Novel mathematics teaching-purpose protractor

Abstract

The invention discloses a novel mathematics teaching-purpose protractor. The protractor includes a protractor main body. The upper surface of the protractor main body is provided with a solar panel thereon. The protractor main body is provided with an electronic display thereon and is provided with a circuit board therein. The circuit board is provided with an integrated core processor, a storage battery, a timer, a calculator, a gravity sensor, a gyro calibration sensor, a distance sensor, and a wireless signal transmitter thereon. The protractor main body is provided with a pressure sensor thereon. The pressure sensor is in separate and electrical connection to the solar panel, the electronic display, the integrated core processor, the storage battery, the timer, the calculator, the gravity sensor, the gyro calibration sensor, the distance sensor and the wireless signal transmitter. According to the invention, the protractor has simple structure and strong practicality.

Description

technical field [0001] The invention relates to the field of teaching tools, in particular to a novel protractor for mathematics teaching. Background technique [0002] Among the teaching tools, during the use of the triangular ruler, it is often necessary to manually measure the angle and put together various shapes, which is a waste of energy and time. Due to the heavy learning pressure of students, those who are not strong in hands-on ability will inevitably feel bad. This will cause a series of emotional reactions, which will make the students have a bad mentality and affect their learning. Therefore, it is very necessary to manufacture a new type of triangle ruler for mathematics teaching. During use, it is convenient for students to operate and solve the above problems. Contents of the invention [0003] The purpose of the present invention is in order to solve the above-mentioned problem, has designed a kind of novel mathematics teaching protractor. [0004] To ach...
