Description

Mathematical-operation toy bricks

A kind of learning aid and toy of learning math basic knowledge for children.

Building blocks are the toys that liked by the various countries children, except pure recreation building blocks such as traditional building, the vehicles, have occurred various intellectual service building blocks in recent years.As Chinese character root building blocks, Music building block etc.; The mathematics game chess that occurs on the present market.Its essence also is a kind of intellectual toy bricks (composition of playing chess is few).Though existing mathematics building blocks can be used for joining together formula, all can not " automatically " provide answer.Need the player to calculate the result.Because using object is the child mostly.Often do not go out correct result, be difficult to excite the learning interest of children's game.

The purpose of this utility model is to create a kind ofly can to join formula together for children, can " automatically " provide operation result again.The mathematics building blocks that intellectual and interesting tool is strong.

The utility model is made up of main part and auxiliary.

Main part comprises 20 pieces of digital elements and two pieces of bearing-age trees.

The basic configuration of digital element is identical, just the length difference.Digital element is the stairstepping quadrangular.Have two stairstepping surfaces.6 square surface.Be equivalent to a quadrangular and cut a fritter lineal hexahedral at the ladder place.Vertical section is just in time vertically divided the surface that former quadrangular is cut equally, and the cross section then meets at right angles with vertical section, along the extended line of stepped line each stairstepping surface is divided into two rectangles.Make a distinction with different colours; These two rectangles are wide to be equated, length difference, the formula that is used for joining together the different stage respectively row operation of going forward side by side.For example special-purpose toy bricks capable of arithmetic operations, long rectangle is used for doing plus-minus, and short rectangle is used for doing multiplication and division; Because do the standard most convenient with each that long limit, rectangle outside, we can be called plus and minus calculation and multiplication and division computing limit to them respectively; On every computing limit, all put on corresponding scale and symbol respectively.The significant digit of computing and precision are by the decision of these scales and symbol (can not marking of using of child perhaps put on symbol at a small amount of quarter simply).Go in the same old way.We also are called computing face to the synthetic step surface in plus and minus calculation limit and multiplication and division computing limit.Each digital element all has two computing faces.Computing face is except being used for the addition subtraction multiplication and division computing.Also can be used for doing power, evolution, trigonometric function, plural number, vector or the like mathematical operation.Just the scale on the computing limit is different with symbol.The side that two other of digital element is bigger.One is used for the printing word, and one is used for impression and draws, and is called digital face and diagram face respectively.The literal numeral of number is corresponding with the picture of diagram face on the same digital element.What print on the numeral face is " 1 ".Then diagram face seal is a toy (or other things); What print on the numeral face is " 2 ".What then print on the diagram face is two toys (or other things); The rest may be inferred by analogy.Remaining surface can be echoed with auxiliary and be stamped various comprehensive game patterns.

Digital element has ten kinds, two pieces every kind.On digital face, be printed on " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " 10 " respectively, every kind length difference.Increase progressively regularly by certain functional relation to " 10 " by " 1 ".Their the most handy computing of length limit illustrates: the plus and minus calculation limit is unit head with the length of " 1 ", and " 2 " are two double-lengths of " 1 "." 3 " are three double-lengths of " 1 ".The rest may be inferred by analogy.Multiplication and division computing limit then is to determine that earlier a long m(of unit preferably slightly is shorter than " 1 " on plus and minus calculation limit).The length of each computing be m10gx(x=1,2 ..., 10).The computing limit of other kinds should be in addition by the functional relation value that is fit to.But needn't be placed on the outer face length limit of step surface, can be imprinted on the inside of computing face.This does not give unnecessary details one by one.

Two pieces of bearing-age trees, but two pieces can be connected and be one tree.Bearing-age tree can be done the same shape of digital element.Apparent size, length and digital element " 10 " are identical; Also can make the geometry of other interest, so that do comprehensive recreation with auxiliary.Indicate the groove and the reading of expression operation result on the bearing-age tree by corresponding functional relation.

10～15 of auxiliaries.Make various basic planes or solid geometry figure.Wherein one of right angled triangle, one in isosceles triangle, one at equilateral triangle, one of general parallelogram, one on square, one of rectangle, one of isosceles trapezoid, fan-shaped one, etc. big half garden two (can be combined into a garden), one on tetrahedrons, one in square, one of cuboid, one of Cylinder, one of spheroid (the solid geometry figure can not done).

Be printed on geometric title, the emerging pattern of entertaining and for example in kind on the surface of auxiliary.Parallelogram, rhombus, the trapezoidal angle that a pair of (or one) 60 degree are all arranged.Their bond length is consistent with the length of side of isosceles triangle.The size of all auxiliaries and auxiliary, auxiliary and main part will match simultaneously.Form various models so that cooperatively interact.

The size of digital element is unsuitable excessive.Also unsuitable too small, with children play left-hand seat.Easy to carry being as the criterion.A reference dimension is provided here: high 15mm, wide 15mm, each digital element are identical; The unit head on plus and minus calculation limit is 15mm." 2 " are 30mm." 3 " are 45mm.……。" 10 " are 150mm; The unit head of multiplication and division computing is 15mm." 2 " are 10g10 * 15 so.

Bearing-age tree is advisable with 150mm * 15mm * 15mm.

The size of auxiliary will match with main part, and a reference dimension also is provided here.The thickness of plane geometric figure is 15mm.Its surface size is respectively: the long respectively 30mm in right angled triangle three limits, 40mm, 50mm.The long 30mm of isosceles triangle waist, bottom side length 40mm.Equilateral triangle length of side 34mm.Square 30mm * 30mm.Rectangle 50mm * 30mm.General parallelogram 50mm * 34mm, rhombus 34mm * 34mm.The long 20mm of isosceles trapezoid upper base.Long 54mm, the long 34mm of hypotenuse go to the bottom.Half garden diameter is 40mm.The long 40mm of each rib of tetrahedron.Cuboid 50mm * 40mm * 30mm.Cylinder diameter 30mm, high 40mm.Sphere diameter 30mm.

The utility model has multiple use: one, young children can come digital recognition by the main part diagram.Two, join formula together with digital element.The formula of risking can be read correct result with the bearing-age tree contrast.Three, learn basic geometric figure knowledge with auxiliary.Four, main part and auxiliary combination.Can do multiple building blocks recreation such as building, instrument, implements.
