Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1, this embodiment provides a child color bead calculator, including 13 gears vertically disposed in a housing cavity of a frame 1. Nine beads 3 are arranged on each gear lever in a penetrating manner in the first twelve gears, ten beads are arranged on a gear lever in a tenth gear in a penetrating manner, one additional bead 3.4 is arranged more than other gears, and a special number marking point '10' is arranged on a lower beam of a frame body corresponding to the gear; the upper four of the nine beads are upper beads 3.2, the middle one is a middle bead 3.1, and the lower four are lower beads 3.3; the upper abacus beads are respectively provided with a first color, a second color, a third color and a fourth color from top to bottom, such as black, blue, green and yellow; the lower abacus beads also have a first color, a second color, a third color and a fourth color from top to bottom, such as black, blue, green and yellow; the Chinese abacus beads and the additional beads are red. The frame upper beam corresponding to the eighth gear, the ninth gear, the tenth gear and the eleventh gear is provided with a digital marking point 4: "thousand", "hundred", "ten" and "several".

Taking the color of the beads as an example, the characteristics of the children colored bead calculator disclosed by the application are described:

1) The upper dialing is added, and the lower dialing is subtracted; the addition and subtraction within 9 adopts straight addition and straight subtraction, and overcomes the abacus calculation difficulty of 'full acanthopanax' and 'broken five subtraction' of the traditional abacus.

2) The 1 st bead of each gear is a black bead, which is called 1 black; the 2 nd beads are blue beads, which are called '2 blue'; the 3 rd beads are all green beads, which are called as 3 green; the 4 th beads are all yellow beads, which are called as '4 yellow'; the 5 th beads are all red beads, which are called as '5 red'; the sixth beads are all black beads, which are called "red-black 6"; the 7 th beads are blue beads, which are called 'red blue 7'; the 8 th beads are all green beads, which are called as 'red green 8'; the 9 th beads are all yellow beads, which are called as 'red-yellow 9'; the 10 th bead of the 13 th grade is a red bead, which is called as 'red 10'. When reading or calculating, one number of beads are not needed, and the corresponding number is known only by memorizing the color of the last bead of each number, so that the method is clear at a glance.

3) As shown in fig. 2, the last color bead of any one grade is shown, and the front grade is seen leftwards, so that the number is decomposed into several and several; looking to the right at the next few steps, it is known that this number is a few from the other numbers. By utilizing the characteristic, left view is minus and right view is plus. Addition and subtraction within 10 can be performed without finger movement, so that the user can understand the learning process at a glance, which is incomparable with other computing tools.

4) The addition of several strains and the reduction of several strains can be presented on the calculation aid one by one. And when the number of the simple bead dialing skills is large, the corresponding addend or the subtrahend can be known only by remembering the bead arrangement sequence, and the bead dialing can be completed once in each step of calculation. As shown in FIG. 3, the two beads of the same color are all 6, namely "double blue" on 1+6, "double green" on 2+6, and "double yellow" on 3+6. According to the special ordering rule of the color beads, it can be seen that: one bead is left for two same-color beads, namely 5, one bead is left for two same-color beads, namely 7, and two beads are left for two different plants, namely 8.

5) And finally, ten calculation beads are arranged at the first gear, so that the teaching difficulty of carrying addition and withdrawal reduction is solved. As shown in fig. 4: the last gear is arbitrarily shifted by one number, and the other complement number added with the last gear to obtain 10 is known. The algorithm of carry addition and abacus can be well understood by utilizing the unique characteristics of the method.

6) The frame bodies of the 8 th gear, the 9 th gear, the 10 th gear and the 11 th gear are Liang Biao provided with thousands, hundreds, tens and thousands, and the upper frames of the two last gears have no digital mark points. The two-gear multiplication pithy formula can be fully utilized. Firstly, the same addend is dialed out on the left side of the abacus; the right hand carries out the same number of times in the last two gears and the left hand dials out the times of addition in the unit gears. The multipliers, the multipliers and the products are all presented on the abacus one by one while being added. On the basis of fully understanding the theory, the pithy formula is said while the beads are dialed.

7) And (3) by utilizing the characteristic that the last two gears have no digit marking points, learning the division calculation of dividing the multi-digit number by the one-digit number. The divisor is firstly dialed on the right side of the abacus, and the divisor is dialed on the left side of the abacus. From the high position, comparing the divisor with the divisor, and setting the divisor with a large number (or the same number), and setting the quotient number with a gear; the number is small, the number of the shift-adjacent shifting quotients is small, and the number of the shift-adjacent accumulation reduction is small.

8) By using the digital gear of the calculation aid, the multiplication of multiplying the multi-digit by the one-digit is matched with the mathematical teaching material from the low digit. The ten-position gear and the unit gear are set aside, and the multi-position gear serving as the first multiplier is dialed on the abacus. The multiplier of one digit is dialed to the left of the abacus. Then, from the low order, the product of two numbers is dialed in the last two digits, which digit is multiplied, which digit multiplier is dialed; multiplying the previous bit; after multiplication, the product is completely displayed on the corresponding digit.

9) When calculating, the color of the last calculation bead in each step is remembered, and the corresponding number looking beads or the auditory beads can be calculated. For example: 3+2 remembers "5 red", 5+2 remembers "red blue 7", and 7+2 remembers "red yellow 9". The color bead calculator perfectly shows the function of 'bead dynamic number out', and long-time special training of the bead translation number or the number translation strain is not needed.
