When designing blackboard newspaper on the blackboard, teachers and students often need to draw grids (e.g. transverse lines, vertical lines), and are not easy to draw level, which is not ideal. The utility model provides a multi-purposed teaching level which consists of a level and a horizontal ruler, and is characterized in that the middle of the level is provided with a bubble mark. If the water level in the bubble in the level is balanced with the horizontal ruler, horizontal lines or vertical lines can be easily drawn. Meanwhile, the level can be also used for horizontal marking when pictures are put on.
Description
