Natural number four-digit four-level composite number-level reading demonstrator

Abstract

The utility model discloses a natural number four-digit four-level composite number level reading demonstrator, relates to the field of middle and primary school mathematics teaching, teaching research and calculator manufacturing and application, and aims to apply a natural number four-digit four-level grouping method to group natural numbers according to natural number single number levels and composite number levels and read and write numbers according to the natural number four-digit four-level grouping reading method. The theory and method problems of disordered reading of natural numbersin the teaching and application process are solved,a natural number four-digit four-level composite number level reading demonstrator is characterized by being composed of a bottom plate (1), a digital voice integrated circuit board (2) and a cover plate (3). A bottom plate (1), a digital voice integrated circuit board (2) and a cover plate (3) are sequentially and horizontally placed on a horizontal tabletop from bottom to top and are fixed by nuts with caps through corresponding mounting round holes in four corners, during application, a method and a working principle of any natural numberreading which does not exceed 32 digits of four composite number levels are demonstrated.

Description

Technical field[0001]An invention of a four-digit four-level compound number reading demonstrator for natural numbers, involving the field of primary and secondary school mathematics teaching, research, calculator design and manufacturing, and calculation applications in various sectors and industries. It aims to solve the introduction of Arabic numerals from the West to my country Since then, there has always been a problem of random reading and writing, especially to solve the problem of random reading of calculators made with chip technology in the working state of software programs, and to avoid the adverse effects of misreading and random reading on mathematics teaching in primary and middle schools.Background technique[0002]In the production and life of the workers and peasants and all classes, there have been problems of reading natural numbers and writing natural numbers since ancient times. In the ten Arabic numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 After being introduced into ...

Problems solved by technology

[0003] However, when it comes to specific readings, almost all teachers read 10 as ten. On several 10 yuan banknotes printed and designed by the People's Bank of China, there are correct readings of "ten yuan" and incorrect readings. The pronunciation of "shiyuan" two phenomena

[0004] In ancient my country's four great classics, "The Romance of the Three Kingdoms", "Water Margin", "Journey to the West", "Dream of Red Mansions" and other novels, there are also issues related to reading. When telling the story of Wu Song fighting a tiger in "Water Margin", there is Wu Song in the "Three Bowls But Not the Hill" hotel There are two phenomena of eating eighteen bowls and eighteen bowls before and after. In "Journey to the West", Monkey King flew one hundred and eight thousand miles with one touch. Many people read it as one hundred and eight thousand miles. They think that 108,000 The 0 between the one hundred thousand digit 1 and the thousand digit 8 of this natural number needs to be read, and it has been read as one hundred and eight thousand by a calculator. There is no such intuitive teaching aid of the present invention, and there is no way to present it technically. Readers and students explain the phenomenon clearly
