## Abstract

The utility model relates to a Montessori mathematical rotary calculation teaching aid, which comprises a base, supports, a rotary shaft and five hexagonal bodies, wherein the supports are connected with both ends of the base to form a U shape, and the rotary shaft is fixedly connected with the tops of the supports through fixed rings. Preferably, the five hexagonal bodies are sequentially mounted on the rotary shaft, and are partitioned from one another by clips capable of being moved on the shaft. According to the learning progress of pupils, numbers for operation to be explained are written on the corresponding hexagonal bodies and the hexagonal bodies are mounted on the rotary shaft, so that related calculation can be demonstrated and explained; in the whole process, writing is not needed, consequently, teaching time is saved, the teaching efficiency is increased, and the interestingness of learning is increased; and the Montessori mathematical rotary calculation teaching aid has a simple structure, and is convenient to operate.

## Description

Teaching aid is calculated in the upset of Meng Tesuoli mathematics
Technical field
The utility model relates to a kind of primary school mathematics teaching aid, particularly relates to a kind of Meng Tesuoli mathematics upset and calculates teaching aid.
Background technology
The educational thought that the educationist Meng Tesuoli that twentieth century is world known foundes just meeting current quality-oriented education, and its corresponding teaching aid costs an arm and a leg, and is not suitable for popularizing.And in the conventional teaching, teacher need write on the blackboard of being everlasting, and need take many instructional blocks of times, has reduced the efficient of teaching.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides a kind of Meng Tesuoli mathematics upset simple in structure, easy to use, that save instructional blocks of time to calculate teaching aid.
For solving the problems of the technologies described above; The utility model is taked following technical scheme: teaching aid is calculated in a kind of Meng Tesuoli mathematics upset; Be made up of base, support, turning axle and hexahedron, said base both sides are connecting to prop up puts up the U type, is being fixedly connected turning axle through set collar above the support.
As preferably, be inserted with five hexahedrons above the said turning axle in order, go up removable folder with axle between each hexahedron and separate.
The utility model can be in the progress according to Primary-School Pupils in Learning, with the computing of needs explanation, on the hexahedron of correspondence, fills in numeral and is plugged on the turning axle; Thereby demonstrate and explained correlation computations; In whole process, need not write, thereby save instructional blocks of time, improved efficiency of teaching; It is interesting to have increased study, has simple in structure, convenience operation.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Among the figure: 1. base, 2. support, 3. set collar, 4. turning axle 5. spool is gone up removable folder, 6. hexahedron and axle connecting hole, 7. a hexahedron.
Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model.
As shown in Figure 1, the Meng Tesuoli mathematics upset in the utility model is calculated teaching aid and is mainly used in the computing of Primary-School Pupils in Learning addition subtraction multiplication and division method, and the numeral on each hexahedron can expand and change according to actual needs; According to demand, arrangement is plugged on the turning axle 4 in order then, goes up removable folder 5 with axle between each hexahedron and separates; During use; As required, first hexahedron 7 or second hexahedron 7 of only needing to rotate turning axle 4 can be accomplished one group of computing, rotate the hexahedron 7 that has sign of operation; Can change arithmetic, and then the hexahedron that lets the student rotate the back is found out answer or directly answer.Can levy explanation, class exercise down.Excited students'interest in learning and manipulative ability, residence is taught in object for appreciation, thereby has saved instructional blocks of time, improved efficiency of teaching, has simple in structure, convenience operation.
In a word, the utility model provides the upset of Meng Tesuoli mathematics to calculate teaching aid.The above; Be merely a part of embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
