Description
Technical field
The utility model is related to a kind of teaching aid, especially a kind of board of education for mathematics of imparting knowledge to students can pass through number
Word transformation is combined to calculate.
Background technology
It, often will be in blackboard when teacher instructs addition subtraction multiplication and division method operation when primary school or school-ager impart knowledge to students mathematics
On write full formula, so just delay very much the process of attending class, to avoid full blackboard from writing formula, it is direct that many teachers make PPT again
Displaying explanation, but such teaching method cannot increase children's study interest and improve the interest of teaching, it can not be very
Fast grasps knowledge point, and the board of education of teaching mathematics is specifically used to because the invention is a kind of and is highly desirable.
Invention content
In order to solve the problems existing in the prior art, a kind of modular number of the utility model offer puts board of education, can
Operation is done so that number to be optionally combined, is convenient for mathematical education, removes teacher from and write formula on blackboard, study can also be improved
Interest.
Technical solution is used by the utility model solves its technical problem：
For the board of education for mathematics of imparting knowledge to students, including board of education ontology, bottom plate, mathematics disk combination and the branch for supporting board of education
Frame, the several groups mathematics disk combination are placed between board of education ontology and bottom plate, and the mathematics disk combination includes mutually hanging down
The turbine and worm directly coordinated, the upper top of the worm screw are equipped with the knob for being placed in board of education body upper surface, and the worm screw passes through
Bearing is vertically fixed on board of education ontology, and the turbine is fixed on by newel on bottom plate, fixed on the top of turbine
The mathematics turntable rotated synchronously with turbine, is uniformly provided with that several bands are digital or the module of mathematic sign on the mathematics turntable,
Side on the board of education ontology in knob offers window, the size of the window can see that number in a module or
Mathematic sign.
Using the board for teaching mathematics of this design, turn knob makes worm screw drive turbine rotation, number when turbine rotation
Turntable is learned also to rotate, then the number or mathematic sign shown in module can be seen from window, the group of a continuous row
Conjunction can be combined into a formula, can individually be converted with each in this way, be combined into a formula and convert wherein one later
Number in a window just and can carry out operation, easy to operate, it is only necessary to twist knob, when the number for seeing needs or
Mathematic sign is just stopped, eliminate teacher's effort take write on blackboard, accelerate course teaching precision, also increase children
Learning interest and improve teaching interest, allow student intuitively to see, student can also be allowed to do it yourself to operate, in increase
The interactive teaching and learning of class hour, allows student to grasp knowledge faster.
It further limiting, the holder includes telescopic supporting rod and pulley, can adjust the height of board of education ontology,
To adapt to the teaching of different age group children.
It further limits, fixing axle is connected between the mathematics turntable and turbine, is equipped with vertically in the fixing axle convex
It rises, is equipped with keyway with male cooperation on the center bore inner wall of mathematics turntable, the design of keyway allows mathematics turntable and fixing axle
Between be interference fitted, prevent repeatedly rotate after matching loose and cause mathematics turntable to fall off.
Further limit, the upper surface of the board of education ontology be can writing panel, can also carry out digital mould in this way
After block algorithm, student, which also has, unapprehended hand-written can explain.
It further limits, the bottom of the supporting rod and bottom plate is rotatably connected by axis pin, can adjust teaching
Plate ontology and bottom plate towards angle, not only allow study student visual angle more preferably, also allow teaching teacher more intuitively observation and
More easily use.
Description of the drawings
Fig. 1 is the left side structural schematic diagram of the board of education for mathematics of imparting knowledge to students；
Fig. 2 is the positive structure schematic of the board of education for mathematics of imparting knowledge to students.
Specific implementation mode
In order to make those skilled in the art may be better understood, with reference to the accompanying drawings and examples to the utility model
Technical solution further illustrates.
Board of education for mathematics of imparting knowledge to students as shown in Figure 1 and Figure 2, including board of education ontology 1, bottom plate 2, mathematics turntable group
Close the holder of 3 and support board of education, the upper surface of board of education ontology 1 be can writing panel, the several groups mathematics disk combination 3
It is placed between board of education ontology 1 and bottom plate 2, the mathematics disk combination 3 includes being mutually perpendicular to 32 worm screw 31 of turbine of cooperation, institute
The upper top for stating worm screw 31 is equipped with the knob 33 for being placed in 1 upper surface of board of education ontology, and the worm screw 31 is vertically solid by bearing 34
Be scheduled on board of education ontology 1, the turbine 32 by newel 35 fix on a base plate 2, the top of turbine 32 it is fixed with
The mathematics turntable 36 that turbine 32 rotates synchronously, is uniformly provided with that several bands are digital or the mould of mathematic sign on the mathematics turntable 36
Block, the side on the board of education ontology 1 in knob 33 offer window 11, and the size of the window 11 can see that a module
Interior number or mathematic sign.
