Abstract
The utility model provides an arithmetic teaching demonstration device, which belongs to the technical field of teaching devices and structurally comprises a base and numeral turnover board stands. The bottoms of the numeral turnover board stands are connected with the base in an inserted manner through inserting slots, the top end of each numeral turnover board stand is provided with a turnover shaft, a numeral board is connected onto each turnover shaft in a penetrating manner, a calculation runner frame is arranged on the base, a calculation runner is arranged at the top of the calculation runner frame, and operator boards are arranged at the edges of the calculation runner respectively. An equal sign board stand is further connected to the base in an inserted manner through an inserting slot. By means of the inserting connection mode, the numeral turnover board stands and the calculation runner are combined to form a calculation formula, a plurality of calculation formulas can be combined once for students to learn calculation, calculation ability of the students can be effectively improved, quick oral arithmetic and metal arithmetic abilities can be practiced, teaching is facilitated, and teaching quality level can be improved.
Description
Technical field
The utility model relates to the teaching equipment technical field, specifically a kind of algorithm calculations teaching demonstration device.
Background technology
General, in the arithmetic teaching process of mathematics, a lot of arithmetic formulas of teachers association's writing on the blackboard on blackboard; Come to student's calculating impart knowledge to students and strengthen the training, various calculating formula will be write for a long time on blackboard, and takies time in classroom; Take turns the writing that calculating also will be wiped blackboard later again when this, write new calculating formula then again, its process is loaded down with trivial details; Expend time in, make classroom instruction uninteresting, influence instructional blocks of time and quality of instruction.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of algorithm calculations teaching demonstration device is provided.
The technical scheme of the utility model realizes by following mode, this algorithm calculations teaching demonstration device, and its structure comprises base and digital board turning frame; Peg graft through slot and base in numeral board turning frame bottom; Numeral board turning frame top is provided with trip shaft, and cross-under has digital signage on the trip shaft, and base is provided with the computing wheel carrier; Computing wheel top of the trellis is provided with the computing runner, and the computing runner is respectively arranged with the operational symbol label on the edge.
The number plate frame such as also be plugged with on the base, wait the number plate frame through slot and base grafting.
The beneficial effect that the utility model is compared with prior art produced is:
This algorithm calculations teaching demonstration device adopts the mode of pegging graft; Utilize digital board turning frame and computing runner to be combined into calculating formula; Can once make up a plurality of calculating formulas and supply the student to calculate study, effectively improve student's computing power, temper the ability of mental arithmetic fast and mental arithmetic; Help teaching, the level of improving the quality of teaching.
This algorithm calculations teaching demonstration device is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
