The numeracy abacus can help people to numerate, count and learn numbers. The numeracy abacus is beneficial to culture the autonomous learning and calculating capabilities and intelligence development of students, and is suitable for being used as teaching tools or studying tools in a grade 1 and a grade 2 and a kindergarten.
Description
Technical field
The utility model provides the knowledge that the stationery field is used to know number, calculating and teaching and intelligence development and figures dish.
Background technology
Before the utility model proposes, " Abacus of nine-bead on one shaft " last every grade of string has nine pearls, and the middle pearl look of attaching most importance to is gone up and dialled to adding, and sets aside to subtracting.
For the child and of first knowledge number and calculating, sophomoric student, existing " Abacus of nine-bead on one shaft " obscured easily because bead is many.So utilize existing abacus to carry out the teaching of child's primary grades, do not reach clear knowledge number, the effect of convenience of calculation.
Summary of the invention
In order to overcome the shortcoming that the bead that has abacus now is many, know the number difficulty.The utility model provides a kind of knowledge to figure dish.This abacus realizes knowing fast the effect of number and calculating by the number that changes pearl with putting in order.
The scheme that the utility model technical solution problem is adopted is:
Intert in the rectangle abacus frame bead bar is installed, string is with the bead of the different pearl numbers that can slide up and down on the bead bar, is provided with the mark point on the abacus frame of the upper and lower part of bead bar, bead color branch attach most importance to look bead and light bead.
The bead bar from left to right has 13, wherein goes here and there the bead number bead of corresponding bead bar quantity respectively of cover on one to ten bead bar.
The the 5th to ten and the 12 and 13 bead bar on 5 beads in top of the cover of going here and there scribble heavy look, the look bead 3.1 of attaching most importance to, other bead scribble light color, are light bead 3.2.
Mark successively in the pairing abacus frame of first to the tenth bead bar bottom with it and go here and there the identical numeral of bead number of cover.From left to right be respectively 1,2,3,4,5,6,7,8,9,10.
The mark point is " hundred " position on the abacus frame of the top of the ten a bead bar, and the mark point is " ten " position on the abacus frame on the 12 bead bar top, and the mark point is " hundred " position on the 13 bead bar top abacus frame.
Good effect, because knowing, the utility model figures dish, preceding 10 bead bars are gone here and there successively and are with 1-10 bead, and mark corresponding digital " 1-10 " respectively in the abacus frame bottom, next 3 grades upper ledge marks the mark point of " hundred, ten, individual " respectively, and five beads in top of each bead bar and the colouring discrimination setting of other bead, so can be familiar with 100 with interior number and 100 computing method derivation and letter calculations with multiplication and division in the interior plus-minus method, hundred clear and intuitively.Help fostering the students' ability to study on their own, computing power, intelligence development, suitable one, second grade and kindergarten use as teaching aid or schooling apparatus.

Use of the present utility model
1, liquidation, bead are used preceding liquidation earlier all by lower frame;
2, dial bead on by upper ledge, go up and dial to adding;
3, set aside bead from upper ledge, set aside to subtracting;
4, counting: heavy look pearl all up is 5, and heavy look pearl many 1 is 6, and many 2 is 7, and many 3 is 8, and many 4 is 9;
5, understanding number and calculating.
Purposes of the present utility model
1, understanding 100 is with interior number
(1) counts number
Position shelves on abacus the right, it is several 1 by upper ledge to dial a following pearl, dials a following pearl again and leans on upper ledge several 2, it is several 3 by upper ledge to dial a following pearl again ..., several 10 at present pearl do not had, just dial and go 9, make bead leave upper ledge, last shelves just ten shelves dial Rhizoma Trillii Tschonoskii and represent.
(2), numeration
Bead is numeration by upper ledge.Dial a last following pearl and just write down 1, dial two following pearls, represent 2 on the abacus by upper ledge by on the last frame abacus ...
Dialled 5 o'clock, and, just all heavy look pearls were up dialled directly from the 5th pearl; Dialled 6 o'clock, and can begin one from the Rhizoma Trillii Tschonoskii of heavy look pearl bottom and up dial; Dialled 7 o'clock, and can up dial from second pearl of heavy look pearl bottom ...
When dialling double figures, up dial for two grades in the back.When for example dialling " 23 ", dial 2 pearls by upper ledge at ten shelves, shelves are dialled 3 pearls by upper ledge in individual position.
(3) Shuo composition and decomposition
Study 10 composition and decomposition with interior number are carried out at preceding 10 grades; Study 100 is carried out in the back third gear with decomposition with the composition of interior number.
(4) Shuo comparison.
2, calculate
(1) plus-minus of 2-10 number calculates and carries out at preceding ten grades.For example 6 plus-minus calculates and carries out at the 6th grade, goes up and dials to adding, and sets aside to subtracting.10 calculate comprehensive exercise with interior plus-minus carries out at abacus the right individual position shelves and ten shelves.
(2) 20 with the interior carry addition and the subtraction of giving up the throne
Calculate reason and algorithm by the derivation of by-blow abacus, reach skilled brain and calculate.
