherein 1 to 4 comes the cover plate bottom, and two rows are lined up in 6 to 10 in 5 tops that come cover plate, 5 of cover plate top rows, and the bottom is by 1 to 5 row.
When using the utility model to practise operating, when not needing to open teaching tool, be lower face with lower cover 2 by magnet pasting on magnetic operator plate 5, as shown in Figure 3; When needs are opened lower cover and are operated, lower cover opened the Rotate 180 degree after, the same lateral plates that again loam cake and loam cake is had magnet places on the magnetic operator plate 5, like this, in operating process, the utility model teaching tool just is difficult for being dropped.
The method of operating of the utility model figure mental arithmetic teaching tool has following several:
1) when needs are demonstrated the additive operation of two numbers, there is the teaching tool of corresponding star quantity to make up two of unfolding, just see intuitively operation result.For example:
0+1: the lower cover lower face is not had the teaching tool one side of star and has the teaching tool of 1 star simultaneously to make up, have 1 star on two teaching tools, the result equals 1.
1+2: the teaching tool one side of 1 star will be arranged and have the teaching tool of 2 stars simultaneously to make up, and have 3 stars on two teaching tools, the result equals 3.
5+3: the teaching tool one side of 5 stars will be arranged and have the teaching tool of 3 stars simultaneously to make up, and form 5 times 3 combination, the result equals 8.
8+2: the teaching tool one side of 8 stars will be arranged and have the teaching tool of 2 stars simultaneously to make up, 8 gather into 10 with 2, and the result equals 10.
6+7: the teaching tool one side of 6 stars will be arranged and have the teaching tool of 7 stars simultaneously to make up, first two groups of top stars be formed 10,1 star below calculating again and the combination of 2 stars, the result equals 13 after the addition.
2) when running into two identical number addition, after opening, the teaching tool of getting corresponding star quantity sees just that the lower face of the upper face of loam cake and lower cover demonstrates the star of equal number, just finishes to quicklook result of calculation.For example:
2+2: find out the teaching tool of 2 stars, the lower cover upset is opened, just can see intuitively and calculate the result is 4.
3) when needs are demonstrated the subtraction of two numbers, taking out one has the teaching tool of respective numbers star or is combined into by two teaching tools and have respective numbers star, then utilizes covering method or mental arithmetic just to finish result of calculation.For example:
1-0: with a teaching tool that 1 star is arranged, mental arithmetic deducts 0 star, and the result equals 1.
4-3: with a teaching tool that 4 stars are arranged, mental arithmetic deducts 3 stars, and the result equals 1.
8-6: with a teaching tool that 8 stars are arranged, mental arithmetic deducts 6 stars (deduct 5 times 1 form 6), and the result equals 2.
11-9: will form 11 by teaching tool and 1 star of 10 stars, again with 10 star mental arithmetics deduct 9(deduct upper form for 5 times 4 9) 1, and then and 1 star pattern, the result equals 2.
