Abstract
The utility model discloses an Olympic math disc, which comprises an inserting disc, plug pins and hanging lines, wherein the inserting disc is a plane disc, a plurality of jacks are arranged on the surface of the inserting disc; a plurality of plug pins which are composed of pin heads and pin rods are arranged on the Olympic math disc; the pin rod is corresponding to the jack of the inserting disk; digits, letters, words, operating signs and geometrical figures are respectively arranged on the pin heads; the hanging line is a color thin line; hanging line mouths are equidistantly distributed at the periphery of the inserting disc. The utility model is designed to the aim at the training of the Olympic math, wide background is provided for solving problems, various figures used for solving various Olympic math problems are constructed, and the Olympic math disc can be changed, divided and moved. Various math relations are indicated in the various figures. The utility model is used for helping deeply analysis, ratiocinations and complex calculations. The utility model is suitable for various problems, the change is rich and flexible, a plurality of plotting programs are saved when the problems are answered, time and labor are saved, and the learning efficiency is improved.
Description
(1) technical field
The utility model is a kind of teaching demonstration apparatus that is used for the olympic math training.
(2) background technology
Mathematics has the characteristics of abstractness, if the time suitable learning aid and teaching aid are arranged in study and explanation, can make mathematics become directly perceived, lively, interesting, help the student understanding and thinking, grasp knowledge exactly, produce having deep love for to mathematics.That is to say that suitable learning aid and teaching aid can make study become easily efficient, play a multiplier role.At present in China middle and primary schools, olympic math has been subjected to general have deep love for and promoting, but does not also have special-purpose learning aid and teaching aid, and market is in space state.The pupil who has uses a kind of simple teaching aid box, and its function mainly is the key concept that helps pupil's understanding and cognition mathematics when just contacting the mathematics course, can't carry out deep thinking and calculating, more can not carry out number exercise difficult to understand.Puzzles such as some other Character-splicing toy bricks, figure building blocks, digital chess, its function does not exceed the level of simple cognition and simple computation substantially.
(3) summary of the invention
The purpose of this utility model provides a kind of olympic math dish with low cost, easy to use, it can provide the number key to exercises difficult to understand needed multiple background graphics, various mathematic signs can change on background graphics and move, and express various mathematical relations, analytical approach and course of solving questions.
The technical solution adopted in the utility model is: the olympic math dish comprises inserts dish and plug pin, inserts dish for planar disk, and a plurality of jacks are arranged on the card; Plug pin has a plurality of, is made of ailhead and nail bar, and the nail bar adapts with the jack of inserting dish, and ailhead is respectively numeral, letter, literal, sign of operation, geometric figure; It also includes hanging wire, and hanging wire is coloured fine rule, and the periphery of inserting dish has the line mouth that is equally spaced, and the thickness of line mouth and hanging wire adapts.
The utility model is to design at number training difficult to understand, and wide background is provided for solving a problem, and can construct the various figures that are used for the number key to exercises difficult to understand, and can change, cuts apart, move.In these figures, various mathematical relations be can represent, profound analysis ratiocination and complicated calculating helped to carry out.It adapts to multiple topic shape, changes to enrich flexibly, has saved a large amount of plotter programs during answer, and is time saving and energy saving, has greatly improved learning efficiency.The utility model be learning aid be again teaching aid, the learning aid size is less, the teaching aid size is bigger, but function is identical with principle.
(4) description of drawings
Fig. 1 is the structural representation of the square slotting dish of the utility model;
Fig. 2 is the circular structural representation of inserting dish of the utility model;
Fig. 3 inserts the structural representation of dish for the utility model hexagon;
Fig. 4 is the structural representation that the utility model gauze shape is inserted dish;
Fig. 5 is the structural representation of the utility model plug pin ailhead.
(5) embodiment
Slotting dish of the present utility model has square plate, disk, hexagon dish and four kinds of forms of yarn mesh-covered tray.The front that square is inserted dish is divided into a plurality of five equilibrium grids, on the center of grid and angle point jack is arranged.Circular front of inserting dish is divided into a plurality of equally spaced concentric circless, on each circle a plurality of one all equally distributed jacks is arranged; One all equally distributed jacks are also arranged between adjacent concentric circles.The front that regular hexagon is inserted dish is divided into a plurality of equilateral triangles, and each leg-of-mutton angle point and central point all have jack.Netted slotting dish is the square dish, and card is a gauze shape structure, and each mesh of gauze is the card jack; Its front is divided into a plurality of chequered with black and white little squares.Each inserts the back side of dish does not have figure, and jack is open-work, can two-sidedly use.Hanging wire is the fine rule or the rubber band of several different colors, on wherein a part of hanging wire length mark is arranged.
The utility model is applied widely, purposes is many, can analyze the polytype mathematical problem of answer, for example horizontal type mystery, vertical mystery, several gusts, ordered series of numbers, walk that labyrinth, number figure, graphics calculations, figure are cut apart, unicursal, permutation and combination, comprise with eliminating, tree planting recreation, reasoning problems, clock problem, application topic analyze, conventional calculating etc.
