Abstract
The utility model discloses a picture type mental calculation teaching aid. 10 boxes of which the surfaces have stars and the star number is increased from 1 to 10 form one group of teaching aids. A push-pull inner box is respectively arranged in the boxes with the star number from 1 to 9, and the inner box is provided with stars of which the number is the same with that of the outer box. The stars have the sequence that stars with the number from 1 to 5 are inside arranged into one row; for the starts with the number from 6 to 10, the upper row has 5 stars, and the lower row has 1 to 5 stars. The utility model can guide the metal calculation in a visual and interesting way, enables the children to transfer to the mathematic oral calculation or conditional reflex oral calculation on the basis of looking picture, and is especially suitable for training the calculation of infants or children.
Description
Technical field
The utility model relates to a kind of schooling apparatus, specifically is a kind of graphic 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, 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 not suitable for the study of children below six years old, the chess mental arithmetic realizes that brain calculates very shortcomings such as difficulty, and therefore, learning above algorithm all needs Faculty and Students' energy and time that costs a lot of money on class hour and training burden, study is got up harder, and effect is also undesirable.
The utility model content
Technical problem to be solved in the utility model provides that a kind of student of allowing easily learns, graphic mental arithmetic teaching tool easy to learn.
The utility model solves the problems of the technologies described above with following technical scheme: the graphic mental arithmetic teaching tool of the utility model is to constitute one group of teaching tool by 10 appearances by the arrange box of star of 1 to 10 quantity, but wherein be provided with the inner box that is respectively equipped with a push-and-pull in the box of 1 to 9 star, the inner box surface is provided with and the identical star of outer box quantity.
The ordering of described star is: be arranged in a row in 1 to 5,6 to 10 by 5 of last rows, 1 to 5 of following row.
The graphic mental arithmetic teaching tool of the utility model 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 on basis with the aid of pictures, carry out the transition to mathematics mental arithmetic or conditioned reflex mental arithmetic, 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.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
The graphic mental arithmetic teaching tool of the utility model is to constitute one group of teaching tool by the box 1 that 10 appearances are equipped with star 3, the quantity of star 3 is arranged in respectively on 10 boxes by 1 to 10, but wherein be provided with the inner box 2 that is respectively equipped with a push-and-pull in the box 1 of 1 to 9 star, the inner box surface is provided with the star 3 identical with outer box quantity.
The ordering of described star is: be arranged in a row in 1 to 5,6 to 10 by 5 of last rows, 1 to 5 of following row.
The method of operating of the graphic mental arithmetic teaching tool of the utility model has following several:
1) when needs are demonstrated the additive operation of two numbers, there is the box of respective numbers star to make up with two, just see operation result intuitively.For example:
1+2: have the box of 2 stars to make up a box that 1 star arranged and one, have 3 stars on two boxes, the result equals 3.
5+3: have the box of 3 stars to make up a box that 5 stars are arranged and one, form 5 times 3 combination, the result equals 8.
8+2: have the box of 2 stars to make up a box that 8 stars are arranged and one, 8 gather into 10 with 2, and the result equals 10.
6+7: have the box of 7 stars to make up a box that 6 stars are arranged and one, two groups of stars that earlier will be top form 10, calculate 1 the following star and the combination of 2 stars again, and the result equals 13 after the addition.
2) when running into two identical number additions, get the box of respective numbers star and pull out inner box and demonstrate the star identical with outer box, just finish to quicklook result of calculation.For example:
2+2: find out the box of 2 stars, pull out inner box again from this box, just can see and calculate the result intuitively is 4.
3) when needs are demonstrated the subtraction of two numbers, taking out one has the box of respective numbers star or is combined into by two boxes and have respective numbers star, utilizes covering method or mental arithmetic just to finish result of calculation then.For example:
4-3: with a box that 4 stars are arranged, mental arithmetic deducts 3 stars, and the result equals 1.
8-6: with a box that 8 stars are arranged, mental arithmetic deducts 6 stars (deduct 5 times 1 form 6), and the result equals 2.
11-9: box and 1 star by 10 stars is formed 11, again with 10 star mental arithmetics deduct 9 (deduct last form for 5 times 4 9) 1, and then and 1 star combination, the result equals 2.
Claims (2)
1. graphic mental arithmetic teaching tool, it is characterized in that: every group of teaching tool is made of by the arrange box of star of 1 to 10 quantity 10 appearances, but wherein be provided with the inner box that is respectively equipped with a push-and-pull in the box of 1 to 9 star, the inner box surface is provided with and the identical star of outer box quantity.
2. graphic mental arithmetic teaching tool according to claim 1 is characterized in that: the ordering of described star is: be arranged in a row in 1 to 5,6 to 10 by 5 of last rows, 1 to 5 of following row.
