Abstract
The utility model relates to an it is practical in the equipment of primary school's mathematical education, concretely relates to vertical abacus teaching appearance. This vertical abacus teaching appearance's design sets up three rows of beads in rectangular frame, every row of bead sets up four, and the branch maybe the unit, ten, hundred, four column number position boards of kilobit, whenever lists 10 string beads, and at the 1st row of hollow cylinder on the preceding end device axle sleeve with the 2nd row, hollow cylinder's side surface trisection draws respectively and adds, subtracts, takes advantage of the operational sign, and crosspiece between the 2nd row and the 3rd row is made and is added slightly pair full lines and express the equal sign.
Description
Technical field
The utility model relates to a kind of equipment being practically applicable to primary school math teaching, is specifically related to a kind of vertical abacus teaching appliance.
Background technology
The teaching aid of this respect is not also had with the vertical plus-minus multiplication of visual pattern instrument teaching mathematics etc.
Utility model content
In order to the visual pattern ground problems such as the vertical plus-minus multiplication of mathematics of imparting knowledge to students, the utility model provides a kind of vertical abacus teaching appliance.The design of this vertical abacus teaching appliance is in rectangular frame, arrange three row's beads, often arrange bead and four row are set, a position, ten, hundred, kilobit four row Digitizing plate respectively, often row upper string bead 10, at the 1st row and the 2nd fore device arranged axle sleeve hollow cylinder, the side surface trisection of hollow cylinder drawing respectively adds, subtract, multiplication symbol, and the crosspiece between the 2nd row and the 3rd arranges is made overstriking double solid line and represented equal sign, as shown in the figure.Be example with additive, the 1st row is for summand, and the 2nd row is addend, the 3rd row for and, the add character of hollow cylinder turns existing.The beneficial effects of the utility model are, the vertical plus-minus multiplication of visual pattern ground teaching mathematics, structure is simple, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the structural representation of vertical abacus teaching appliance:
Wherein 1 is rectangular frame, and 2 is figure place plates, and 3 is beads, and 4 is hollow cylinders, and 5 is equal sign lines.
Embodiment
In Fig. 1, this vertical abacus teaching appliance makes rectangular frame (1) with material, three row's beads (3) are set in rectangular frame (1), often arrange bead (3) and four row are set, a position, ten, hundred, kilobit four row Digitizing plate (2) respectively, often row go here and there bead (3) 10, the 1st row and the 2nd fore device arranged axle sleeve hollow cylinder (4), the side surface trisection of hollow cylinder (4) drawing respectively adds, subtract, multiplication symbol, crosspiece between 2nd row and the 3rd arranges is made overstriking double solid line and is represented equal sign (5), as shown in the figure.During teaching, be example with additive, the 1st row of vertical abacus teaching appliance is for summand, and the 2nd row is addend, the 3rd row for and, the add character of hollow cylinder (4) turns existing.Filling it up with 10 the 3rd row ten when individual position is pull out 1 bead (3); Directly pull out bead (3) when individual position adds discontented 10 in a 3rd row position, finally on the 3rd row, directly read to obtain answer.
Claims (1)
1. a vertical abacus teaching appliance, it is characterized in that: be make rectangular frame (1) with material, three row's beads (3) are set in rectangular frame (1), often arrange bead (3) and four row are set, a position, ten, hundred, kilobit four row Digitizing plate (2) respectively, often row go here and there bead (3) 10, the 1st row and the 2nd fore device arranged axle sleeve hollow cylinder (4), the side surface trisection of hollow cylinder (4) drawing respectively adds, subtract, multiplication symbol, and the crosspiece between the 2nd row and the 3rd arranges is made overstriking double solid line and represented equal sign (5).
