Abstract

The utility model discloses a color lump type arithmetic teaching aid, comprising color lumps (1). Ten color lumps with the same color form a group. Various groups of the color lumps (1) have different colors. A connecting rod (2) passes through the center of the side face of each color lump (1) and has a required graphic profile. The connecting rod (2) is provided with two or more than two groups of color lumps (1). The teaching aid is vivid and visual, can effectively improve the impression of students so that the students can quickly learn and grasp the arithmetical elementary knowledge in a short period of contacting. The teaching aid is good in expansibility, and also can be used as an article such as a toy or a decorative article, etc. Furthermore, the teaching aid also has the advantages of simple structure, low cost, durability, elegant appearance, etc.

Description

Color block type arithmetic teaching tool

Technical field

The utility model relates to a kind of teaching aid, especially color block type arithmetic teaching tool.

Background technology

At present, the teaching aid of school is the expression directly perceived of student's learning knowledge, and the numeral expression of abstract is transformed in the middle of the material object, improves perceptual knowledge, increases student's influence.But present educational aid can only be used as the classroom usually, student to Long contact time, feel dry as dust easily, and shortage extendability, can only lack intention on the profile as single teaching aid, on the method that helps the student to understand and remember, also be difficult for causing students'interest in learning, and the production cost height of general teaching aid, damage easily.

The utility model content:

The purpose of this utility model is: a kind of color block type arithmetic teaching tool is provided, and its using method is easily understood, and teaching aid is vivid, favorable expandability, with low cost, to overcome the deficiencies in the prior art.

The utility model is achieved in that color block type arithmetic teaching tool, it comprises color lump, and the color lump of 10 same colors constitutes 1 group, and the color of every group of color lump is all inequality, a connecting link is passed at the center, side of each color lump, and connecting link is needed graph outline; 2 groups or 2 groups of above color lumps are arranged on the connecting link.

Being more preferably color lump is rectangle, triangle, rhombus or circular block.

Can also allow the connecting link be Metallic rod, rod, plastic bar or cotton thread.

Owing to adopted technique scheme, compared with prior art, teaching aid of the present utility model vivid can effectively be improved student's impression, makes them can be in the contact of short time, and very fast study also grasps the ABC of arithmetic.The favorable expandability of product of the present utility model can also be as article such as toy, decorations, and product itself also has advantages such as simple in structure, with low cost, not fragile, elegant in appearance.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment

Embodiment 1 of the present utility model: the structure of color block type arithmetic teaching tool as shown in Figure 1, color lump 1 by 10 same colors constitutes 1 group, color lump 1 is that the color of every group of color lump 1 of rectangle bulk (also can be triangle, rhombus or circle etc.) is all inequality, the connecting link 2 of a steel wire system is passed at the center, side of each color lump 1, and connecting link 2 is bent to graph outline shown in Figure 1; 4 groups of color lumps 1 (shape of every group of color lump 1 can be identical with size, also can be different) are arranged on the connecting link 2; Wherein same group

On each face of color lump 1 mutually different color is arranged all, all colours on the color lump 1 on the same group is all not inequality.

When using, calculate according to the pithy formula of making up the number or amount on basis, for example:

When calculate 3 and 8 and the time, the color lump 1 that to represent units is earlier dug 3 and is used for representing 3, and at this moment, the color lump 1 of remaining expression units does not have only 7, can not dig 8 and represent 8, need mend 2 according to the pithy formula of making up the number or amount this time so, just advance one during the addition complement, dig the color lump 1 of 1 expression tens, color lump 1 original position of overturning back with 2 expression unitss, the color lump 1 of representing tens so has 1, and the color lump 1 of expression units has 1, has just represented result 11.

In the time of the difference of calculating 16 and 7, the color lump 1 that to represent tens is earlier dug 1 and is used for representing 10, the color lump 1 of expression units is dug 6 be used for representing 6, the numeral that represent on the teaching aid this moment is exactly 16, when calculating deducts 7 because 7 of color lump 1 deficiencies of the units dug, therefore to give up the throne at ten, according to the complement pithy formula, 7 move back 1 mends 3, the color lump 1 that just will represent tens turns back 1, to represent that simultaneously the color lump 1 of units digs 3 again, have 9 at the color lump 1 one of expression units and dig this moment, and the result is exactly 9;

When calculate 3 and 4 long-pending the time, what need at this moment that the student remembers is multiplication formula table, 3 and 4 multiplication pithy formula, the result is 12, just is presented as on teaching aid that so the color lump 1 of representing tens digs 1, represents that the color lump 1 of units is dug 2.

In the time of the merchant that calculates 24 and 6, utilization in this time quotient pithy formula obtains result 4, on teaching aid the color lump 1 of tens is given up the throne fully, and soon the color lump 1 of tens all turns back, and making color lump 1 quantity of units then is 4, obtains result 4.

In this way, the student can see the result intuitively, understood process again, increased the memory impression, results of learning have been improved, simultaneously again because connecting link 2 has formed the profile of a pattern, color lump 1 is distributed on the connecting link 2, can also express the pattern of different colours by on the same group color lump 1 not, and can allow and mutually different color is arranged on each face of color lump 1 of same group, can change the color of pattern by upset color lump 1, make the whole pattern content changing,, can effectively attract student's interest as student's a kind of toy or ornament, to learn and the amusement combination, fully improve results of learning.And the color lump 1 of product can adopt nontoxic plastics to make, and safety is light and handy, and production cost is low, and is durable again; The connecting link 2 of product can be selected Metallic rod for use, improves intensity, durable again, can also adopt rod, and is light and handy, cheap, also can adopt plastic bar, various shapes, not water funk; In needs product softness, also can adopt cotton thread to be used as connecting link 2.

Claims (3)

1. color block type arithmetic teaching tool, it is characterized in that: it is made up of color lump (1) and connecting link (2), the color lump of per 10 same color layers (1) constitutes 1 group, and each color lump (1) all is connected on the connecting link (2), is connected with the color lump (1) more than 2 groups or 2 groups on connecting link (2).

2. color block type arithmetic teaching tool according to claim 1 is characterized in that: color lump (1) is rectangle, triangle, rhombus or circular block.

3. color block type arithmetic teaching tool according to claim 1 is characterized in that: connecting link (2) is Metallic rod, rod, plastic bar or cotton thread.
