Description

technical field [0001] The invention relates to the field of teaching appliances, and more specifically relates to a mobile mathematics teaching board. Background technique [0002] The teaching board is the utensil used for writing demonstrations in the education industry. Usually, the teaching board is a board placed in a classroom or a conference room, and the content is written with chalk or water-based pen to play the role of explaining and demonstrating. The predecessor of the teaching board is a blackboard. The traditional blackboard is simply to apply black paint on the surface of a hard object such as a flat wooden board or cement board, and write with chalk after the blackboard is dry. [0003] The existing mathematics teaching board is cheap and has excellent corrosion resistance. Teachers write on the blackboard is more convenient and traditional, which is easy for students to understand. It can effectively convey the knowledge points that teachers want to expres...
