Description
Technical field:
The utility model relates to the realia technical field, is specifically related to a kind of novel teaching aid.
Background technology:
At present, school teacher is in the process of giving lessons, the courses such as special picture mathematics, physics, often need to draw, measurement etc., sometimes a width of cloth figure needs multiple educational aid to be used in conjunction with, so not only bother, but also wasted a large amount of time, bring very large trouble to instructors, and in teaching process, the content as trigonometric function, teacher's demonstration that also often uses a model is helped students and is remembered, understand, also do not occur on the market a kind of teaching aid that both can demonstrate trigonometric function simultaneously also can aided drawing now.
The utility model content:
The purpose of this utility model provides a kind of new teaching apparatus, it is simple in structure, novel in design ingenious, easy to operate, bring great convenience for the education and instruction of instructors, have simultaneously the trigonometric function apparatus for demonstrating, can help the student better to understand trigonometric function, help the student better to remember, reached good results of learning.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises measures ruler 1, square demonstration board 2, protractor 3, pointer 4, carriage 5 and pin 6, an end of measuring ruler 1 is connected with the centre position that square demonstration board 2 is connected with protractor by pin 6, the top of protractor 3 is provided with pointer 4, measures on the ruler 1 and slidely connects carriage 5.
The top of described carriage 5 is provided with several chalk putting holes 5-1, and the diameter of chalk putting hole 5-1 is placed chalk less times greater than the diameter of chalk in the chalk putting hole 5-1.
Be provided with coordinate scale line 2-1 around the described square demonstration board 2.
