Description

M252046 IV. Creation Instructions (l) [Technical Field to which the New Type belongs] This creation relates to the improvement of the structure of the abacus, especially a type with nine abacus and divided into two colors' to make it easier to judge & The new abacus design is designed to facilitate image learning and image memory to increase learning efficiency and interest. [Previous Technology] The abacus is a traditional and long-established computing tool used in China, and it has been transmitted to neighboring countries such as Japan, South Korea, and Southeast Asia, which has a profound impact. And the abacus design of the traditional abacus is usually a string of five. The upper one is separated from the lower four. The upper one represents "five", and the lower one represents "one." There are two abacus with four under it. No matter what kind of abacus, beginners_ must recite the formula and be familiar with the technique of moving the abacus before they can use the abacus to solve mathematical problems such as addition, subtraction, multiplication, and division. For this reason, many teachers are teaching, Have to make every effort to explain the meaning of the "five" of beads, and ask students to memorize the gaps in order to facilitate the use of calculations. If parents want to teach students to use the abacus, or the students themselves to explore, there is a certain degree of difficulty. Moreover, the current elementary school advocates constructive mathematics, and students are no longer encouraged to learn mathematics by reciting memory. The recitation formula has been regarded as a negative teaching guide to suppress the thinking ability of school children. Based on this, a decimal abacus was designed, such as the new patent case (hereinafter referred to as the former case) of the Republic of China Patent Gazette Announcement No. 5 3 2009 “Teaching Tools for Compound Number, Quantity and Graphic Training” The former case is characterized in that each string of beads is formed by a string of nine abacus, each

P93017.ptd Page 5 M252046 4. Creation instructions (2) The number represents one, of which the fifth is distinguished by a color different from the other eight abacus, because there is no traditional abacus in the previous case. The problem of getting round. When students use the abacus in the previous case to learn mathematics, they can use the intuitive decimal algorithm to dial the abacus counting. Instead of reciting the formula, using this abacus to learn mathematics has broken away from the traditional recitation, and then use image learning or Image memory method to improve the mathematical understanding of school children. However, the abacus in the previous case, excluding the traditional abacus with an independent interval representing the number of "five" abacus, is a string of nine abacus. Although the color is separated on the basis of use, each string of beads is too long. In fact, it is not good for the learning of image memory, and it is easy for the numbers "eight" and "seven", "four" and "three" to be confused. In view of the shortcomings of the above-mentioned custom abacus and the previous case, the author researched and designed the above-mentioned shortcomings thoroughly, and after many experiments and improvements, this creation finally came into being. [Purpose of this creation] The main purpose of this creation is to provide a new type of abacus design that is easier to interpret when performing calculations, in order to facilitate image learning and image memory, thereby increasing learning efficiency and interest. [New content] This is a structural improvement of a decimal abacus, which is provided with "5" number marks on the left and right sides of a frame to increase the memory of the number during calculation, and in the frame There are several shafts, each of which has nine abacus strings, each abacus represents the number "one", the upper five beads are a group, the lower four are a group, there are two groups in total, two groups Abacus

Creation Instructions (4) — ^ ~: Each adjacent five abacus (3) is a group, the next group, the lower four are the first group, and the two groups are different No. = four is the first. In addition to the difference between the available abacus (3) & placement, it is more profitable: 2 divisions, and numbers, fast and convenient. Shoulder reading

During implementation, two, three, four, and five colors of the two groups can be yellow, and the first, fourth, seventh, and the frame (1) at the intersection of the frame base can be used to distinguish the single, thousands, As shown in the third to sixth figures, this figure is divided into five beads (3) as the number "one", one on the upper bead is five, and the decomposition and combination of calculus 5 That is, 1 and 2 are 5, and 4 and 1 are 5, and the number of "5" is played. Dial the upper and lower yellow, dial the upper yellow and the red. The abacus must recite the formula to calculate an abacus to represent the number "5". Can be equal. Therefore, the original use is very structured on the theoretical basis, and can solve the disturbance of the 5 "learning, the national elementary school mathematics teaching is decimally located in the traditional abacus and previous case design. , Seven, eight, and nine are red: Ten, thirteen rows of shafts (2) and frames are each provided with a marking point (4) for digits, billions of digits, and megabits. The creation is based on the abacus of the same color (3, the lower group is four, and each of the five abacus is a traditional abacus. When the above group of colors is used, 4 is 5, 2 and 3 are 5, For example, if you dial the yellow set above, you can color and red. The two sets are "9" and the number is "6", which breaks away from the traditional puzzles, because the traditional abacus causes inconvenience in mathematics and numbers and is easy to practice. Memories can also determine a bead on the traditional abacus ^ as its biggest feature, and combine with the teaching of the current system, and there is only the position of the abacus (3)
