Abstract

The invention discloses a color block type arithmetic teaching aid, comprising color blocks (1), wherein each 10 color blocks (1) of same color layer form one group, the color layers of different clock block groups (1) are different from each other, all color blocks (1) are connected integrally via connecting rods 92) and each color block (1) can rotate on the connecting rods (2). The invention adopts direct number style, having simple and easy operation, and combines the vivid image of the teaching aid, to effectively improve the impression on students, therefore, students can learn and handle the basic arithmetic knowledge in short time. The product has good expansibility, can be used as toys and ornaments and the like, and has simple structure, low cost, high durability and beautiful appearance.

Description

Color block type arithmetic teaching tool

Technical field

The present invention 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.

Summary of the invention:

The objective of the invention 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 present invention is achieved in that color block type arithmetic teaching tool, it comprises color lump (1), the color lump of per 10 same color layers (1) constitutes 1 group, the color layers of color lump (1) is all not inequality on the same group, each color lump (1) all passes through connecting link (2) and connects as one, and each color lump (1) all can be gone up rotation at connecting link (2).

Described connecting link (2) is needed graph outline; 2 groups or 2 groups of above color lumps (1) are arranged on the connecting link (2).

Wherein, on the not coplanar of every color lump (1), be provided with a kind of color layers at least, and on the not coplanar of every color lump (1), have the color difference of the color layers of two faces at least.Be more preferably, color lump (1) is rectangle, triangle, rhombus or circular blocks.

Described connecting link (2) is Metallic rod, rod, plastic bar or cotton thread.

Owing to adopted technique scheme, compared with prior art, teaching aid of the present invention has adopted the method that counts intuitively, computation process is easily understood, and is vivid, can effectively improve student's impression, make them can be in the contact of short time, very fast study also grasps the ABC of arithmetic.The favorable expandability of product of the present invention 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 invention;

Accompanying drawing 2 is a cartoon graphic structure synoptic diagram of the present invention.

Embodiment

Embodiments of the invention 1: the structure of color block type arithmetic teaching tool as shown in Figure 1, color lump 1 by 10 same color layers constitutes 1 group, color lump 1 is rectangle bulk (also can be triangle, rhombus or circle etc.), two kinds of color layers on the not coplanar of every color lump 1, and color difference in the color layers of two faces of every color lump 1, the color of the color layers of color lump 1 represented in Chinese character in the accompanying drawing on the color lump 1, each color lump 1 all connects as one by connecting link 2, and each color lump 1 all can rotate on connecting link 2; Connecting link 2 is bent to calculating figure shown in Figure 1 or cartoon figure shown in Figure 2; 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.

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.
