Abstract
The utility model belongs to the technical field of teaching aids for teaching math and relates to a novel teaching chalkboard with a mathematical formula prompt board. The novel teaching chalkboard comprises a chalkboard body, a holding groove, sliders, the prompt board, a prompt board frame, a handle, a plurality of prompt board slides, and sliding posts. The novel teaching chalkboard is characterized in that the holding groove is arranged in the left surface of the chalkboard body, the prompt board frame is inserted into the holding groove, the sliders are fixedly connected to the middles of the upper and lower end surfaces of the prompt board frame, the handle is fixedly connected to the middle of the left surface of the prompt board frame, the prompt board slides are arranged in the inner upper and lower surfaces of the prompt board frame in the transverse direction, each sliding post is inserted into one of the upper and lower prompt board slides, the prompt board is fixed between the sliding posts, the sliding posts are fixedly connected to the left and right edges of the top surface of the prompt board and left and right edges of the bottom end of the prompt board respectively. By the use of the novel teaching chalkboard, the problem that students are unable to remember formulas and to keep up with teaching ideas of teachers when the teachers give a lesson is solved, the teaching ideas of the teachers can be clear, and the students can keep up with the ideas of the teachers.
Description
Technical field
The utility model belongs to teaching technique with the apparatus field, is specifically related to a kind of new teaching band mathematical formulae notice board blackboard.
Background technology
In long-term mathematical education practice; teacher often can use multiple mathematical formulaes in teaching process; in the time giving lessons, student often cannot remember the formula that teacher is used the very first time, student often departed from teachers' instruction thinking make student's thinking and teacher's thinking inconsistent.
Summary of the invention
The purpose of this utility model is: in order to solve teacher in teaching process, what can use at any time shows mathematical formulae student's reference, prevent that teacher student in the time giving lessons from cannot remember formula and not catch up with teachers' instruction thinking, can make teachers' instruction clear thinking and student can catch up with teacher's thinking, its technical scheme is as follows:
Band mathematical formulae notice board blackboard for a kind of new teaching, it comprises blackboard 1, standing groove 2, slide block 3, notice board 4, notice board frame 5, attacker 6, notice board chute 7, traveller 8, it is characterized in that: described blackboard 1 left-hand face is provided with standing groove 2, described standing groove 2 inside are fitted with notice board frame 5, described notice board frame is fixedly connected with slide block 3 in top end surface middle Shang Xia 5, described notice board frame 5 left-hand face middles are fixedly connected with attacker 6, the inner upper and lower surface of described notice board frame 5 is laterally provided with several notice board chutes 7, upper and lower each described notice board chute 7 inside are fitted with traveller 8, between described traveller 8, be fixedly connected with notice board 4, on described notice board 4, top end surface left and right edges place and left and right edges place, lower top are respectively fixedly connected with described traveller 8, the inner upper and lower surface of described standing groove 2 is respectively provided with convex chute, described convex chute and described slide block 3 cooperatively interact, and the described placement 2 interior groove degree of depth are consistent with described notice board frame 5 length, the length of described notice board 4 is 1/3rd length of described notice board frame 5 inner widths, described traveller 8 is inserted in described notice board 4 upper and lower surfaces, and be fixedly connected with by spring.
The beneficial effects of the utility model are: in order to solve teacher in teaching process, what can use at any time shows mathematical formulae student's reference, prevent that teacher student in the time giving lessons from cannot remember formula and not catch up with teachers' instruction thinking, can make teachers' instruction clear thinking and student can catch up with teacher's thinking.
brief description of the drawings:
Fig. 1 is overall structure schematic diagram of the present utility model.
detailed description of the invention:
With reference to band mathematical formulae notice board blackboard for a kind of new teaching described in Fig. 1, it comprises blackboard 1, standing groove 2, slide block 3, notice board 4, notice board frame 5, attacker 6, notice board chute 7, traveller 8, it is characterized in that: described blackboard 1 left-hand face is provided with standing groove 2, described standing groove 2 inside are fitted with notice board frame 5, described notice board frame is fixedly connected with slide block 3 in top end surface middle Shang Xia 5, described notice board frame 5 left-hand face middles are fixedly connected with attacker 6, the inner upper and lower surface of described notice board frame 5 is laterally provided with several notice board chutes 7, upper and lower each described notice board chute 7 inside are fitted with traveller 8, between described traveller 8, be fixedly connected with notice board 4, on described notice board 4, top end surface left and right edges place and left and right edges place, lower top are respectively fixedly connected with described traveller 8, the inner upper and lower surface of described standing groove 2 is respectively provided with convex chute, described convex chute and described slide block 3 cooperatively interact, and described standing groove 2 internal depth are consistent with described notice board frame 5 length, the length of described notice board 4 is 1/3rd length of described notice board frame 5 inner widths, described traveller 8 is inserted in described notice board 4 upper and lower surfaces, and be fixedly connected with by spring.
When use, first fasten attacker 6 by notice board frame 5 from the interior pull-out of standing groove 2, then by the notice board 4 that pushes away oily mathematical formulae in the interior slip of the inner chute 7 of notice board frame 5, impassioned notice board 4 pulls out in standing groove 2 simultaneously, sometimes in the time solving a problem, easily use multiple formula and formula not on a notice board 4 time, can be by placed side by side two notice boards 4 and two notice boards 4 can be showed to student simultaneously.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
