The utility model discloses a drawing board for mathematics teaching, which comprises an adjusting seat, a rotating disc is rotatably arranged at the bottom of one side of the adjusting seat, guide rods are slidably arranged at four corners of the top of the adjusting seat, a fixing plate is fixedly mounted at the tops of the guide rods, and adjusting rods are rotatably arranged on two sides of the bottom of the fixing plate. According to the clamping device, the two-way lead screw is driven to rotate by rotating the rotating disc, so that the adjusting rod at the top of the sliding block is driven to be gradually perpendicular to the sliding groove to jack up the fixing plate, the fixing plate can be driven to move downwards by controlling the two-way lead screw to rotate reversely, and the clamping plate is clamped by the clamping plate. And through mutual matching of the guide rods and the guide grooves, the fixing plate can move up and down more stably, in this way, the height of the mathematical drawing
