Description
Technical field
The utility model relates to a kind of educational aid, is specifically related to the primary school teaching abacus that a kind of temperature is adjustable.
Background technology
Abacus is the computational tool of Chinese tradition.Chinese invent on the basis of Long-Time Service contingrod, are important inventions of ancient Chinese, occur at arabic numeral the computational tool that Qian Shi world abacus widely uses.About the origin of abacus, can 600 BC be traced back to the earliest, it is said that China had just had " calculating plate " at that time.Ancients conspire to create one group 10 beads, and one group of group arranges, and puts into frame, then stir rapidly bead and calculate.
In ancient times, people calculate with small wooden, and these small woodens are " contingrod ", and the calculating carried out as instrument with contingrod is " calculating ".Afterwards, along with the development of producing, carried out calculating with small wooden and be restricted, so people have invented again more advanced computational tool--abacus.Arrived the Ming Dynasty, rechoning by the abacus not only can carry out the computing of addition subtraction multiplication and division, can also calculate the size of land area and various shape thing.
The one that China uses calculates apparatus, so far the history of existing more than 2600 year.Abacus is rectangle, is embedded with thin bar in wooden frame, and on bar, string has abacus bead, and abacus bead can be stirred up and down along thin bar, completes arithmetical operation by stirring abacus bead with hand.
When abacus is primary school teaching, student often needs a kind of educational aid used, but existing abacus function ratio is more single, especially to winter, has used abacus pupil to grow the hand time on abacus of beating all somewhat cold.
At present, the adjustable primary school teaching abacus of a kind of temperature easy to use is lacked.
