Abstract
The utility model discloses a kind of calculator for children, base plate and upper cover, cover plate, numerical digit is had to insert, upper cover covers on base plate, it is characterized in that base plate is provided with Arabic notation, the numeric character of base plate has fenestella in the relevant position of upper cover, fenestella is provided with cover plate, and cover plate can move, and exposes the numeric character of base plate.This calculator for children can make the carry of calculating directly perceived and vivid with process of giving up the throne, and children, by hands-on, can understand and grasp the plus-minus method calculating that carry is given up the throne very soon, form expertly computing power.
Description
Technical field
The utility model relates to a kind of children education instrument, be specifically within a kind of assisting child 100 plus-minus method calculate, be grouped into, retreat position demonstration calculator for children.
Prior art
The instrument that assisting child calculates is a lot, as finger, counting stick, counter, abacus etc.These assisting childs calculate instrument have a feature, be exactly intuitively, image.But teaching practice finds that children are when applying these instrument aided solving, only be beneficial to children to understand, be unfavorable for that children remember, therefore easily form the dependence to material object, hinder children to learn mental arithmetic fast, also have adverse effect to computing power development after children.In addition, in kindergarten, have instrument that a kind of assisting children calculates computing board, be similar to slipstick, its weak point is troublesome poeration, and numeral is easily obscured, and is also unfavorable for that children image is remembered; Also have our common electronic calculator a kind of, its substitutes children completely and calculates, and children cannot be allowed to form independently computing power.
About calculate carry and give up the throne, the method that we generally adopt is " gather ten methods ", and this abstract method of thinking is easy to be understood by children and grasp, but due to not vivid, children are not easily rapidly formed skilled numeracy skills, all can feel difficult when a lot of children calculate in advance and retreat position.
Summary of the invention
In view of this, the purpose of this utility model is to provide the calculator for children that plus-minus method within a kind of assisting child carries out being divided into composition within 10, carry is given up the throne demonstration and 100 calculates.
The technical solution of the utility model is: a kind of calculator for children, base plate and upper cover, numerical digit is had to insert, upper cover covers on base plate, wherein on base plate, be provided with Arabic notation, the numeric character of base plate has fenestella in the relevant position of upper cover, fenestella is provided with cover plate, and cover plate can move, and exposes base plate numeric character.
The numerical digit section of plugging is catch, and lower end is column, can be placed on and cover or insert in upper cover fenestella.It can be an independent setting that numerical digit is inserted, and also can set in a row, when setting in a row, quantity is corresponding with upper cover fenestella, can be 2 and arrive multiple.
Cover plate can overturn and open, also can sliding opening.
The numeric character of base plate often a line can arrange ten numeric characters, arranges ten row, totally one hundred.
Calculator for children of the present utility model has following advantage:
This calculator for children is closely linked to several, the number of single object and the overall recognition of amount and abstract numeric character, when being divided into plus-minus method calculating within composition and 100 within children use the utility model to assist 10, abstract computation process is converted into the operating process of concrete image, within making children promptly learn 100, plus-minus method calculates, and then the dependence broken away from computational tool, form independently computing power.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is numerical digit inserting structure schematic diagram of the present utility model.
In figure: symbol 1 represents base plate, symbol 2 represents upper cover, and symbol 3 represents cover plate, and symbol 4 represents numerical digit and inserts.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, Figure 2, calculator for children of the present utility model, base plate and upper cover, numerical digit is had to insert, upper cover covers on base plate, wherein on base plate, be provided with Arabic notation, the numeric character of base plate has fenestella in the relevant position of upper cover, and fenestella is provided with cover plate, cover plate can move, and exposes base plate numeric character.The numerical digit section of plugging is catch, and lower end is plug, can insert and open in the fenestella of cover plate.Every a line of numeric character of base plate arranges ten numeric characters, arranges ten row, totally one hundred.
