Abstract
A broken line graph is provided and relates to the technical field of primary school mathematics teaching aids. The broken line graph consists of a galvanized iron sheet board, a coordinate paper, a leather hose and Bucker balls, wherein the coordinate paper covers on the central portion of the galvanized iron sheet board. Preferably, Bucker balls are disposed inside the leather hose and are attracted on the galvanized iron sheet board. According to the broken line graph, a vertical coordinate and a horizontal coordinate can be set on the basis of statistics knowledge; and the leather hose with the Bucker balls inside can be adsorbed to relative positions and thus a broken line graph can be shown to students. During the whole process, no writing is needed, thereby saving teaching time, improving teaching efficiency and increasing the fascination of the students for learning. The broken line graph is characterized by simple structure and convenient operation.
Description
Technical field
The utility model relates to a kind of primary school mathematics teaching aid, particularly relates to a kind of broken line graph.
Background technology
In primary school's senior class, need study statistics rudimental knowledge, wherein broken line graph is a heavy difficult point wherein; How to let the student understand this knowledge point better; Traditional way just lets student's described point on blackboard or homework book, also has plenty of teacher and on blackboard, writes, and need take many instructional blocks of times; Reduce the efficient of teaching, do not had special teaching aid.
The utility model content
The purpose of the utility model is the deficiency to prior art, and a kind of simple in structure, easy to use, broken line graph teaching aid of saving instructional blocks of time is provided.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: a kind of broken line graph, to form by galvanized iron dermatotome, coordinate paper, leather hose and buckyballs, and said galvanized iron dermatotome is coated with coordinate paper above the middle part.
As preferably, buckyballs is equipped with in said leather hose inside, is adsorbed on the galvanized iron dermatotome.
The utility model can be provided with ordinate and horizontal ordinate according to statistical knowledge, and the leather hose that buckyballs is housed is adsorbed on corresponding position; Show broken line graph to the student; 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 utility model overall schematic,
Fig. 2 is that the utility model uses synoptic diagram.
Among the figure: 1. galvanized iron dermatotome, 2. coordinate paper, 3. leather hose, 4. buckyballs.
Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model.
As shown in the figure, the broken line graph in the utility model is mainly used in Primary-School Pupils in Learning broken line statistical knowledge, utilizes the attraction principle between buckyballs 4 and the galvanized iron dermatotome 1 to make.Ordinate and horizontal ordinate are set according to actual needs, the leather hose that buckyballs 4 is housed 3 is adsorbed on corresponding position, show broken line graph to the student.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 broken line graph.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.
