Description
Technical field
The utility model relates to a kind of teaching aid technical field, relate in particular to one for demonstrating the race between tortoise and rabbit, set up the mathematical model teaching aid of the relation between speed, time, distance.
Background technology
In primary school math teaching, need to explain the relevant application topic of common speed, time, distance, and expansion between these problems, as pursue and attack, Meeting problem etc.; There is no the aided education of teaching aid, lower student is more difficult for the understanding of this class problem.
Utility model content
In order to overcome above-mentioned technical matters, it is a kind of for demonstrating the math teaching tool for primary school of the race between tortoise and rabbit that the utility model provides, and the technical scheme of employing is as follows.
A kind of for demonstrating the math teaching tool for primary school of the race between tortoise and rabbit, it is characterized in that, comprise casing, distance scale, glass plate, show stand, rabbit mould plate, tortoise mould plate, tortoise mould plate push rod, rabbit mould plate push rod, rabbit mould plate slide block and tortoise mould plate slide block; Described casing is rectangular parallelepiped, and a vacancy is left in front side, and right side central position offers two holes; On described show stand, offer twice chute, described show stand is arranged in described casing; Described distance scale is arranged on described show stand front side; The vacancy that the front side of the casing described in described glass plate is arranged on is left; Described rabbit mould plate slide block is embedded in the chute of the described forward side of show stand, and described rabbit mould plate is installed on described rabbit mould plate slide block; Described tortoise mould plate slide block is embedded in described show stand by the chute of rear side, and described tortoise mould plate is installed on described tortoise mould plate slide block; Described rabbit mould plate push rod one end connects described rabbit mould plate slide block, the hole that one end is offered by described casing right side; Described tortoise mould plate push rod one end connects described tortoise mould plate slide block, another hole that one end is offered by described casing right side.
The beneficial effects of the utility model are: simple in structure, novel unique, and demonstration the race between tortoise and rabbit that can be vivid, thus the mathematical model between the speed of foundation, time, distance is convenient to understanding and the grasp of student to relevant knowledge greatly.
