Abstract
The teaching apparatus has screwed quadrant plate with rotating shaft inserted into the shaft hole in the support and the quadrant plate has on the surface notch mounting numeral board. It is simple in structure and flexible in use and changes arithmetic teaching into game. It can demonstrate arithmetic exercises, arithmetic game and other intelligence developing content. It is suitable for use as tool teaching children arithmetic and use as toy for adult to play intelligent game.
Description
The present invention relates to have the puzzle of displaceable element each other, particularly a kind of flexible teaching apparatus for arithmetic technique.
Mathematical education to the juvenile is to write numerical expression to educate on blackboard basically at present, the method of also useful number number in kind, they have had formative education to the juvenile, then role is not obvious but the juvenile utilized mental arithmetic and utilize mental arithmetic to carry out bonanzagram and computing, learning method is still more uninteresting, is difficult to excite juvenile's mathematical interest.Also useful brick pattern carries out arithmetical operation, but computing one problem will be put building blocks one time, also bothers.
The purpose of this invention is to provide a kind of movable calculation skill instructional device.
Task of the present invention is finished with following mode: be fitted with the rotating shaft of quadrant plate in the axis hole of pedestal, and connect with screw, quadrant plate surperficial fluted is equipped with digiboard on the groove.The quadrant plate has 2 to 9.The groove quantity on quadrant plate surface has 2-9.The pedestal shape is frame shape or plate shape or guiding principle shape frame shape.
The present invention is simple in structure, and is easy to use flexible, and the arithmetic teaching recreationization, it can show exercise question, numeral fan hides teaching and intelligence development training contents such as recreation, figure recreation.Be suitable for use as the movable teaching aid that child, juvenile is carried out arithmetic education.Also be suitable for and make adult's riddle toy.
Fig. 1 structural representation of the present invention
Fig. 2 is the A-A cut-open view of Fig. 1
Below in conjunction with accompanying drawing the present invention is described in further detail:
Present embodiment is equipped with four blocks of quadrant plates 2 on a pedestal 3, four digiboards 1 are housed on every block of quadrant plate 2.Needs for study of numbers, can increase some digiboards to be changed, for example, training in study 1-20 number, will be equipped with 20 digiboards 1, be to show a number on the every digiboard, present embodiment is equipped with 16 digiboards 1 on quadrant plate 2, then still has four digiboards 1 to change plate for standby work.
Present embodiment digiboard 1 has 20, a numeral is arranged, from 1-20 on every block of plate, totally 20 numerals, quadrant plate 2 has four, and four grooves are arranged on every block of quadrant plate, put a digiboard 1 in each groove, once can put into 16 digiboards 1 altogether, 16 numerals are promptly arranged.Pedestal 3 has one, can put four quadrant plates 2 on the pedestal 3, and connects with screw 4.
Digiboard 1 is the empty lid of square fillet, can freely put into, take out in the groove of quadrant plate 2 upper surfaces, be i.e. the groove shapes groove of fillet that is square.The following centre of quadrant plate 2 has rotation mandrel, and the mandrel centre is porose.Pedestal 3 is cubic type framework, and four jiaos is right cylinder, radially is connected with grooved, and mounting hole is arranged in the right cylinder.When the mandrel of quadrant plate 2 is plugged on 3 four jiaos of the pedestals in the cylindrical mounting hole, upwards the hole with screw 4 precession quadrant plates 2 mandrel centres pedestal 3 is connected with quadrant plate 2 from following, four quadrant plates 2 can be on pedestal 3 is that the center is freely suitable, the anticlockwise rotation with the mandrel.Digiboard 1 can also be circular empty lid, and the groove of quadrant plate 2 upper surfaces is also corresponding to be circular groove, and every digiboard 1 all can be rotated suitably for angle, to form new combination of numbers by the user in respective slot.Digiboard 1 can be to cover shape, also can be plate shaped or arc shape, takes out in all can freely pack into groove or the groove.The groove flat shape of digiboard 1 and quadrant plate 2 is square, triangle, polygon, circle, ellipse or its combination.
Show the arithmetic exercise question: by the digital equilibrium principle in the figure, the tutor can find out the adding of some roads prophet's answer, reduction algorithms exercise question in each figure, instructs and is learnt arithmetic by the trainer.
Numeral fan hides recreation: after the figure of this device digital surface is carried out balance, stay several numerals index (as staying 5 numerals), remaining is all in the past multiple, allow and determined numeral by mental arithmetic by the trainer, upset is by multiple numeral in the past again, by trainer's self check mental arithmetic result's correctness, raising is by trainer's IQ and learning initiative, the digiboard 1 that gives over to Numerical Index can be provided with arbitrarily by the tutor, and that the array of the digiboard 1 of Numerical Index commonly used is is cross, L font, T font, Z font.
Figure training: when being understood fully by the trainer in the figure after the relation between the numeral, according to the Numerical Index rule, to stay in the groove of quadrant plate 2 except that reserving the digiboard 1 of making Numerical Index in this device, remaining digiboard 1 all is not contained in the groove, allow the numeral of being found out corresponding rule by the trainer with mental arithmetic, the digiboard 1 of doing it yourself to select appropriate numeral is put in the groove that is contained in corresponding quadrant plate 2, until finishing digital balance figure.Like this, will significantly be increased, good basis has been arranged in intelligence development, help being accepted other knowledge education by the trainer by trainer's IQ.
The user can be according to own needs, after a kind of graphic operation is finished, rotate every block of quadrant plate 2, and there has been variation the mutual alignment of numeral in the then former figure, can make new digital figure again and carry out relevant computing.
